The latent heat of fusion refers to the solid to liquid or liquid to solid states.
Answer: Option C
<u>Explanation:
</u>
It is known that the inter conversion process from the states of solid to liquid is referred as fusion. So, for these conversions, the external energy in the heat form should be supplied to solid.
This external energy should be greater than the latent heat of solid in order to successfully break the bonds to form liquid. So the change in the enthalpy of the reaction while conversion from solids to liquids are termed as latent heats of fusion.
Even the inter-conversion from liquid to solid state will undergo change in enthalpy where the heat will be released and that is termed as latent heats of solidification. It is found that latent heat of solidification is equal in magnitude but opposite in direction with the latent heats of fusion.
The formula is
V = final velocity = initial velocity U + ( acceleration a * time duration t )
V = U + a t
= 4.5 m/s + 2.5 m/sec² * 7 sec = 4.5 + 17.5 = 22 m /sec
Acceleration means, every second the velocity or speed increases by that amount. Here it is 2.5. After one second velocity become 2.5 m/s more. after 2 seconds it is 5 m/s more. after 3 seconds, speed is 7.5 m/s more than at start. Like this after 7 seconds, the speed is 7 * 2.5 higher than at the beginning. so computer the total.
If their average velocity is 55 mph Northwest, they won't arrive in Santa Fe.
First of all, the straight-line distance from Houston to Santa Fe is only 740 miles. And if the headed out from Houston going northwest and maintained that heading, then they passed about 135 miles north of Santa Fe.
Let's just work with SPEED, OK ?
If they drove 881 miles at an average speed of 55 mi/hr, then
the trip took them
(881 mi) x (hr / 55 mi) = 16.018 hours (16 hrs 1 min)
Answer:
If we are looking for evidence of something that exists outside of our visible Universe and leaves no trace within it, it seems that the idea of a Multiverse is fundamentally untestable. But there are all sorts of things that we cannot observe that we know must be true. Decades before we directly detected gravitational waves, we knew that they must exist, because we observed their effects.

Answer:
density = 0.0933 kg/m
speed = 27.581 m/s
Explanation:
given data
length L = 4.5 m
mass m = 0.42 kg
force F = 71 N
to find out
mass density and speed
solution
we find linear mass density
linear mass density = mass / length
put here all value
density = 0.42 / 4.5
density = 0.0933 kg/m
and
speed of wave
speed = √(F/density)
speed = √(0.42/0.933)
speed = 27.581 m/s
