I believe that a light bulb releases visible light and a radio antenna releases a radio waves
mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as


2) when speed is 3 m/s
kinetic energy is given as


3) when speed is 4 m/s
kinetic energy is given as


4) when speed is 5 m/s
kinetic energy is given as


5) when speed is 6 m/s
kinetic energy is given as


In series connection in orde to find the total resistance we add all the resistance capacity but in parallel, we take the 1/R and resistance = V hence the series connection takes up more power,
Answer:

Explanation:
= radius of the loop
= mass of the block
= speed of the block at top of the loop at point A
= magnitude of acceleration of block at A
At point A, the block moves in a circle and hence experience centripetal force. Due to this centripetal force, the centripetal acceleration of the block can be given as
