The distance from Venus to the center of the sun is 0.722 times that of earth. How many years does it take for Venus to orbit the sun?

An object has a mass of m and weight of w on earth. Suppose a new planet was discovered whose mass is one-tenth that of earth and whose radius is one-fifth that of earth. What is the mass and weight of the object on the new planet?

Imagine a sound wave with λ = 1.33 m and f = 256 Hz that is travelling through the air. If it strikes a brick wall, compare the frequency, wavelength, and phase angle of the sound wave that is reflected and the sound wave that penetrates the wall to that of the original wave.

A pendulum is in simple harmonic motion with maximum angle θ, height h above equilibrium at angle θ, length L, and period T. Show work to explain your answer.

What is the period of this pendulum in terms of T if it was taken to Mars? (g(subscript)mars = 2.6 times less than Earth)

A block (m = 7.50 kg) is attached to a spring (k = 285 N/m) and placed on a frictionless surface. The block is displaced 18.0 cm to the left of its equilibrium position and released at time = 0. Where is the block at 0.625 sec? Don’t forget to include left or right of equilibrium position. Show work to explain your answer.

Neglecting friction and the mass of the string, what is the acceleration experienced by m2 when m2 is 20.0 kg and m1 is 20.0 kg? Also, what are the tensions on each box and what is the angular acceleration of the pulley (m = 1.00 kg and r = 10.00 cm).

m1 is on a flat surface and m2 is hanging off the side of the platform.

A mass slides down an incline that has an angle of 35.0° relative to the horizontal. The height of the incline is 2.00 m, and the mass is initially at rest. Neglect friction.

What will be the speed at the bottom of the hill? Show your work.

An charged particle with a charge of 3.0 C is pushed toward a stationary charge of 9.0 C. The charged object is initially very far away from the stationary object. After 500.0 seconds the objects are 0.250 m apart.

A mass is sliding down an incline. If we were to increase the angle of elevation for the incline, the magnitude of the component of its weight perpendicular to the incline _______.

A: increases.

B: decreases.

C: decreases then increases.

D: does not change.

E: increases then decreases.
