Answer:
The pressure remains the same.
F = P * A the amount of force transmitted would double if only the input area is changed. Pressure is the same at all points in the system.
Force of a crate : 300 N
<h3>Further explanation</h3>
Given
0.25 meters wide and 1.5 meters long
Pressure = 800 Pa
Required
Force
Solution
P = F/A
A = 0.25 x 1.5
A = 0.375 m²
P = 800 Pa = 800 N/m²
Input the value :
F = P x A
F = 800 N/m² x 0.375 m²
F = 300 N
Answer:
500 kW
Explanation:
Given that,
Energy of the train, E = 2 MJ = 2×10⁶ J
Time, t = 4 seconds
We need to find the power of the train. We know that,
Power = energy/time
So,

So, the power of the train is equal to 500 kW.
A large organelle called a vacuole fills with water and pushes on the cell wall to give it a rigid shape. The amount of pressure exerted by the vacuole is called "turgor pressure".
the potential at the center of curvature of the arc = v = Q ∕ (4πε∘a) or 
ATQ,
We have density of charge,
λ = 
Where L is the rod's length, in this case the semicircle's length L = πr
Q is the charge on the rod
The potential created at the center by an differential element of charge is:

where k is the coulomb's constant
r is the distance from dQ to center of the circle
v = ∫
, Where a = radius, k = 1 / 4πε∘
v =
or Q ∕ (4πε∘a)
