Antonio (883 N) does a push-up lifting his body a total of 0.6 meters (down and back up). If this process generated 375 Watts of power, how long did it take her to complete the push-up?

Time = 1.413 seconds.

Explanation:

Given the following data;

Force = 883N

Distance = 0.6m

Power = 375 Watts

To find the time;

First of all, we would find the work done by Antonio.

Workdone = force * distance

Workdone = 883 * 0.6

Workdone = 529.8 Joules.

Now, to find the time;

Time = workdone/power

Substituting into the equation, we have

Time = 529.8/375

Time = 1.413 seconds.

Therefore, it took her 1.413 seconds to complete the push-up.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
