Answer:
Wl = 1740 N
Explanation:
maximum lift weight unaided = force exerted (F) = 650 N
length of the wheelbarrow (L) = 1.4 m
weight of the wheelbarrow (w) = 80 N
distance of center of gravity of the wheel barrow from the wheel = 0.5 m
distance of center of gravity of the load from the wheel = 0.5 m
find the weight of the load (Wl)
from the diagram attached we can see that there is going to be a rotation about the axis A. let clockwise rotation be positive
ΣT = (F x 1.4) - ((Wl x 0.5) + (w x 0.5) = 0
(F x 1.4) = ((Wl x 0.5) + (w x 0.5)
Wl =
Wl =
Wl = 1740 N
I am pretty sure that when discussing the Earth's magnetic field we could say that the Earth has a random collection of magnetic poles dispersed in different locations. This statement is the only correct one which represents the main points of <span>magnetic field's characteristics and features. Hope it will help you!</span>
Answer:C
Explanation:
Given
Both ball are thrown simultaneously with same velocity
Suppose h be the height of roof and u be the initial velocity of balls
For ball thrown from room initial total energy is
Now this ball potential energy convert to kinetic energy and add up in available kinetic energy to give 100 J at bottom
For second ball, energy at bottom is equal to kinetic Energy of ball
Therefore this energy remains constant and only converts to Potential Energy as ball moves upward
but as soon as ball hit the ground energy will be less than 100 J because first ball has sum of Potential and Kinetic energy .
Answer:
Explanation:
Here by energy equivalence we can say that energy given by the metal piece is same as the energy absorbed by the water
so here we have
here we know that
