Answer:
The magnitude of F when t=4 s=146.64 N
Explanation:
We are given that
Mass of crate,m=6.00 kg
Height of crate above its initial position is given by
We have to find the magnitude of F when t=4.00 s
Differentiate w.r.t t
Now, magnitude of force
Hence, the magnitude of F when t=4 s=146.64 N
Answer:
(a). The power delivered to the element is 187.68 mW
(b). The energy delivered to the element is 57.52 mJ.
Explanation:
Given that,
Charge
Voltage
Time t = 0.3 sec
We need to calculate the current
Using formula of current
Put the value of charge
(a).We need to calculate the power delivered to the element
Using formula of power
Put the value into the formula
Put the value of t
(b). We need to calculate the energy delivered to the element between 0 and 0.6 s
Using formula of energy
Put the value into the formula
Hence, (a). The power delivered to the element is 187.68 mW
(b). The energy delivered to the element is 57.52 mJ.
