Answer: 4,32 10^10 m
Explanation: The relationshiop between the light speed, distance and time is given by:
speed of light = distance/time
distance= speed of ligth * time
distance= 3*10^8 m/s * 2.4*60 s= 4,32*10^10 m
Answer:
Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.
Answer:
1.30 m
Explanation:
The pressure (P) exerted by a column of a liquid can be calculated with the following expression:

where,
ρ is the density of the liquid
g is the gravity
h is the height of the column
If both liquids exert the same pressure:

In a non accelerated frame, also called inertial frame, when no additional forces are acting upon the body.
For instance, a scale in free fall will not record the weight, but zero, like the astronauts. But also, if someone is pulling the object or pushing it, the scale will record some other value.
