Ablock sits at rest on a table, 0.9 m above the ground. if the black has a six j of energy (with the ground set as zero height level), what is the mass of the block?

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) .

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

The charge on a charged sphere is: a)concentrated at its centerb)distributed uniformly throughout its volumec)clustered on its centerd)distributed uniformly over its surface
