The radius of the planet Venus is nearly the same as that of earth, but it's mass is only 80% that of the earth.If an object weighs We on the earth , what does it weighs on Venus? Calculate the value of g on Venus

You hang a ball using a 0.240m long string to a window. You pull it at an angle of 22.0° and then release it. a. how much time does it take for the ball to reach its highest speed? b. how much time does it take if the pendulum is released at an angle 11.0°

Explain kg equation.

An electron is projected into a uniform electric field that has a magnitude of 500 N/C.

The direction of the electric field is vertically upward. The initial velocity of the

electron has a magnitude of 6.00 × 10^6 m/s, and its direction is at an angle of 30°

above the horizontal. Find:

I. The maximum distance the electron rises vertically above its initial elevation.

II. After what horizontal distance does the electron return to its original elevation.

Two forces And B acts at a point at right angles if their resultant is 50N and their sum is 70N calculate their magnitude

Newton’s Law of Gravitation says that the force of attraction between two objects is directly proportional to the product of their masses, and inversely proportional to the square of the distance between them:Define a gravitational field analogous to the electric field (force per unit charge), and derive Gauss’ Law for this

field using the properties of the Dirac Delta function in differential and integral form.

A pump discharges 700 𝑙𝑖𝑡𝑒𝑟𝑠 of fuel oil into a tank 25 𝑚 above the pump’s intake. How much work is done against gravity by the pump? One cubic centimeter of fuel oil has a mass of 0.89 g and one liter is 1, 000 𝑐𝑚3.
