A Dodge Stealth is driving at 70 mph on a highway. It passes a BMW going the same direction. The BMW is moving 7 mph backward relative the Dodge. 63 mph is the velocity of the BMW
Answer: Option A
<u>Explanation:</u>
Given is the speed of the dodge stealth as 70 mph passing by the BMW moving with 7 mph relative to Dodge. Thereby, to calculate the velocity of BMW, relative velocity concept has to be employed.
As we know that the relative velocity tells us about relative velocity of mobile reference system as the difference or sum of the initial reference system.
Therefore,
velocity of the BMW = 
Velocity of the dodge = 
Velocity of the BMW with respect to dodge = 
As per the formula,
in the same direction as the wave
Explanation:
In a compression wave, the particles in the medium moves in the same direction as the wave source.
A wave is generally defined as a disturbance that transmits energy.
- There are two types of waves based on the direction through which they are propagated.
- Transverse waves are directed perpendicularly in the direction of propagation.
- Examples are electromagnetic waves.
- Longitudinal waves are parallel to their source. Examples are sound waves, p-waves.
- They are made up of series of rarefaction and compression.
