Answer:
Power emitted will be 0.314 mW
So option (A) will be correct option
Explanation:
We have given threshold hearing 
Distance is given r = 5 km =5000 m
We have to find the power emitted
Power emitted is equal to
=
So power emitted will be 0.314 mW
So option (A) will be correct option.
<span>The two factors which determine the period of a pendulum is:
A) Length of the string
B) Acceleration of gravity
In short, Your Answer would be Option C
Hope this helps!</span>
Wouldn't mass stay the same and acceleration increase or am I mistaken?
When the leveling bulb is higher than the water level, the pressure in the system is greater than atmospheric pressure. This statement is true.
In the physical sciences, pressure is defined as the stress at a point within a confined fluid or the perpendicular force per unit area. A 42-pound box with a bottom area of 84 square inches will impose pressure on a surface equal to the force divided by the area it is applied to, or half a pound per square inch.
Atmospheric pressure, which is roughly 15 pounds per square inch at sea level, is the weight of the atmosphere pressing down on each unit area of the Earth's surface. Pascals are used to express pressure in SI units; one pascal is equivalent to one newton per square meter. Almost 100,000 pascals of atmospheric pressure are present.

Answer:
B) 1:100
Explanation:
this explanation is actually simple.
you can see this problem as a simple comparation if you move for example
1:10
if you move 1 cm you are going to move 10cm in the other side usually is used for planes in architecture or sizing issues, so, if the scale need to be grater, that is if is necessary to increase the number inthe right side in this case 10 cm to 100cm it is because in 100 the resolution is better.
you can see this problem as a fraction
1/10 or 1/1000
