Answer:
Mechanical advantage = 3
Explanation:
Mechanical advantage, MA = Output force/Input force
Output force = 15 N. Input force = 5 N
MA = Output force/Input force = 15 N/ 5 N = 3
Answer:
force and leverage distance
Explanation:
the formula for torque if = force x distance
(the distance above is the leverage distance on the crow bar)
therefore if there is an increase in either the torque or the leverage distance, or both, the torque exerted by the crow bar also increases.
for example
- lets assume a force of 5 n is applied on the crow bar with a leverage distance of 2 m.
the torque = 5 x 2 = 10 N.m
- but if the force was increased to 7 N
torque = 7 x 2 = 12 N.m
from the illustration above, we can see that the torque increased with an increase in force. There would also be an increase in torque if the distance were to be increased.
Refer to the diagram shown.

Define
Then the rate of change of h with respect to the vector v is
Answer: 17.7 ft per mile
A scientific theory states that the universe is expanding. the statement is correct about this theory is: d. it is a well supported explanation which cannot become law. a theory is very different from a law. a theory explain why something happen.
