Answer:
Heat is similar to and different from internal energy
Explanation:
Similarity:
First thing to remember is that heat and internal energy are both different forms of energy. Secondly, heat is directly proportional to internal energy. When you provide heat to the system, its internal energy will increase. So, heat is the part of internal energy.
Difference:
Internal energy is the summation of kinetic and potential energy of a system, means it depends upon movement of particles as well as the particular position of the system while heat is the transfer of the energy due to difference of degree of hotness and coldness of body or a system.
Answer:
Amplitude, A = 0.049 meters
Explanation:
Given that,
A harmonic wave travels in the positive x direction at 6 m/s along a taught string. A fixed point on the string oscillates as a function of time according to the equation :
.......(1)
The general equation of a wave is given by :
.......(2)
A is amplitude of wave
On comparing equation (1) and (2) we get :
A = 0.049 meters
So, the amplitude of the wave is 0.049 meters.

Answer:
50000 μT
Explanation:
From the given information:
the diameter of the loop = 1.0 mm = 0.001 m
no of turns (N) = 200
current (I) = 0.199 A
radius = d/2 = 0.001/2
= 5 × 10⁻⁴ m
Recall that;
the magnetic field at the centre of circular wire is:
= 0.05 T
= 50000 μT
Since the centre of the earth's magnetic field is given to be equal to the magnetic field produced by the wire, then:
the earth's magnetic field = 50000 μT
The Pyrometer. It is used for measuring relatively high temperatures.
