Using a force of 28.0 Newton, a student pulls a 70.0 Newton weight along the tabletop for a distance of 15.0 meters in 3.0 secon

Musya8 [376]

Answer:

140 watt

Explanation:

We are given that

Force applied by student ,F=28 N

Weight pulled by students=70 N

Displacement,s=15 m

Time=3 s

We have to find the power developed by the student.

Work done=w= $F\times s$

Work done by the student= $28\times 15=420 J$

Power= $\frac{work\;done}{time}$

Using the formula

Power= $\frac{420}{3}=140watt$

Hence, the power developed by the students=140 watt

I threw a plastic ball in the pool for my dog to fetch. The mass of the ball was 125g. What must the volume be to have a density

Stells [14]

Answer:

250 mL

Explanation:

Density equation:

$Density = \frac{mass}{volume}$

Variables:

D = density

m = mass

V = volume

Solve:

M = 125 g

D = 0.500 g/mL

V = ?

$0.500 g/mL = \frac{125 g}{V}$

V = 250 mL
