Answer:
"When face is placed between the concave mirror and its focus, it produces a magnified image. This enlarged image of face is helpful in makeup as even pores of skin are clearly visible."
Answer:
The requested distance is 4320 meters
Explanation:
We can use the formula for velocity in this movement at constant velocity (v), which is defined as the quotient between the distance covered divided the time it took:
Since we know the velocity and the time, we can solve for the distance:

of the ball changes.
(Unless, of course, it gets so hot that it melts,
and part of it falls off
and rolls under the table.)</span>
The correct order of events for the electromagnetic generators generate electricity is
b) The conducting coil rotates
c) The number of magnetic field lines passing through the coil changes
d) The flow of cuurent through the circuit
a)The stationary electrons in the wire experience a force.
The electromagnetic generators is working on the principle of electromagnetic induction. It has been used in many places as standby power sources in shops, homes etc.
It works by converting the mechanical energy into electrical energy by making use of electromagnetic conduction. which means the creation of current my moving the wire which is next to the magnet.

Answer:
346819 Pa or ,347000 Pa in 3 significant figures
Explanation:
P1= 325000Pa , T1= 283K ,
P2=? T1= 302 K
as here volume and mass both are constant so using ratio method for pressure temperature law we have P1/T1 = P2/T2
THIS WE CAN ALSO OBTAIN BY RATIO METHOD FOR GENERAL GAS LAW AS
P1V1/(m1T1 ) = P2 V2/ (m2 T2)
IF V1 = V2 =V AND m1=m2=m then expression reduces to
P1/T1 = P2/T2
or P2 = (P1/T1)×T2
P2 = (325000/283) × 302
P2 = 1148.41×302
P2=346819
P2 = 347000 Pa in 3 significant figures
