Answer:
Answer: Say the big boy is 40kg and the small boy is 20kg... ... ...then by the rule that moments around a fulcrum or pivot should be equal for equilibrium, the distance of big boy from pivot=half of dist of small boy from pivot
Answer with explanation:
We know that when we weigh ourselves on a scale the scale measures the Reaction force that acts between the scale and the person who wishes to determine his weight.
The free body diagram of the person on a weighing scale is represented in the attached figure.
As we can see for equilibrium
where,
R is the reaction force between the support and the person
W is the weight of the person which by definition is the force that the earth exerts on the person.
Thus according to the above relation we conclude that that support force of the scale is equal to the gravitational force in magnitude but is opposite in direction.
Answer:
x = 2.26 miles from the shore P i.e. point at which boat be landed.
Explanation:
x is the distance from point of landing i.e R and P
So, she cover a distance miles
She rows with a speed of 3 miles per hour.
So, time taken for rowing
She walks a distance = RQ = 14-x
She walks with a speed of 4 miles per hour.
So, time taken by the woman for walking \
Thus, total time taken
For total time to be least, T ' = 0
T '
x = 2.26 miles from the shore P
