Answer:last choice is correct. Work is equally to force times distance
Explanation:to generalize, W is equal to to force as a function of distance integrated over distance. Work is equivilent to energy. See work/force equivalency
W=FdeltaD (Work is equal to Force multiplied by displacement.
F=W/delta D
F=2J/8m
F=0.25N
The sun dictates the direction of leaves and the direction that the plant will grow towards.
If a car crashes into another car like this, the wreck should go nowhere. Besides this being an unrealistic question, the physics of it would look like this:
Momentum before and after the collision is conserved.
Momentum before the collision:
p = m * v = 50000kg * 24m/s + 55000kg * 0m/s = 50000kg * 24m/s
Momentum after the collision:
p = m * v = (50000kg + 55000kg) * v
Setting both momenta equal:
50000kg * 24m/s = (50000kg + 55000kg) * v
Solving for the velocity v:
v = 50000kg * 24m/s/(50000kg + 55000kg) = 11,43m/s
Answer:
Below:
Explanation:
Food balance sheet data are useful in monitoring trends in food consumption over time and in making rough comparisons between countries. Often, such data are the only data that can be readily obtained for the rapid evaluation of new problems.
