Answer:
0.0025116weber/m²
Explanation:
Magnetic field density (B) is the ratio of the magnetic flux (¶) through the loop to its cross sectional area (A).
Mathematically;
B = ¶/A
¶ = BA
Given B = 0.23Tesla which is the magnitude of the magnetic field
Dimension of the rectangular loop = 7.8 cm by 14 cm
Area of the rectangular loop perpendicular to the field B = 7.8cm×14cm
= 109.2cm²
Converting this value to m²
Area of the loop = 109.2 × 10^-4
Area of the loop = 0.01092m²
Magneto flux = 0.23×0.01092
Magnetic flux = 0.0025116weber/m²

Newton's second law of motion:
F=ma
You convert from km/h to m/s by dividing by 3.6:
Then a is:
Then:
F=(980)(2.8)=2744 N
Answer:
V = 5.96 m/s
Explanation:
First we find the force required to move the car up the inclined plane. This force shall be equal to the component of the weight of the car that is parallel to the inclined plane. Hence,
F = W Sin θ
F = mg Sin θ
where,
F = Force = ?
m = mass of car = 1600 kg
g = 9.8 m/s²
θ = Inclination Angle = 20°
Therefore,
F = (1600 kg)(9.8 m/s²) Sin 20°
F = 5362.87 N
Now, we use power formula:
P = FV
V = P/F
where,
P = Engine Power = 32000 W
V = Maximum Velocity of Car = ?
Therefore,
V = 32000 W/5362.87 N
<u>V = 5.96 m/s</u>
