Answer:
333 N
Explanation:
The weight of an object is given by:
where
m is the mass of the object
g is the acceleration of gravity
For the mower in the problem,
m = 34 kg
Also
So, the weight of the mower is
Answer:
Force that the output plunger applies to the car; F2 = 3888N
Explanation:
For a hydraulic device, the relationship between the force and the area using Pascal's principle is;
F1/A1 = F2/A2
Where;
F1 is force applied to the input piston
F2 is force that the output plunger applies to the car
A1 is Area of input piston
A2 is area of larger piston
We are given;
R2/R1 = 9
So,R2 = 9R1
F1 = 48N
Area of input piston;
A1 = π(R1)²
Area of output piston;
A2 = π(9R1)²
Since, (F1/A1) = (F2/A2)
Thus;
F1/(π(R1)²) = F2/(π(9R1)²)
If we simplify, π(R1)² will cancel out to give;
F1 = F2/9²
Thus;
F2 = 9² x F1
Plugging in 48N for F1, we have;
F2 = 9² x 48
F2 = 81 x 48
F2 = 3888N
Answer:
C. 0.25J
Explanation:
Energy stored in the magnetic field of the inductor is expressed as E = 1/2LI² where;
L is the inductance
I is the current flowing in the inductor
Given parameters
L = 20mH = 20×10^-3H
I = 5A
Required
Energy stored in the magnetic field.
E = 1/2 × 20×10^-3 × 5²
E = 1/2 × 20×10^-3 × 25
E = 10×10^-3 × 25
E = 0.01 × 25
E = 0.25Joules.
Hence the energy stored in the magnetic field of this inductor is 0.25Joules
