Find the magnitude of the gravitational force exerted on a 66.5 kg astronaut on the surface of planet x if the planet has a radius of 4.40 x 10⁶ m and a mass of 8.43 x 10²³ kg. (use g= 6.67 x 10⁻¹¹ nm/kg²)

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.

Awave that is traveling fast can be said to have a high a. frequency b. speed c. wavelength d. amplitude e. period f. none of these
