So I think it’s D. So you’ll do 5 x 5 x 5 = 125 then x 2 = 250
Question 2 would be 6+3+n=12
Power is work done per time and work done is force times distance. The power is found by multiplying the force(20N) and the distance(5m) and dividing the product by the time(5s)
(20*5)/5=20Nm/s OR 20 watts.
Therefore the power needed is 20 watts.
Answer: 5 mile per per hour.
Step-by-step explanation:
=
1/25x = 1/5
x= 5
