A block of wood weighs 160 N and has a specific gravity of 0.60. To sink it in fresh water requires an additional downward force of:_______A. 54N B. 64N C. 96N D. 110N E. 240N
Answer:
Your answer is: D) 110N
Hope this helped : )
Explanation:
In order for the wood to sink, it's specific gravity must equal 1 (or greater).
Specific gravity = .6 kg/m^3= Mass/volume
F (Newtons or kg x m/s^2) = Mass*9.8m/s^2.
Therefore, Mass = 160 N / 9.8 m/s^2= 16.32 kg
Volume = Mass/Specific Gravity = 16.32kg/.6 kg/m^3 = 27.2 m^3
Desired Specific gravity = 1 = (Mass + additional force/9.8m/s^2)/Volume = (16.32 kg +X / 9.8m/s^2)/27.2m^3
Solving for the additional force: X = 106.66...N
The answer is D, 110 N will be required to sink the block of wood.

A satellite is a large distance from a planet, and the gravitational force from the planet is the only significant force exerted on the
satellite. The satellite begins falling toward the planet, eventually colliding with the surface of the planet. As the satellite falls,
which of the following claims is correct about how the force that the planet exerts on the satellite Fps changes and how the force
that the satellite exerts on the planet Fsp changes, if at all? What reasoning supports this claim?
A
Fps and Fs both increase. The gravitational forces that two objects exert on one another decrease as the
separation between the objects increases, and these forces are always equal in magnitude.
B
Fps increases while Fsp remains constant. The gravitational force exerted by a planet on a satellite decreases
as the separation between the two objects increases, and the force exerted by the satellite on the planet remains
negligibly small.
с
Fps remains constant while Fgp increases. The gravitational force exerted by a planet on a satellite is a constant
equal to the weight of the satellite, and the gravitational force exerted by the satellite on the planet decreases as
the separation between the two objects increases.
D
Fps and Fs both remain constant
. The gravitational forces that a planet and a satellite exert on one another is a
constant equal to the weight of the satellite.
Answer:
None of the provided reasoning correct.
Explanation:
Let d be the distance between the center of the planet having mass M and the satellite having mass m.
The gravitational force acting between the planet and the satellite is
[tex]F= \frac {GMm}{d^2}\cdots(i)[/tex]
where G is the universal gravitational constant, d is the distance between the center of two bodies having masses M and m.
This gravitational force, F, is the mutual force between both the objects, so
[tex]F=F_{ps}=F_{sp}[/tex]
Where [tex]F_{ps}[/tex]: the force that the planet exerts on the satellite and
[tex]F_{sp}[/tex] the force that the satellite exerts on the planet.
So, from equation (i),
[tex]F_{ps}=F_{sp}=\frac {GMm}{d^2}\cdots(ii)[/tex]
As the satellite is falling towards the planet, to the distance, d, between the center of the planet and satellite is decreasing.
Now, from equation (ii), as [tex]F_{ps}[/tex] and [tex]F_{sp}[/tex]are inversely proportional to [tex]d^2[/tex]. So, both [tex]F_{ps}[/tex] and [tex]F_{sp}[/tex] increase on decreasing d.
Hence, both [tex]F_{ps}[/tex] and [tex]F_{sp}[/tex] increase as the gravitational forces that two objects exert on one another increases as the separation between the objects decreases, and these forces are always equal in magnitude.
None of the provided reasoning correct.

If a 6 volt battery is connected in series to resistances of 2 ohms, 8 ohms, and 14 ohms, what is the amount of the current that is flowing?
Answer:
I = 0.25 [amp]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance.
V = I*R
where:
V = voltage [Volt]
I = amperage or current [amp]
R = resistance [ohm]
Since all resistors are connected in series, the total resistance will be equal to the arithmetic sum of all resistors.
Rt = 2 + 8 + 14
Rt = 24 [ohm]
Now clearing I for amperage
I = V/Rt
I = 6/24
I = 0.25 [amp].

If a leaf falls from a tree, has work been done on the leaf? Explain.
Answer:
Hope this helps!
If a leaf falls from a tree, has work been done on the leaf, yes gravity do positive work and restive force do negative work.
What is work?
Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement. In its simplest form, it equals the product of the force's magnitude and the distance travelled for a constant force directed in the direction of motion.
When the force has a component that is parallel to the displacement, positive work results. A system gains energy via constructive effort. When the force contains a component that is opposed to or against the displacement, negative work results. Energy is removed from the system or lost through negative labor.
If a leaf falls from a tree, has work been done on the leaf, yes gravity do positive work and restive force do negative work.

A 120-kg roller coaster cart is being tested on a new track, and a crash-test dummy is loaded into it. The roller coaster starts from rest at point A which is 35 m above the ground. The cart is observed to roll down the track to point B, which is 10 m above the ground. In your own words, what physics ideas would you be able to use to predict how fast the cart is moving at point B? What calculations would you use, what things would you be measuring, and what physics principles or laws would you use to make this calculation?
Answer:
v₂ = 22.13 m/s
We need to measure heights of both points and the law of conservation of energy is applied to measure this speed.
Explanation:
In order to find the speed at the point B, we will use the Law of conservation of energy between points A and B to get the required results, as follows:
Total Energy of Cart at Point A = Total Energy of Cart Point B
K.E at A + P.E at A = K.E at B + P.E at B
(1/2)mv₁² + mgh₁ = (1/2)mv₂² + mgh²
(1/2)m(v₁² - v₂²) = mg(h₂ - h₁)
(1/2)(v₁² - v₂²) = g(h₂ - h₁)
where,
v₁ = velocity of cart at Point A = 0 m/s
v₂ = Velocity of Cart at Point B = ?
h₁ = height of point A relative to the ground = 35 m
h₂ = height of point B relative to the ground = 10 m
g = 9.8 m/s²
Therefore,
(1/2)[(0 m/s)² - v₂²] = (9.8 m/s²)(10 m - 35m)
- v₂² = - (2)(245 m²/s²)
v₂ = √(490 m²/s²)
v₂ = 22.13 m/s
We need to measure heights of both points and the law of conservation of energy is applied to measure this speed.

