A skater glides along a circular path of radius 3.00 m. If he coasts around one half of the circle, find the magnitude of the di
1 answer:
Answer:
The magnitude of the displacement is 6.00 m.
Explanation:
Given that,
Radius = 3.00 m
Displacement :
The displacement is the shortest distance between initial and final points,
We need to calculate the magnitude of the displacement
Using formula of displacement
Put the value into the formula
Hence, The magnitude of the displacement is 6.00 m.

Answer:
a) The final pressure is 1.68 atm.
b) The work done by the gas is 305.3 J.
Explanation:
a) The final pressure of an isothermal expansion is given by:
Where:
: is the initial pressure = 5.79 atm
: is the final pressure =?
: is the initial volume = 420 cm³
: is the final volume = 1450 cm³
n: is the number of moles of the gas
R: is the gas constant
Hence, the final pressure is 1.68 atm.
b) The work done by the isothermal expansion is:
Therefore, the work done by the gas is 305.3 J.

When silver is poured into the mould the it will solidify
In this process the phase of the Silver block will change from liquid to solid.
This phase change will lead to release in heat and this heat is known as latent heat of fusion.
The formula to find the latent heat of fusion is given as
here given that
now we can find the heat released
So it will release total heat of 55.5 kJ when it will solidify
