A 0.45 kg soccer ball changes its velocity by 20.0 m/s due to a force applied to it in 0.10 seconds. What force was necessary fo
frutty [35]

Answer:

90 N

Explanation:

The force applied to the ball is given by:

F=\frac{\Delta p}{\Delta t}

where

\Delta p is the change in momentum of the ball

\Delta t is the time taken

The change on momentum of the ball is:

\Delta p=m\Delta v=(0.45 kg)(20 m/s)=9 kg m/s

So, the force applied is

F=\frac{9 kg m/s}{0.10 s}=90 N

A 16.0 Ω, 13.0 Ω, and 7.00 Ω resistor are connected in parallel to an emf source. A current of 6.00 A is in the 13.0 Ω resistor.
Darya [45]

Answer:3.54ohms

Explanation: connection in parallel

1/Rt= 1/R1+1/R2+1/R3

1/Rt= 1/16+1/13+1/7

1/Rt= 91+112+208/1456

1/Rt= 411/1456

411Rt= 1456

Rt= 1456/411

Rt= 3.54ohms
