Answer:
Explanation:
Pascal's law states that when there is an increase in pressure at any point in a confined fluid, the pressure is equally distributed at every other point in the container.
The formulas that relate to this are given below:
P1 = P2 (since the pressures are equal throughout).
P2 is the pressure transmitted in the hydraulic system
N.B : P= Force/ Area
Therefore we have
F1/A1 = P2
F1= the force exerted by the driver = 100N
P2= 100/A1 N/m² or 100/A1 pa or 100/(101325× A1) atm
Answer:
B = 4 T
Explanation:
We have,
Length of a wire is 1 m
The wire is placed at an angle of 30 degrees with uniform magnetic field. It is required to find the strength of magnetic field. The force acting on a wire in magnetic field is given by:
So, the strength of magnetic field is 4 T.
Answer:
A mass of 4 Kg rest on the horizontal plane. The plane is gradually inclined until at an angle of θ=15
∘
with the horizontal,the mass just being to slide what is the coffeficient of static friction between the block & the surface.
Explanation:
Momentum = mass x velocity
So both mass and velocity affect an object's momentum.
Answer:
A
Explanation:
warm air rises creating low presure
cold air sinks creating high presure
so this means that temprature is realated to presure.
