Faraday's Law of Induction

A single conducting loop of wire has an area of 7.53E-2 m^2 and a resistance of 106 ohms. Perpendicular to the plane of the loop is a magnetic field strength 0.158 T. At what rate (in T/s) must this field change if the induced current in the loop is to be 0.225 A?

work done by a constant force.

I think i have both answers, but i really need (b) explained. " You go to a pumpkin patch to select your Halloween pumpkin. You lift the 3.2kg pumpkin to a height of 1.2 m, then carry it 50.0 m on level ground to the checkout stand. (a) calculate the work you do on the pumpkin as you lift it from the ground, and (b) how much ...continues

Verify if the mathematics from my kinetic entity ring matches the equations Einstein's theory of relativity

I have come up with the hypothesis of the existence of a kinetic entity ring that can explain the physics behind Einstein's theory of relativity. I have posted my theory in my webpage at www.sc-innovation.com/entity.html. I am not a mathematician and so cannot mathematically verify if the mathematics from this kinetic entity rin ...continues

mathematical equation for my kinetic entity ring

I have come up with the hypothesis of the existence of a kinetic entity ring that could explain the physics behind Einstein's theory of relativity. I have posted my theory in my webpage at www.sc-innovation.com/entity.html. I am not a mathematician and so cannot come up with the equation for my kinetic entity ring. I hope someo ...continues

potential energy and conservative forces

1. A 1.9-kg block slides down a frictionless ramp. The top of the ramp is 1.5 m above the ground; the bottom of the ramp is 0.25 m above the ground. The block leaves the ramp moving horizontally, and lands a horizontal distance d away. Find the distance d. 2. Suppose the ramp is not frictionless. Find the distance d for ...continues

ball rolling in a cone

42. Consider a ball rolling around in a circular path on the inner surface of the cone. The weight of the ball is shown by the vector W. Without firction, only one other force acts on the ball-a normal force. (a) draw in the normal vector (how long depends on b). (b)Using the perallelogram rule, show that the resultant of the t ...continues

physics problem

Suppose the pendulum bob above has a mass of 0.33kg and is moving to the right at point b with a speed of 2.4 m/s. (a.) What is the bob's kinetic energy at point B? (b) At some point the bob will come to rest. Without doing an additional calculation, determine the change in the systems gravitational potential energy at the poi ...continues

physics problem

I have all the answers to the problem, but i need someone to explain to me exactly how the ansewer to (c)in obtained, with an in depth explanation as to how to find the maximum angle the string makes with the vertical as the bob swings back and forth.

magnitude and direction of a object

Determine trigonometrically the magnitude and direction of the velocity of a plane that is flying west at 100.0km/h with respect to the air while the wind is blowing toward the north at 65.0 km/h relative to he ground.

the highest position the car reaches at the bottom of the hill

A 750 kilogram automobile is moving at 20.0 meters per second at a height of 5.0 meters above the bottom of the hill when it runs out of gasoline. The car coasts down the hill and then continues coasting up the other side unitl it comes to rest. Ignoring frictional forces and air resistance, what is the value of "h", the highes ...continues
