The type of mass movement that happens very slowly is Creep.
Explanation:
Mass movement, usually known as mass wasting, is that the descent movement of a mass of surface materials, like soil, rock or mud. This mass movement generally happens on hillsides and mountains because of the influence of gravity and may happen terribly slowly or terribly quickly.
As we know that speed of sounds is given as
here we know that
t = 23 degree C
now from above equation we will have
now we also know that distance between two consecutive resonance length is half of the wavelength
now we know that
so frequency will be 786 Hz
Answer: Speeding Up
Explanation:
Force is proportional to the acceleration of an object. The greater the force, the more acceleration will be produced.
When the force on the tire is equal to the weight of the car, the car is reaching a stability as a result of increase in motion.
But when the force of the load on the tire is quite large(most likely several times the weight of the car) and is directed forward, then, the car is at high speed.
Answer:
185 N
Explanation:
Sum of forces in the x direction:
Fₓ = -(80 N cos 75°) + (120 N cos 60°)
Fₓ = 39.3 N
Sum of forces in the y direction:
Fᵧ = (80 N sin 75°) + (120 N sin 60°)
Fᵧ = 181.2 N
The magnitude of the net force is:
F = √(Fₓ² + Fᵧ²)
F = √((39.3 N)² + (181.2 N)²)
F = 185 N