When a 5.0 kg box is hung from a spring, the spring stretches to 50 mm beyond its relaxed length. (a) In an elevator accelerating upward at 2.0 m/s2 , how far does the spring stretch with the same box attached? (b) How fast and in which direction should the elevator accelerate for the spring stretch to be zero (that is, the spring returns to its relaxed length)?
Answer:
a) the spring will stretch 60.19 mm with the same box attached as it accelerates upwards
b) spring will be relaxed when the elevator accelerates downwards at 9.81 m/s²
Explanation:
Given that;
Gravitational acceleration g = 9.81 m/s²
Mass m = 5 kg
Extension of the spring X = 50 mm = 0.05 m
Spring constant k = ?
we know that;
mg = kX
5 × 9.81 = k(0.05)
k = 981 N/m
a)
Given that; Acceleration of the elevator a = 2 m/s² upwards
Extension of the spring in this situation = X1
Force exerted by the spring = F
we know that;
ma = F - mg
ma = kX1 - mg
we substitute
5 × 2 = 981 × X1 - (5 ×9.81 )
X1 = 0.06019 m
X1 = 60.19 mm
Therefore the spring will stretch 60.19 mm with the same box attached as it accelerates upwards
B)
Acceleration of the elevator = a
The spring is relaxed i.e, it is not exerting any force on the box.
Only the weight force of the box is exerted on the box.
ma = mg
a = g
a = 9.81 m/s² downwards.
Therefore spring will be relaxed when the elevator accelerates downwards at 9.81 m/s²
The extension of the spring in the elevator is 60 mm.
For the extension of the spring to be zero, the elevator must be moving downwards under free fall.
The given parameters;
mass of the box, m = 5 kgextension of the spring, x = 50 mm = 0.05 mThe spring constant is calculated as follows;
F = kx
mg = kx
[tex]k = \frac{mg}{x} \\\\k = \frac{5 \times 9.8}{0.05} \\\\k = 980 \ N/m[/tex]
The tension on the spring in an elevator accelerating upwards is calculated as follows;
T = mg + ma
T = m(g + a)
T = 5(9.8 + 2)
T = 59 N
The extension of the spring is calculated as follows;
[tex]T = kx\\\\x = \frac{T}{k} \\\\x = \frac{59}{980} \\\\x = 0.06 \ m\\\\x = 60 \ mm[/tex]
For the extension of the spring to be zero, the elevator must be under free fall, such that the tension on the spring is zero.
For free fall, a = g
T = m(g - a) = 0

state newton's three laws of motion
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Ex: You roll a ball. It slows down by friction.
II. Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
Ex: You cannot kick a brick wall down, but you can kick a soccer ball because the brick wall is more massive.
III. For every action there is an equal and opposite re-action.
Ex:when a rocket lifts off, the rocket's action is to push down on the ground with the force of its engines, and the reaction is that the ground pushes the rocket upwards with an equal force.

A 40g bullet traveling at 450 m/s passed through a board and comes out traveling 300m/s. The board is 7.6cm thick. What is the force of friction applied by the wood to the bullet?
Answer:
f = 29605.2 [N]
Explanation:
To solve this problem we must use the following equation of kinematics, then use Newton's second law.
[tex]v_{f}^{2} =v_{o}^{2} -2*a*x[/tex]
where:
Vf = final velocity = 300 [m/s]
Vo = initial velocity = 450 [m/s]
a = acceleration [m/s²]
x = distance = 7.6 [cm] = 0.076 [m]
Now replacing and clearing a
2*a*0.076 = (450² - 300²)
a = 740131.57 [m/s²]
Now using Newton's second law which tells us that the force on a body is equal to the product of mass by acceleration.
f = m*a
where:
f = friction force [N]
m = mass = 40 [g] = 0.04 [kg]
f = 0.04*740131.57
f = 29605.2 [N]
You are building a house of cards. Explain how you know if the forces
acting on the cards are not balanced
Answer:
Equilibrium
Explanation:
For something to be balanced like a house of cards all forces acting on it have to be in equilibrium.
All the cards will fall down if they the forces acting on them aren't balances. That's how, it can be known that the forces acting on the cards are not balanced.
What are balanced force and unbalanced force?The forces acting on a body are said to be balanced if the total force of all the forces acting on it equals zero. Let's examine a few instances of balanced forces to better comprehend how the motion of the body is unaffected.
Unbalanced forces are those acting on a body when the net force acting on the body is greater than zero. The body alters its state of motion when unbalanced forces act on it.
If the forces acting on the cards are not balanced, every card will fall. It is possible to determine that the forces affecting the cards are not balanced in this way.
