Answer:

3600J

Explanation:

The amount of energy transferred in two minutes by the given heater is 3600J of energy.

This energy causes a transfer of kinetic energy to the copper. To solve this problem;

             60 seconds  =  1 minutes

            In two minutes, the number of seconds = 2 x 60  = 120seconds

So, on the table, at 120 seconds, 3600J of energy would have been transferred.

Which characteristic does inertia describe

Answers

Answer:

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object's speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.

Answers

Answer:

work = power × time

time = work ÷ power

Explanation:

Power is defined as the rate at which work is done.

 It is mathematically expressed as;

     Power  = [tex]\frac{work}{time}[/tex]  

 From this expression, if we cross multiply, we get;

        work  = power x time

Also,   if we divide both sides by power, we get;

      time  = work ÷ power

A closely wound search coil has an area of 3.13 cm2, 135 turns, and a resistance of 61.1 Ω. It is connected to a charge-measuring instrument whose resistance is 44.4 Ω. When the coil is rotated quickly from a position parallel to a uniform magnetic field to one perpendicular to the field, the instrument indicates a charge of 3.44×10−5 C . What is the magnitude of the magnetic field?

Answers

Answer:

Explanation:

Let the magnitude of magnetic field be B .

flux passing through the coil's  = area of coil x field x no of turns

Φ = 3.13 x 10⁻⁴ x B x 135 = 422.55 x 10⁻⁴ B .

emf induced = dΦ / dt , Φ is magnetic flux.

current i = dΦ /dt x 1/R

charge through the coil = ∫ i dt

= ∫   dΦ /dt x 1/R dt

= 1 / R ∫ dΦ

= Φ / R

Total resistance R = 61.1 + 44.4 = 105.5 ohm .

3.44 x 10⁻⁵ = 422.55 x 10⁻⁴ B / 105.5

B = 3.44 x 10⁻⁵ x 105.5  / 422.55 x 10⁻⁴

= .86 x 10⁻¹

= .086 T .

A student spots an unknown sample on a TLC plate. After developing in hexanes/ethyl acetate 50:50, he/she saw a single spot with an Rf of 0.55. Does this indicate that the unknown material is a pure compound? What can be done to verify the purity of the sample?

Answers

Answer:

See explanation

Explanation:

A pure sample is known to give one spot on a chromatogram. This is the first indication that the substance is a pure substance. Since the student saw a single spot, the unknown substance is pure.

Subsequently, the substance can be boiled since it is a liquid. Impure substances boil over a range of temperatures. If the substance is pure, it will have a sharp boiling point which can be compared with boiling points of known substances recorded in literature hence the substance can be correctly identified.

The given unknown material or compound is a pure compound - yes, it has only one spot.

In the given TLC plate there is only one single spot found thus we can say it is the pure compound as If an impurity is present along with the major compound then there we could observe more spots other than the major compound.

The verification of the purity of the sample can be tested by a general procedure

conduct the TLC of the given compound and a separate TLC consisting of the pure compoundcompare the Rf values of both platesif it matches with the Rf value of the pure compound then the given compound is confirmed. the TLC plate has no spots other than the main compound therefore, it is a pure one.

Thus, The given unknown material or compound is a pure compound - yes, it has only one spot.

Joseph remembers reading that for a particular pressure, P1, there is a maximum height to which a fluid can rise. He reasons that in this case the pressure (P2) must drop to zero so that the water can no longer flow to increased heights. He decides to check if the simulation can be made to demonstrate such conditions. He decides to make A2 as small as possible in the simulation (2.2 cm2) so that he increases the speed of the fluid in tube 2 as high as is possible (he decides to do this after examining the continuity equation). He then calculates the height of the fluid under these conditions where the pressure would fall to zero so that the fluid could no longer be made to flow under the conditions set up in the simulation. He then runs the simulation under the largest Δy allowed to check his calculation. What does Joseph calculate for the maximum height?

Answers

Answer:

h = P₁ / 9800

Explanation:

This is a fluid mechanics problem, let's write the Bernoulli equation at two points, the subscript 1 for the lowest point and the subscript of 2 for the point with the highest height.

