as we need to pull up a box of weight 200 N
now by above formula we can find how much force it requires to pull up the box
so it requires 50 N force to pull the weight of 200 N
Answer:
The maximum power delivered by the power supply is 0.81 W.
Explanation:
Given that,
Inductance L= 2.0 H
Resistance R = 100 ohm
Voltage = 9.0 V
We need to calculate the power
Using formula of power
Where, P = power
V = voltage
R = resistance
Put the value into the formula
Hence, The maximum power delivered by the power supply is 0.81 W.
Answer:
the energy of groud state =
Explanation:
the energy of a 3 dimensional rectangular box is given by
where h is planks constant m is the mass of the particle ,
and
are principal quantum number in x y and z direction. and
,
and
are length of box in x y and z direction.
therefore the energy of ground state will be when ,
and
= 1
therefore energy of ground state =
=
