Answer:
You would have to find the friction force of the rubber block which would be found with the equation of Normal force (mass*gravity) times cooeficient of friction which would give 8.82 N for the amount of friction and because you need more force than 8.82 N (assuming gravity is 9.8)
Answer: 166.67km/hr
Explanation:
Given the following :
Distance traveled = 250km
Time taken = 1.5 hours
Recall :
Speed = Distance traveled / time taken
Speed = 250 km / 1.5 hours
Speed = 166. 67 km/hr
Speed in m/s:
166.67km/hr = (166.67 × 1000)m / 3600 s
= 166670m / 3600s
= 46.3m/s
The current intensity is defined as the amount of charge flowing through a certain point of a wire divided by the time interval:

where Q is the charge and

is the time. Re-arranging the formula, we have

for the compressor in our problem, the intensity of current is I=66.1 A, while the time is

, so the amount of charge that crosses a certain point of the circuit during this time is
