Answer:
The speed of the raindrop is 11.55 m/s.
Explanation:
We need to find the speed of the rain in the "y" direction. We have:
: speed of the raindrop at 60° (vertical) =?
: speed of the car = 20 m/s (in the "x" direction)
Hence, the speed of the car and the speed of the raindrop are related by:
Therefore, the speed of the raindrop is 11.55 m/s.
I hope it helps you!

Answer:
speed = distance/time so v = 100/50 m/sec = 2 m/sec.
D = 2T ⇐formula for distance, in meters, for trip duration in T seconds, ASSUMING CONSTANT SPEED.
7.5 × 10¹⁴ Hz is the highest frequency of visible light when wavelengths of visible light range from 400 nm to 700 nm.
The distance a wave travels in one unit of time is known as the wave speed (v).Taking into account that the wave travels one wavelength in one interval,
v=λ/T
Given that T = 1/f, we can write the equation above as,
V = f λ
Given data:
Minimum wavelength of visible light = 400 nm = 4 × 10⁻⁷ m
Speed of light = 3 × 10⁸ m/s
Frequency = c/λ = 3 × 10⁸ / 4 × 10⁻⁷
= 7.5 × 10¹⁴ Hz

The solution to your problem is as follows:
<span>5km/h2 x 1 h/60 min x 1 min/60 sec x 1000m/km = 1.39 meters per second change each second.
</span>
Therefore, the speed change each second is <span>1.39 meters per second change each second.
