Answer:

This question is incomplete but the completed question is below

A ray of light parallel to the principal axis of a spherical mirror passes through its _____ after reflection.

(a) focus (b) pole (c) centre of curvature (d) imaginary centre of curvature

The correct option is (a)

Explanation:

After reflection, a ray of light will usually appear to diverge after they hit a spherical mirror, extending behind the mirror to meet at a point (called the focus or focal point) between the pole and the centre of curvature of this mirror. Hence, option a is the correct option.

Gas stored in a tank at 273 k has a pressure of 388kpa. The safe limit for the pressure is 825kpa at whst temperature Will gas r

vagabundo [1.1K]

Answer:

The answer to your question is T2 = 580.5 °K

Explanation:

Data

Temperature 1 = T1 = 273°K

Pressure 1 = P1 = 388 kPa

Pressure 2 = P2 = 825 kPa

Temperature 2 = ?

Process

1.- Use the Gay-Lussac law

P1/T1 = P2/T2

-Solve for T2

T2 = P2T1/P1

-Substitution

T2 = (825)(273) / 388

-Simplification

T2 = 225225 / 388

-Result

T2 = 580.5 °K

An important news announcement is transmitted by radio waves to people sitting next to their radios 42 km from the station and b

Alik [6]

Answer:

news will reach to the listener who are 42 km apart

Explanation:

given,

distance of the radios from the station = 42 Km

speed of the sound in the air = 343 m/s

distance of the people = 9.26 m

$time =\dfrac{distance}{speed}$

time taken by the signal to reach to the radio

speed of the electromagnetic wave to reach to the people

speed of electromagnetic wave = 3 × 10⁸ m/s

$t =\dfrac{42000}{3 \times 10^8}$

t = 1.4 μs

time taken to reach to the people

$time =\dfrac{distance}{speed}$

$t =\dfrac{9.26}{343}$

t = 27 ms

time taken by the station to radio is less.

hence, news will reach to the listener who are 42 km apart
