The answer would be the coulombs law.
Answer:
7212.3 N
Explanation:
F = 7.38 x 10^4 N, v = 36.2 m/s
Let b be the strength of magnetic field and charge on the particle is q.
F = q v B Sin theta
Here theta = 90 degree
7.38 x 10^4 = q x 36.2 x B x Sin 90
q B = 2038.7 .....(1)
Now, theta = 17 degree, v = 12.1 m/s
F = q v B Sin theta
F = 2038.7 x 12.1 x Sin 17 ( q v = 2038.7 from equation (1)
F = 7212.3 N
Force (N) = mass (kg) × acceleration (m/s²)
Answer: crystals
Explanation: intrusive igneous rocks are formed by slow cooling magma which contain crystals
Power is defined as the amount of work over a certain amount of time. Work is also Force times the distance traveled. Simplifying the expression makes it Power=Force x Velocity. Since we are given that the power is 4500 W and the force is 100 N, dividing the Power by force gives 45 m/s, which is the velocity of the ball.
