C I think the answer is true
Answer:
F = I L X B = I L B sin theta
F = 5.2 * 1.2 * .87 sin 45 = 3.84 N in the direction of (L X B)
Note: L and B must be at right angles for F = I L B
The kinetic energy of an object that has a mass of 50.0 kg and a velocity of 18m/s is 8,100J.
<h3>KINETIC ENERGY:</h3>
Kinetic energy refers to the energy of a body due to its motion. The kinetic energy can be calculated as follows:
K.E = ½ m × v²
Where;
- K.E = kinetic energy (J)
- m = mass (kg)
- v = velocity (m/s)
According to this question, an object that has a mass of 50.0 kg and a velocity of 18m/s. The kinetic energy can be calculated as follows:
K.E = ½ × 50 × 18²
K.E = ½ × 16,200
K.E = 8100J.
Therefore, the kinetic energy of an object that has a mass of 50.0 kg and a velocity of 18m/s is 8,100J.

Answer:
2m
Explanation:
The Force of a spring = Spring Constant,K × extension
Hence extension or stretch = 400/200= 2m
