A driver pushes on a car with a force of 8000 N for 15 seconds but is unable to move it. How much work is done
Answer:
the work done is zero.
Explanation:
Given;
applied force, F = 8000 N
time of force application, t = 15 s
Work done is given as the product of force and displacement. Since the car is unable to move, then the displacement is zero and the work done is zero.
Work done = Force x displacement
Work done = 8000 N x 0
Work done = 0
Therefore, the work done is zero.
Sloan is running with a momentum of 1850 kg m/s and has a mass of 58 kg. What is her velocity?
Answer:
v = 31.89 m/s
Explanation:
p = m × v
1,850 = 58 × v
58v = 1,850
v = 1,850/58
v = 31.89 m/s
Can someone please explain the conservation of momentum? I want to be a rocket scientist lol

which pair of chromosomes is the s3x chromosomes? Why?
Autosomes are homologous chromosomes i.e. chromosomes which contain the same genes (regions of DNA) in the same order along their chromosomal arms. The chromosomes of the 23rd pair are called allosomes consisting of two X chromosomes in most females, and an X chromosome and a Y chromosome in most males.

What is the charge of an electron and charge of neutron
Answer:
The charge of a neutron is 0
The charge of an electron is -1
Explanation:
Answer:
The charge of Neutrons is: 0
The charge of Electrons is: -1
Explanation:
Neutrons are uncharged and Electrons are negatively charged. The negative charge of one electron balances the positive charge of one proton. Both protons and neutrons have a mass of 1, while electrons have almost no mass.
what is the average acceleration of a car if a car rest from 0m/s and reaches a final velocity is 50m/s in 10m/s
Answer:
Assuming that you meant the final velocity of 50 m/s was reached in 10 s, the answer would be 5 m/s^2.
Explanation:
[tex]V_{f} = V_{i} + at[/tex]
So we update that with the values that we have.
[tex]50 = 0 +a(10)[/tex]
then simplify that using algebra to solve for a and we get 5 m/s^2

20. The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm). At this point water can be ______________. solid B. Liquid C. Gas D. All of the above E. None of the above
Answer:
E i think.
Explanation:
The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm. At this point water can be solid, liquid and gas. So, option (D) is correct.
What is phase diagram?phase diagram: a graph that displays the limiting conditions for a substance's solid, liquid, and gaseous phases under changes in pressure, temperature, or another combination of variables, such as solubility and temperature.
The curves in the figure were derived from measurements taken at various pressures and temperatures, and they represent a typical phase diagram for a one-component system (i.e., one made up of a single pure chemical).
What is triple-point?The combination of temperature and pressure at which a substance can exist in all three of its states—gas, liquid, and solid—is known as the triple point.
The Kelvin(K), the International System of Units' (SI) fundamental unit of thermodynamic temperature, is defined using the triple point of water. The triple-point of water occurs at 273.16 K (0.01 °C) and a vapor pressure of 0.0060373 atm.

Two magnets are held apart. Once released, the South Pole of one magnet moves toward the North Pole of another magnet until the magnets collide. How does the graph reflect the changes in energy that occur?
Answer:
Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.
Explanation:
easy
The increase in the kinetic energy occurs when both magnets are released.
Change in energy occurs between two magnets
The kinetic energy and velocity are at zero when the magnets are held apart from one another at a certain distance but the kinetic energy increases when they are released and move together so we can conclude that the increase in the kinetic energy occurs when both magnets are released.

Oh no! The Hulk just fell off the Empire State Building! Calculate how long it took him to fall straight down from the top of the Empire State Building, which is 380 m high.
If you can provide some, explanation I will greatly appreciate it.
Answer:

(but this is only if it's a free fall, which we assume since we didn't get the mass of the hulk)
Ill mark the brainliest pls lmk what answer ty
2800 m
Further explanationGiven
time = 80 s
average velocity = 35 m/s
Required
total distance before it broke down
Solution
Average velocity : total displacement : total time
Can be formulated
avg velocity = Δx : Δt
Input the value :
Δx=avg velocity x Δt
Δx = 35 m/s x 80 s
Δx = 2800 m
In addition, if we are asking for velocity, we must know the starting and ending points (displacement)
But if we calculate the total distance, what is written is the average speed
avg speed = total distance : total time

13. Harry used the energy stored in his muscles to cycle up a hill. What happened to this energy when he reached the top?
A. The energy stored in Harry's musclesbwas destroyed.
B. The energy was returned to Harry's muscles
C. Kinetic energy changed to potential energy.
D. Potential energy changed to kinetic energy.
Answer:
C. Kinetic energy changed to potential energy.
Explanation:
The kinetic energy is converted to potential energy when he reaches the top of the hill.
As with every system, energy is neither created nor destroyed but transformed from one form to another.
This is from the law of conservation of energy.
Kinetic energy is produced when Harry moves the up the hill. As he reaches the top of the hill and comes to rest, potential energy is formed.
Potential energy is the energy due to the position of a body.
