<span>The force will be zero if the wagons are moving at a constant speed (i.e. not accelerating), as there is no frictional force to overcome. If the wagons are accelerating, the force will be proportional to the acceleration, and 20% of the force applied by A.</span>
We can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.
<h3>What is torque</h3>
The torque experienced by an object a given position is the product of the applied force and the perpendicular distance of the object.
When 5 kg mass is at 2 m on the left, another 5 kg at 2 m on the right will balance it.
<h3>Position of 10 kg mass on the right</h3>
Apply principle of moment
<h3>Net torque</h3>
<h3>Position of the 20 kg mass</h3>
<h3>Net torque</h3>
Thus, we can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.

Answer:
Freezing Point - Lower
Boiling Point - Higher
Solid- liquid transition line in the phase diagram has a negative slope, but the liquid-gas transition line has a positive slope. Since there is more air pressure at 100m it will take less to freeze the water but more to boil it since it requires a larger temperature under larger pressures
Answer
given,
wavelength = λ = 18.7 cm
= 0.187 m
amplitude , A = 2.34 cm
v = 0.38 m/s
A) angular frequency = ?
angular frequency ,
ω = 2π f
ω = 2π x 2.03
ω = 12.75 rad/s
B) the wave number ,
C)
as the wave is propagating in -x direction, the sign is positive between x and t
y ( x ,t) = A sin(k x - ω t)
y ( x ,t) = 2.34 x sin(33.59 x - 12.75 t)
Answer:
emf will also be 10 times less as compared to when it has fallen
Explanation:
We know, from faraday's law-
and
So, as the height increases the velocity with which it will cross the ring will also increase.
Given
Now, from
From equation a and b we see that velocity when dropped from is 10 times greater when height is 40 so, emf will also be 10 times less as compared to when it has fallen
