ANSWER: A ramp meter, usually is a basic traffic light or a two-section signal light, together with a signal controller, that regulates the flow of traffic that enters freeways according to the most traffic conditions.
Answer:
The cheetahs velocity component due north is 6.99 m/s
The cheetahs velocity component due west is 18.21 m/s
Explanation:
Given;
speed of the cheetah, v = 19.5 m/s
direction of the cheetah's speed, θ = 69°
Find the attached document for explanation
temperature decreases at higher altitudes because as air rises the pressure decreases.
An earthquake is a mechanical wave
Here in this case we can use energy conservation law to find out the speed
As per energy conservation we know that
initial kinetic energy + initial potential energy = final kinetic energy + final potential energy
so the speed of the pendulum bob is approx 2 m/s when it is 0.8 m above the floor
