If a textbook weighs 19.6n on earth. what is its mass?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.

What is the power rating of the lightbulb if 3.0 a flow through it when connected to a 15 v battery
