Which of the following questions could best be answered by the work of warren Washington?
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).

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 .

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.
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.

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.

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

Which types of rocks can become metamorphic rock?
A. clastic sedimentary rock
B. both igneous and sedimentary rock
C. clastic or chemical sedimentary rock
D. both igneous and metamorphic rock
Answer:
i think the answer could be both B. and D. bc any type of rock can become a metamorphic rock with right conditions
Explanation:
A metamorphic rock, on the other hand, began as a rock—either a sedimentary, igneous, or even a different sort of metamorphic rock. Then, due to various conditions within the Earth, the existing rock was changed into a new kind of metamorphic rock.
Answer:
B.) Both Igneous and Sedimentary rock
Explanation:
Since Metamorphic rocks can form from either Igneous or Sedimentary rocks. Since the sedimentary particles from which sedimentary rock is formed can be derived from a metamorphic, igneous, or another sedimentary rock, all three rock types can be melted to form magma.
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.

A Penny is dropped and falls freely from the top of the Empire State building 443m high. What information do you know? 1b. How long does it take to hit the ground? 1c. How fast is it moving right before it hits the ground?
Answer:
1b. 9.51 s
1c. 93.18 m/s.
Explanation:
1a. From the question given above, the following data were obtained:
Initial velocity (u) = 0 m/s
Height (h) = 443 m
Acceleration due to gravity (g) = 9.8 m/s²
1b. Determination of the time it takes for the penny to get to the ground.
Height (h) = 443 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =?
h = ½gt²
443 = ½ × 9.8 × t²
443 = 4.9 × t²
Divide both side by 4.9
t² = 443/4.9
Take the square root of both side
t = √(443/4.9)
t = 9.51 s
1c. Determination of the speed of the penny before it hits the ground.
Initial velocity (u) = 0 m/s
Height (h) = 443 m
Acceleration due to gravity (g) = 9.8 m/s²
Final velocity (v) =.?
v² = u² + 2gh
v² = 0² + 2 × 9.8 × 443
v² = 0 + 8682.8
v² = 8682.8
Take the square root of both side
v = √8682.8
v = 93.18 m/s
