Heat transfer by movement of heated materials is called convection. Heat that radiates from the ground initiates convection cells in the atmosphere.
Dump Tower is 96 stories tall. A small, 0.6-kg object is dropped over the side of the roof of the tower and accelerates toward the ground. Track the object for its entire fall. Each story of this tower is 3.01 meters tall.
What is the accelertion due to gravity of the planet and what is the impact speed of the object you dropped? Note: Time of fall is 12.60s
Answer:
Explanation:
height of one floor = 3.01 m
height of 96 floor h = 96 x 3.01 = 288.96 m
time of fall t = 12.6 s
h = 1/2 g x t²
288.96 = 1/2 x g x 12.6²
g = 3.64 m /s²
v = u + gt
v = 0 + 3.64 x 12 .6
= 45.86 m /s
velocity of impact = 45.86 m /s .

430 N is applied to a 250 kg object. What is the acceleration?
Answer:
a= 1.72 m/sec/sec
Explanation:
F=ma , here force is given as 430N and mass as 250 kg so using the formula acceleration can be calculated as follows
∴F=ma
1 N= 1 kg m[tex]s^{-2}[/tex]
[tex]a=\frac{F}{m}[/tex]
[tex]a=\frac{430 kg m/sec/sec}{250 kg}[/tex]
a= 1.72 [tex]ms^{-2}[/tex]
The amount of oxygen in the reactants in 4 atoms. In the products, the oxygen is distributed to water and gas. Which coefficient would be placed in front of water and oxygen
Answer:
2 for water(H2O)
1 for oxygen (O2)
Explanation:
This question is describing the decomposition of hydrogen peroxide (H2O2). Hydrogen peroxide (H2O2), which is the reactant gets broken down into water (H2O) and oxygen gas (O2). The chemical equation is as follows:
2H2O2 ---> 2H2O + O2
As described in the question, the amount of oxygen in the reactants (H2O2) is 4 atoms. The products are water and oxygen gas. To ensure that the equation is balanced, we have to use coefficients.
- Coefficient 2 has been placed in front of the water molecule to balance the number of hydrogen atoms (4) and oxygen atoms (4).
- The coefficient in front of the Oxygen gas remains 1.

17. At what speed must an object be launched vertically upward for the
object to reach a maximum height of 16 meters above its starting position.
(Do not include units, do not include a sign, use 3 sig figs) *
===============================================
Explanation:
When starting at a height of 0, and initial velocity v, the equation of projectile motion is
y = -4.9x^2 + v*x
Where x is the time in seconds and y is the height at time x.
The vertex (h,k) of this parabola is the highest point. In general the vertex has its x coordinate at h = -b/(2a), so,
h = -b/(2a)
h = -v/(2*(-4.9))
h = v/(9.8)
Plug this into the first equation shown above. Also, plug in y = 16. Solve for v.
So we get the following.
y = -4.9x^2 + v*x
16 = -4.9(v/9.8)^2 + v*(v/9.8)
16 = (-5/98)v^2 + (5/49)v^2
16 = (-5/98)v^2 + (10/98)v^2
16 = (-5/98+10/98)v^2
16 = (5/98)v^2
(5/98)v^2 = 16
v^2 = 16*(98/5)
v^2 = 313.6
v = sqrt(313.6)
v = 17.708754896943
v = 17.7
The starting velocity must be roughly 17.7 meters per second.

Answer:
A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.
Explanation:
You know that:
3.25 cm length of rope weighs 61.40 grams .There are 28.3495 grams in an ounce .There are 2.54 centimeters in an inch.The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), knowing the values a, b and c and x being the unknown, we must apply the direct rule of three as follows:
a ⇒ b
c ⇒ x
So [tex]x=\frac{c*b}{a}[/tex]
To find the number of ounces a 19.45-inch length of the same string would weigh, you apply the following rules of three:
If there are 2.54 centimeters in 1 inch, how many centimeters are there in 19.45 inch?[tex]centimeters=\frac{19.45 inch*2.54 centimeters}{1 inch}[/tex]
centimeters=49.403
Now, if 3.25 centimeters long it weighs 61.40 grams, then 49.403 centimeters long, how many grams does it weigh?[tex]grams=\frac{49.403 centimeters*61.40 grams}{3.25 centimeters}[/tex]
grams= 933.34
Finally, if there are 28.3495 grams in 1 ounce, in 933.34 grams how many ounces are there?[tex]ounces=\frac{933.34 grams*1ounce}{28.3495 grams}[/tex]
ounces= 32.92
A 19.45-inch-long segment of the same rope would weigh 32.92 ounces.

