An elevator releases 10,000 j of gravitational potential en-ergy while descending 5 m between fl oors. how much does the elevator weigh?

Consider the acceleration graph. If the mass of the object that is accelerating does not change, but the force applied is tripled, how would the slope of the line change?

Give relation between potential work and time

Now that we have a feel for the state of the circuit in its steady state, let us obtain the expression for the current in the circuit as a function of time. Note that we can use the loop rule (going around counterclockwise) : E-vR-vL=0.

The lowest level of stimulation that a person can consciously detect 50 percent of the time the stimulation is present is called what?

In answering the following questions, assume that the angular acceleration is constant and nonzero:?0. Suppose you are asked to find the amount of time t, in seconds, it takes for the turntable to reach its final rotational speed.

For each case, identify the force (including its direction) that causes the acceleration. (a) A sprinter at the very start of the race.

Select the effects of radiation below that are stochastic: associated with short-term, high-level exposure associated with long-term, low-level exposure include cancer and other DNA mutation include burns and radiation sickness

On the modern periodic table, elements are ordered according to what?

Jack drops a stone from rest off of the top of a bridge that is 24.4 m above the ground. After the stone falls 6.6 m, Jill throws a second stone straight down. Both rocks hit the water at the exact same time.

How is Electric current able to flow?
