Answer:
B2 = 2.22mT
Explanation:
See attachment for the calculation.
Assuming the angle the magnetic field makes with the direction of current flow is the same in both cases and that the same current flows in both cases, then F1 = F2
See calculation below.
Answer:
liquid.
Explanation:
That is almost the definition of a liquid. So the answer is a liquid.
Answer:
The force to be applied on the primary piston is 140.63 N.
Explanation:
To solve this problem we apply the following formulas:
Pascal principle: F=P*A Formula (1)
F=Force applied to the piston
P: Pressure
A= Piston area
Formula (2)
d= piston diameter
Nomenclature:
Fp= Force on the primary piston
Fs= Force on the secondary piston
Ap= Primary piston area
As= Secondary piston area
W= car weight
Calculation of the force Fp necessary to support the weight of the car.
Pascal principle: Fp=P*Ap (Equation1)
In (Equation1) we know Ap and we don't know P.
Pressure calculation:
We apply Newton's first law for a balanced Secondary piston -automobile system
Newton's first law: ∑F=0
W-Fs=0
W=Fs
W=P*As

We replace
in equation 1:






Calculation of Fp in Newtons (N):


Fp=140.63N
