Which statements describe velocity and acceleration? check all that apply. velocity equals displacement divided by time. all velocities are “instantaneous” and occur only at a point in time. velocity and acceleration are calculated using the same variables. acceleration equals change in velocity divided by time. acceleration is always constant; it cannot vary. average velocity can be found by using several velocities and their total time.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

Discuss how the hardness or softness of the landing surface is related to the time required to stop the egg

Both speed and velocity measure how fast something is moving. however, since speed is not a it does not require a(n question 6 options: a) quantity , unit b) magnitude, unit c) scalar, direction d) vector, direction
