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
%
Answer:20/47 meter per second
Explanation:
Mass of arrow(ma)=0.25kg
Velocity of arrow(va)=12m/s
Mass of target(mt)=6.8kg
Velocity of target(vt)=0 since target is at rest
Conservation of linear momentum says that :
maxva+mtxvt=(ma+mt)V
V=(maxva+mtxvt)/(ma+mt)
V=(0.25x12+6.8x0)/(0.25+6.8)
V=3/(7.05)
V=20/47 meter per second

Answer:
The particle's position is
The particle's velocity is
Explanation:
From the question we are told that
at
and from the graph at t = 0
Now the acceleration which is the slope of the graph is mathematically represented as
The negative sign shows that it is a negative slope
Now to obtain the velocity at t = 2 sec
We use the equation of motion as follows
substituting values '
Now to obtain the position of the particle at v = 2 m/s
We use the equation of motion as follows
So
From above at
So the position at t = 2 s
Answer:
Explanation:
Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.
(At constant volume and number of moles)
where,
= initial pressure of gas =
= final pressure of gas = ?
= initial temperature of gas =
= final temperature of gas =
Therefore, the final gauge pressure in the car tires is
