A cook plugs a 1000 W crockpot and a 400 W kettle into a 240 V power supply, all operating on directc When we compare the two, we find that

Madison pushes with a 210-n horizontal force on a 24-kg crate of coffee resting on a warehouse floor. the force of friction on the crate is 74 n. what is the acceleration?

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

Aturntable that spins at a constant 74.0 rpm takes 3.10 s to reach this angular speed after it is turned on. find its angular acceleration (in rad/s2), assuming it to be constant, and the number of degrees it turns through while speeding up.