           P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ ρ v₂² + ρ g y₂

           

at the highest point P₂ = 0 and v₂ = 0,

          P1 + ½ ρ v12 = ρ g (y₂ -y₁)

we use the continuity equation for the velocity at the lowest point

          A₁ v₁ = A₂ v₂

Since the velocity at the highest point is zero, this implies from the equation that the velocity at the lowest point is also zero. In the no-flow condition

             P₁ = ρ g (y₂ -y₁)

             h = y₂-y₁

             h = P₁ /ρ g

the density of water is ρ = 1000 kg / m³ and g = 9.8 m/s², we substitute

              h = P₁ / 9800

Let's do a calculation, suppose that P₁ = 1 10⁵ Pa

             h = 1 10⁵ / 9800

             h = 10.2 m

A student drops a 0.4kg ball from a height a of 49m above the ground. Neglect drag. Answer each of the following questions about the ball during the flight.

What is the magnitude of the net force on the ball?
What is the magnitude of the ball's acceleration?
How long does the ball take to hit the ground?
What is the ball's speed just before striking the ground?

Answers

• The only force acting on the ball, and thus the net force, is due to its own weight, with magnitude

w = m g = (0.4 kg) (9.8 m/s²) ≈ 3.9 N

pointing downward.

• The ball is in free fall, so its acceleration is g = 9.8 m/s² (also pointing downward).

• The ball is dropped from a height of 49 m, so its height y at time t is

y = 49 m - 1/2 g t ²

Set y = 0 and solve for t :

0 = 49 m - 1/2 g t ²

t ² = (98 m) / g

t = √((98 m) / g) = √(10) s ≈ 3.2 s

• The ball's velocity v at time t is

v = - g t

so that at the time found previously, the ball will have attained a velocity of

v = - g (3.2 s) ≈ -31 m/s

and thus a speed of about 31 m/s.

A top sprinter reached his maximum instantaneous velocity of 12.28 meters per second 7.17 seconds after leaving the blocks. Calculate his acceleration. All key steps must be shown.
I am very confused will you please help me!!

Answers

Answer:

Here we will assume two things.

His acceleration is constant until he reaches his maximum velocity and then he stops accelerating.

When he leaves the blocks, his velocity is "zero", meaning that the initial velocity is zero.

Then:

For the acceleration of the sprinter we will have a constant, A:

a(t) = A.

for the velocity we need to integrate over time, we will get

v(t) = A*t + v0

Where v0 is a constant of integration, and this is the initial velocity, as we already said, this will be zero, so the velocity equation is:

v(t) = A*t

We know that at t = 7.17 seconds, his velocity is 12.28m/s

then:

v(7.17s) = 12.28m/s = A*7.17s

               12.28m/s/7.17s = 1.71 m/s^2 = A.

The acceleration is: 1.71 m/s^2  for 0 < t < 7.17s

                                  0 m/s^2  for  7.17s < t.

This is because that was his maximum velocity, then after that time he can not accelerate more.

the sputnik 1 satellite orbited earth (mass=5.98 x 10^24 kg) in a circle of radius 6.96 x 10^6 m. what was its orbital velocity?

Answers

Answer:

v = 4.79 10³ m / s

Explanation:

For this exercise we will use the universal law of gravitation and Newton's second law

          F = G M m / r²

where G is the gravitational constant, m the mass of the satellite, M the mass of the Earth, r the distance from the center of the planet to the satellite

           F = m a

since the satellite has a circular path, the acceleration is centripetal

          a = v² / r

we substitute

          G M m / r² = m v² / r

           G M / r = v²

   

We calculate

          v² = 6.67 10⁻¹¹ 5.98 10²⁴ / 6.96 10⁶

          v = √ (22.94 10⁶)

Explanation:

The property of matter that will keep the body in motion when the car comes to a halt is the inertia force.

Inertia is the ability of a body to remain in static position. It is the tendency to remain in a stable condition where there is no motion.

Newton's first law is the law of inertia and it states that a body remain in a state of rest or of uniform motion unless acted upon by an external force. The ability to remain in state of rest by a body is predicated on the force of inertia.
