Which astronomer gave his name to a telescope launched into space in 1990?

There is an electric field in the region between the two plates. The magnitude of this electric field is ed. This imposes another condition on the charge densities on the surfaces of the plates. How can this condition be expressed?

a ball is thrown at a 30 angle above the horizontal across level ground. it is released from height of 2.00 m above the ground with a speed of 24.0m/s. how far does the ball travel horizontally before it strikes the ground?

A weight lifter lifts a set of weights a vertical distance of 2.00 m. If a constant net force of 350 N is exerted on the weights, what is the work done by the lifter on the weights?

You leave the doctor's office after your annual checkup and recall that you weighed 688 N in her office. You then get into an elevator that, conveniently, has a scale.

Identify the machines in which both a lever and a wedge are used

What happens to an object if the forces acting on it are unbalanced?

A 92-kg astronaut and a 2000-kg satellite are at rest relative to a space station. the astronaut pushes on the satellite, giving it a speed of 0.14 m/s directly away from the station.

How to calculate wavelength in m when you know the frequency?

Ball A has a mass of 0.200 kilograms. Ball A, traveling at a velocity of 2 meters/second in the + x direction, hits a stationary ball B of the same mass. After the collision, ball B bounces off at a positive angle with respect to the + x-direction.

10. If the wavelength of the light is decreased, the width of the central maximum in the diffraction pattern will B) increase A) decrease C) remain the same
