HELP PLZ 1) A person wants to move a table from one side of the room to the other. The room is 15 meters across. If that person supplies a constant force of 500 N while pushing the table, how much energy will it take them to move it?

2)A person pushed a shopping cart down an aisle at the grocery store. The entire time that person supplied a constant force of 10 N on the cart. That person did 200 J of work pushing it from one end of the aisle to the other. How long was the aisle?

3) A car is driving down the road. What type of energy is stored in the motion of the car?

4) A person has a mass of 85 kg and is in a building 75 meters high. What is the person’s gravitational potential energy? (g = 10 m/s2)

5) A picture with a mass of 3 kg is sitting on a shelf. Its gravitational potential energy is 60 J. How is high is the shelf?

6) An astronaut with a mass of 50 kg is standing on top of a cliff on Mars. The cliff is 20 meters high, and her gravitational potential energy is 3,700 J. What is the value of “g” on Mars?
(g = acceleration due to gravity)

7) A spring with a spring constant of 200 N/m is pulled with a force of 400 N. How far will the spring extend?

8) A spring is pulled with a 100 N force causing it to extend 0.5 meters. What is the spring's spring constant (k)?

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
