Answer:
he longer ramp has more mechanical advantage for it requires less force to push up a mass while being over a longer period of time. Its called Mechanical Advantage because say you had to lift a car up 1-meter. you cannot simply pick it up, but over a long enough slope you would be able to because you can apply a small force over a longer distance
Explanation:
Answer:
The energy conversion does not fully occur due to various energy losses.
Explanation:
There are many different types of batteries, but all have three basic components: positive electrode (cathode, or "positive terminal"), negative electrode (anode or "negative terminal"), and electrolyte.
Charging a battery forces ions from cathode to anode; the battery reverses the flow. Over a period of time, this process wears out cathode, which results in reduced capacity.
Also there can be heat loss inside the system as well which is produced by the conversion from chemical energy.
Hence the chemical energy does not fully convert to electrical energy.
Explanation:
Given that,
Length of the spring, l = 50 cm
Mass, m = 330 g = 0.33 kg
(A) The mass is released and falls, stretching the spring by 28 cm before coming to rest at its lowest point. On applying second law of Newton at 14 cm below the lowest point we get :
(B) The amplitude of the oscillation is half of the total distance covered. So, amplitude is 14 cm.
(C) The frequency of the oscillation is given by :
