Hiii I need help solving those questions with steps as soon as possible please THANKYOUUU so much in advance !!!

Question #2 Describe the energy transformation in each of the following: 1. A light bulb is switched on. 2. An object is thrown vertically upward. 3. A stove is turned on 4. A car is speeding 5. Solar panelQuestion #6 Several friends use a simple rope and pulley to raise a tree house from the ground into a tree. The mass of the tree house is 150 Kg. By pulling together, the friends manage to exert an average force o 1600 N as they raise the tree house a distance of 3.2 m above the ground. a) Find the work done by the friends in raising the house. b) How much work done against gravity (Potential Energy) c) What is the work lost for friction d) Determine the efficiency of this pulley system e) Why the efficiency is not 100%a. the Potential Energy at the top of the hill. b. the Kinetic energy at the bottom of the hill c. the maximum speed reached at the bottom of the hill d. the total mechanical energy at the end of the horizontal road e. the NET Work on the level road f. the work done by the brake system g. the braking force h. the time needed to stop i. The Power of the brake system2. A tow truck pulls a car from rest onto a level road. The tow truck exerts a horizontal force of 1500 on the car. The friction force on the car is 810 N and the car moves forward 12 m. find: a) The work done by the tow truck b) The work done by the friction force c) The work done by the force of gravity d) The net work done e) The efficiency of the tow truckQuestion #4 A slid carrying two children (Total mass = 80 kg) sliding down a snow hill from a height 30 m above the level road reaches its maximum speed at the bottom of a hill, and then applies the brakes to stop in 20 m along a rough (has friction) horizontal road. Find 30 m 20m a. the Potential Energy at the top of the hill. b. the Kinetic energy at the bottom of the hillQuestion #5 mark'S 1. An electric water heater has a power rating of 2400 W. If the heater is turned on for 6 hours a day and the average cost of electricity is 8cent/KWh, find: a. The total amount of energy (in Joules) used per day. b. The total amount of energy (in KWh) used in one month (30 days) C. The cost ( in $ ) of operating this heater per month
