Three 14.05-g Styrofoam balls of radius 2 cm are coated with carbon black to create them conducting and then are tied to 1.23-m-long threads and suspended freely from a common point. Every ball is given the same charge, q. At equilibrium, the balls form an equilateral triangle with sides of length 20.64 cm in the horizontal plane. Decide the absolute value of q
Assume a black hole were to suck up a massive amount of surrounding oxygen and hydrogen. Would this ignite inside the black hole and turn it back into a star?
In a tornado, the pressure can be 15% below normal atmospheric pressure. Sometimes a tornado can move so rapidly that this pressure drop can occur in one second. Assume a tornado suddenly occurred outside your front door, which are 182 cm high and 91..
A 1.00 x 102-g mass of tungsten at 100.0°C is placed in 2.00 x 102 g of water at 20.0°C. The mixture reaches equilibrium at 21.6°C. Compute the specific heat of tungsten.
The cooling system of a car engine contains 20.0 Litre of water (1 L of water has a mass of 1 kg). Which is the better coolant, water or methanol? Describe.
A golf ball with mass 0.046 kg rests on a tee. It is struck by a golf club with an effective mass of 0.220 kg and a speed of 44 m/s. assuming that the collision is elastic, discover the speed of the ball when it leaves the tee.
Megan’s mass is 28 kilogram. She climbs the 4.8-m ladder of a slide and reaches a velocity of 3.2 m/s at the bottom of the slide. How much work was done with friction on Megan?
A 2.0-kg rock initially at rest loses 407 J of potential energy while falling to the ground. Compute the kinetic energy that the rock gains while falling. What is the rock’s speed just before it strikes the ground?
A 30.0-kg gun is resting on a frictionless surface. The gun fires a 50.0-g bullet with a muzzle velocity of 310.0 m/s. Compute the moment a of the bullet and the gun after the gun is fired.
A 2.00 x 103-kg car has a speed of 12.0 m/s. The car then hits a tree. The tree doesn’t move, and the car comes to rest. Find the change in kinetic energy of the car. Find the amount of work done in pushing in the front of the car.
Pam, wearing a rocket pack, stands on frictionless ice. She has a mass of 45 kg. The rocket supplies a constant force for 22.0 m, and Pam acquires a speed of 62.0 m/s.
