<h2>The ice melted is nearly 2.8 kg </h2>
Explanation:
The quantity of heat required to melt the ice can be found by the relation .
ΔQ = m x L
here L is used for the latent heat of fusion .
Its value is 334 J per gram for ice .
Thus m =
=
= 2836 gram
or = 2.8 kg approx
Answer:
Explanation:
the block will move to the right side with small velocity because the force from the left side greater than force from right side. Velocity will be less because of friction and gravitational attraction.
Answer:
Percentage increase in the fundamental frequency is
d)-14.02%
Explanation:
As we know that fundamental frequency of the wave in string is given as

now it is given that tension is increased by 30%
so here we will have


now new value of fundamental frequency is given as

now we have

so here percentage change in the fundamental frequency is given as

% change = 14.02%
