To find max torque you need component of force that is perpendicular to the direction of vector r. For second part just set the equation above equal to 2308 and solve for Fmax. Only difference is the angle
Energy needs, in total kilocalories per day, are greater during adolescence than any other time of life. The correct option among all the options that are given in the question is the second option or option "b". Only during the time of pregnancy will a girl require more kilocalories per day than during the time of adolescence.
Answer:A
Explanation:
Kinetic energy is energy caused by motion.a body in motion possess kinetic energy
100N divide 2 by 200 it is 100
Answer:
Average speed = (2x+3y)/5 miles/hour
Explanation:
Average speed is the total distance travelled per unit time.
Average speed = total distance/total time taken
Given;
1. Travelled x miles per hour for 2hours.
2 travelled y miles per hour for 3 hours.
Distance covered is;
1. Distance = speed × time
d1 = x × 2 = 2x
2. d2 = y × 3 = 3y
Total distance travelled = d1+d2 = 2x + 3y
Total time taken = t1+t2 = 2+3 = 5hours
Average speed = (2x+3y)/5 miles/hour
