How much kinetic energy is in a punch thrown at 30 m/s? The fist and arm weighs 6 lbs. (1 lb = 2.2 kg)

Assuming that all of the carbon dioxide ends up in the balloon, what will be the volume of the balloon at a temperature of 27 ∘C and a pressure of 742 mmHg?

Two objects gravitationally attract with a force of 10N. If the distance between the two objects center is doubled, then the new force is

a superconducting solenoid is to be designed to generate a magnetic field of 10 t if the solenoid winding has 2000 turns meter what is the required current

onsider a half-wave rectifier circuit with a triangular-wave input of 5-V peak-to-peak amplitude and zero average, and with R = 1 k?. Assume that the diode can be represented by the constant-voltage-drop model with VD = 0.7 V.

A plane moves at a certain velocity and then it accelerates at the rate of 52m/s for a distance of 2300m to reach a velocity of 620m/s. how fast the plane going before it began to accelerate

Why does a charged balloon stick to a neutral wall?

While the cart is moving along an aisle, it comes in contact with a smear of margarine that had recently been dropped on the floor. Suddenly the friction force is reduced for - 40.0 newtons to - 20.0 newtons.

When a solo eclipse occurs. It is seen in
