Answer:
1.67m
5m/s
Explanation:
Wavelength of the wave = 3m
Speed of the wave = 5m/s
The distance between crest and the adjacent trough of water waves is known as the wavelength of a wave.
To find the frequency ;
V = f∧
V is the speed of the wave
f is the frequency
∧ is the wavelength
Insert the parameters and find the frequency;
f = V/ ∧ = 5 / 3 = 1.67Hz
The rate at which the wave passed a given point is the speed of the wave and it is 5m/s
Rate of change of velocity is called acceleration. When this rate of change is constant, it is called uniform acceleration. Like the change of velocity of an object falling freely under gravity. Its velocity increases by 9.8 m every second. This acceleration is denoted as 9.8m/s^2
Answer:False
Explanation:
Turn the key to lock is not advisable as it lock the steering wheel and may create a dangerous situation.
Following steps can be taken in this situation
- Try to press the brake to stop the vehicle
- Shift gear to neutral in order to cease the acceleration of car.
- Try to lift the gas pedal in order to decrease the velocity of car.
