A wave is characterized by the cyclic occurrences of crests and troughs. Wavelengthis defined as the distance between two consecutive troughs or two crests and the Frequency is defined as the number of cycles that pass through a point per second
The speed of the car passing you is 6 m/s while car is moving 6 m/s behind the car.
<h3>Relative velocity of the car</h3>
The speed of the car passing you is determined by applying relative velocity principle as shown below;
Vr = Va - Vb
Vr = 26 m/s - 32 m/s
Vr = -6 m/s
Thus, the speed of the car passing you is 6 m/s while car is moving 6 m/s behind the car.

lol what is this question
The atmosphere creates a cover over the earth preventing us from seeing space and it’s natural color and the light that is created by the sun reflected on the ocean creates the color that the sky appears to be blue
Answer:
The minimum coefficient of friction is 0.22
Explanation:
Suppose If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward the inside of the curve.
We need to calculate the ideal speed to take a 85 m radius curve banked at 15°.
Given that,
Radius = 85 m
Angle = 15°
Speed = 20 km/h
We need to calculate the ideal speed
Using formula of speed
Put the value into the formula
We need to calculate the minimum coefficient of friction
Using formula for coefficient of friction
Put the value into the formula
Hence, The minimum coefficient of friction is 0.22
