Explanation:
First, we will calculate the torque because of the rope wrapped around the drum as follows.
torque1, =
= 3.496 N m
Now, we will calculate the torque because of the rope around the core as follows.
torque2, =
= 3.046 N m
(Since, we are provided with any figure which means that the torque can act either in the same direction or in the opposite direction.)
So, if the torque is acting in the same direction then,
torque = torque1 + torque2
= (3.496 + 3.046) N m
= 6.542 Nm
And, if the torque is acting in the opposite direction then,
torque = torque1 - torque2
= (3.496 - 3.046) Nm
= 0.45 Nm
Answer:
net force= 2000-1000=1000
a=v-u/t=5/20=1/4
m=?
m=f/a
=1000÷1/4=4000kg
Answer:
150N
Explanation:
formula= pressure= force/area
300pa= x/0.5
300*0.5= x
150N= x
force= 150N
Answer:
Centre of mass is the point at which the distribution of mass is equal in all directions, and does not depend on gravitational field. Centre of gravity is the point at which the distribution of weight is equal in all directions, and does depend on gravitational field.

Answer:
B is correct
Explanation:
Battery contains sulfuric acid H2SO4. As the battery cools and eats with the running of the motor, hydrogen gasses is released from electrolytic reactions and escapes through the vents. it mixes with other particulates. The mixtures react at the electrical terminals of the battery and corrosion is formed.
Corrosion can be prevented by the addition of anti corrosion gel. It can also be removed by scrubbing the terminals with a hard brush
