<span>If you apply 100.0 N of force to lift an object with a single, fixed pulley, then the resistive force is also equivalent to 100 Newtons of force. Since the weight of the object was not mentioned, it is assumed that it has already been taken into account in the 100 N value of force. This follows Newton's law of motion of equal action and reaction.</span>
Answer:
avg speed =total distance/total time
total distance =2km (given)
total time=1/10 +1/25=7/50
so avg speed =100/7=14.28
Answer:
Final velocity= 84 m/s
Explanation:
V final= V initial + a * t
Vf = 0+ 12 (7)
Vf= 84 m/s
Charge is actually either excessive number or electrons or shortage of them.
as you can't destroy the electron or create it - you can't destroy or create charge
Answer:
d = 185.26 meters
Explanation:
It is given that,
Launching angle of the projectile, 
Initial speed of the projectile, u = 48 m/s
Let at distance d the projectile hits the ground from the launch point. It is equal to range of the projectile. Its formula is given by :
Substituting all the values in above formula. So, we get :
d = 185.26 meters
So, the distance between the launch point and the point where it hits is 185.26 meters. Hence, this is the required solution.
