Answer:
966 mph
Explanation:
Using as convention:
- East --> positive x-direction
- North --> Positive y-direction
The x- and y- components of the initial velocity of the jet can be written as
While the components of the velocity of the wind are
So the components of the resultant velocity of the jet are
And the new speed is the magnitude of the resultant velocity:
The wave frequency is 2 Hz.
What is wave frequency ?
The number of waves that pass through a fixed point in a given amount of time is referred to as the wave frequency. The hertz is the SI unit for wave frequency (Hz).
where,
Given,
The waves frequency is 2 Hz.

Answer:
1.85 J/K
Explanation:
The computation of total change in entropy is shown below:-
Change in Entropy = Sum Q ÷ T
=
= -3.12 + 4.97
= 1.85 J/K
Therefore for computing the total change in entropy we simply applied the above formula.
As we can see that there is heat entering the reservoir so it will be negative while cold reservoir will be positive else the process would be impossible.
Answer:
Part a)
%
Part b)
%
Explanation:
As we know that total power used in the room is given as
here we have
Part a)
Since power supply is at 110 Volt so the current obtained from this supply is given as
now resistance of transmission line
now power loss in line is given as
Now percentage loss is given as
%
Part b)
now same power must have been supplied from the supply station at 110 kV, so we have
now power loss in line is given as
Now percentage loss is given as
%
