Answer:
(A) Total energy will be equal to
(b) Energy density will be equal to
Explanation:
We have given diameter of the plate d = 2 cm = 0.02 m
So area of the plate
Distance between the plates d = 0.50 mm =
Permitivity of free space
Potential difference V =200 volt
Capacitance between the plate is equal to
(a) Total energy stored in the capacitor is equal to
(b) Volume will be equal to , here A is area and d is distance between plates
So energy density
Answer:
180.4 m
Explanation:
The package in relation to the point where it was released falls a certain distance that is calculated by applying the horizontal motion formulas , as the horizontal speed of the plane and the height above the ground are known, the time that It takes the package to reach its destination and then the horizontal distance (x) is calculated from where it was dropped, as follows:
h = 100 m
x =?
Height formula h:
Time t is cleared:
t = 4.51 sec
Horizontal distance formula x:
x = 40 m / sec x 4.51 sec
x = 180.4 m
Given :
A box weighing 12,000 N is parked on a 36° slope.
To Find :
What will be the component of the weight parallel to the plane that balances friction.
Solution :
The component of that will be parallel to the plane to balance friction is :
Therefore, component of force to balance friction is F sin 36° .
Hence, this is the required solution.
