B2 If a rectangular coil, with length ofa and height of V3a ( = 1m), is rotating at an angular velocity, o -50 rad/s, in a B-field. At the starting position, the plane of the coil is exactly normal to the B-field as shown in Fig. B2a (1) What is the induced e.m.f. in the coil? (in V) (4 marks) (2) What is the induced e.m.f. if the starting position is paralleled to the B-field as (4 marks) shown in...
The system is initially moving with the cable taut, the 10-kg block moving down the rough incline with a speed of 0.130 m/s, and the spring stretched 25 mm. By the method of this article, (a) determine the velocity v of the block after it has traveled 108 mm, and (b) calculate the distance d traveled by the block before it comes to rest. 10 kg >K= 155 N/m Up = 0.18 7 460 Answers: (a) After it has traveled...

need a clear explanation.. thank u
Question 3 (10 Marks) If block A in Figure is moving downward at speed VA=6 ft's while block C is moving down at speed Vc= 3 VA, determine the relative velocity of block B with respect to C. B А
A 3020 kg demolition ball swings at the end of a 37.0 m cable on the arc of a vertical circle. At the lowest point of the swing, the ball is moving at a speed of 1.76 m/s. Determine the tension in the cable.
A fire helicopter carries a 967 kg bucket at the end of a cable 19 m long as in the figure. As the helicopter flies to a fire at a constant speed of 50 m/s, the cable makes an angle of 4dº with respect to the vertical. The bucket presents a cross sectional area of 6.03 m in a plane perpendicular to the air moving past it. Use 1.2 kg/m for the density of air. The acceleration of gravity is...
please! help me understand how to solve this problem.

Assume each layer has negligible thickness. -Q bt Fig. Bla Fig. Blb (1) Find the electric field intensity E (p) and potential difference in...
A 0.5 kg ball connected at the end of a 3 m cable is whirled in a vertical circle at the same constant speed of 2 m/s. Determine the tension in the cable: a) at the lowest point of the swing b) at the highest point of the swing C) at the far left or far right points of the swing
A block having a mass of 5 kg
is initially moving at a speed of 10 m/s in the positive
x-direction when it experiences a head on collision with a second
block having a mass of 8 kg that was initially moving in the
negative x-direction with a speed of 3 m/s. After the collision the
velocity of the larger, 8 kg, block is observed to be 5 m/s in the
positive x-direction. The situations before and after the collision...
pls help
Question 2 (a) Fig. Q2a shows a 1.8 kg block A placed in front of a compression spring, initially compressed by 40mm from its neutral position. Given that the spring constant k= 6000 N/m and the kinetic coefficient of friction between block (A) and the floor is pk = 0.1. The block A is released from rest and travels towards the right Compression Spring 40 mm wwww! A 00 Fig. 2a Determine the velocity of the block when...
