The answer is gravity. I hope this helps.
The time must be measured with respect to gravity. As it falls, it has free fall that is the force acting on it will be the gravity.With the distance in account, d = 1/2 gt²
t = √(2d/g)
Answer:
the power of the solar cell is 1.5 watts
Explanation:
Recall that power is defined as the product of the voltage (V) times the running current (I): Power = V * I.
The only thing we have to take care of before actually performing the operation, is to convert milliamps into Amps, so our answer comes directly in the appropriate units (Watts). 500 mAmps can be written as 0.5 Amps, then, the product becomes:
Power = V * I = 3 V * 0.5 Amps = 1.5 watts
Answer:
The distance covered by the balloon is 47.52 meters.
Explanation:
Given that,
Initial speed of the balloon, u = 1.14 m/
Let us assumed we need to find the distance covered by the balloon after t = 3 second. Let d is the distance covered by the balloon. It can be given by :
![d=ut+\dfrac{1}{2}at^2](https://tex.z-dn.net/?f=d%3Dut%2B%5Cdfrac%7B1%7D%7B2%7Dat%5E2)
Here, a = g
![d=ut+\dfrac{1}{2}gt^2](https://tex.z-dn.net/?f=d%3Dut%2B%5Cdfrac%7B1%7D%7B2%7Dgt%5E2)
![d=1.14\times 3+\dfrac{1}{2}\times 9.8\times (3)^2](https://tex.z-dn.net/?f=d%3D1.14%5Ctimes%203%2B%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%209.8%5Ctimes%20%283%29%5E2)
d = 47.52 meters
So, the distance covered by the balloon is 47.52 meters. Hence, this is the required solution.
