A constant magnetic field passes through a single rectangular loop whose dimensions are 0.41 m x 0.65 m. The magnetic field has

a magnitude of 1.8 T and is inclined at an angle of 78° with respect to the normal to the plane of the loop.
(a) If the magnetic field decreases to zero in a time of 0.63 s, what is the magnitude of the average emf induced in the loop?
(b) If the magnetic field remains constant at its initail calue of 2.1T, what is the magnitude of the rate ΔA/Δt at which the area should change so that the average emf has the same magnitude as in part (a)?

A student throws a ball upward with a velocity of 35 m/s. What is the acceleration of the ball as it rises to the top of its arc
lora16 [44]

Answer:

The acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.

Explanation:

Let suppose that maximum height of the arc is so small in comparison with the radius of the Earth.

Since the ball is launched upwards, then the ball experiments a free-fall motion, that is, an uniform accelerated motion in which the element is accelerated by gravity. Then, the acceleration experimented by the motion remains constant at every instant and position.

Besides, the gravitational acceleration in the Earth and, in consequence, the acceleration of the ball as it rises to the top of its arc equals 9.807 meters per square second.

Calculating Velocity
m_a_m_a [10]

The average velocity of the object represented by the  distance time graph is 0.1\:meter\:per\:second

  • The velocity of an object is the change in the distance moved by an object with time.

  • This could also be related to the rate of change or slope of the graph.

  • Average velocity = \frac{change\:in\:distance}{change\:in\:time}

  • Average velocity = \frac{(5-0)}{(50-0}) = \frac{5}{50}=0.1\:meter\:per\:second

Therefore, the average velocity of the object is 0.1\:meter\:per\:second

The “turning effect of a force” (T = F * r) is:
Doss [256]

Answer:

b and e

Explanation:

r x F is the formula for torque.

The "turning effect" or torque happens when concentric forces rotate an object along said center.

a) False because T = Fr = Ia (a = angular acceleration)

b) True

c) False. L = Iw (w = angular velocity), which does not equal Ia

d) False. It is torque, not the product of torque and something else

e) True.

How to find input force ​
vfiekz [6]

Answer: Calculate the work input in a pulley by using the previous readings in the correct mathematical equation. : Work (W) equals force (f) multiplied by distance (d), or W=fd. The work done by the pulley is the equation of weight (w) multiplied by height traveled (h).