a sample o aluminum is put in 10.5 mL of water. if the water rises to 13.5 mL when the aluminum is added, what is the density of the aluminum if it has a mass of 8.1 g
Answer:
The answer is 2.7 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
volume = final volume of water - initial volume of water
volume = 13.5 - 10.5 = 3 mL
From the question we have
[tex]density = \frac{8.1}{3} \\ [/tex]
We have the final answer as
2.7 g/mLHope this helps you

is heat the same as thermal energy?
Answer:
To be 100% honest im nkt sure but I'm gonna take a gander. yes i think it is the same
Answer:
Yes heat is the same as thermal energy
Explanation:
Heat is the same thing as thermal because Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ law of thermodynamics).

- A 300 kg box of supplies is dropped from a plane and has a parachute attached, if it accelerates down
at 2m/s? what resistive force does the parachute supply?
Answer:
2340 N
Explanation:
There are two forces on the box. Weight force pulling down and resistive force pushing up.
Sum of forces in the y direction:
∑F = ma
F − mg = ma
F = mg + ma
F = m (g + a)
F = (300 kg) (9.8 m/s² + (-2 m/s²))
F = 2340 N

Most people can throw a baseball farther than a bowling ball, and most people would find it less painful to catch a flying baseball than a bowling ball flying at the same speed as the baseball. Explain these two situations in terms of a) Newton's first law of motion.
Complete question is;
Most people can throw a baseball farther than a bowling ball, and most people would find it less painful to catch a flying baseball than a bowling ball flying at the same speed as the baseball. Explain these two apparent facts in terms of
a.) Newtons first law of motion
b.) Newtons Second law of motion
Answer:
A) Explained below
B) Explained below
Explanation:
A) The statement given is that most people find it less painful catching a flying baseball than a bowling ball flying at the same speed as the baseball.
Newton's first law states that an object at rest will continue at rest or if in motion will continue in constant motion unless an external force acts on it.
This means that the velocity has to be constant and net force is zero.
It therefore means that people will need to apply plenty of force on the bowling ball with a constant velocity in order to maintain net force equal to zero.
B) Newton's second law of motion states that force is equal to the rate of change in momentum.
The given statement in the question is true because of the amount of mass and force needed to be applied.
Now, due to the fact that the bowling ball will require a lot of force to be applied on it, it will be hard for people to throw it easily. Thus, it will be easier for most people to throw the baseball than the bowling ball
An increase/decrease in which of the following variables would have the
greatest effect on the period of a simple pendulum?
We have no idea what those "following variables" are. You faded out right at the point where you were supposed to show them to us.
The period of a simple pendulum only depends on its length, and the acceleration of gravity in the place where the pendulum is swinging.
It's really tough to answer the question, because both of these things are in a fraction in the formula for the period . . . the length is the numerator, and the local acceleration of gravity is the denominator. So which one has a greater effect on the period really depends on what those numbers are before anything changes.

Answer:
The value of the charge is 6 c. Option c.
Explanation:
Electric Field
The electric field is defined as the force per unit charge that would experience a small positive test charge if held at some point in space.
The force F on a charge q at any point in space is equal to the product of the charge and the electric field E at that point .
[tex]F=q\cdot E[/tex]
Since we know the value of the electric field E=6\ N/c and the force F=36 N experienced by a certain charge q, we can solve the above equation for q:
[tex]\displaystyle q=\frac{F}{E}[/tex]
[tex]\displaystyle q=\frac{36\ N}{6\ N/c}[/tex]
q=6 c
The value of the charge is 6 c. Option c.
