a)
Amplitude of wave is given as maximum displacement from mean position
So here amplitude is 1.25 cm
b)
Wavelength is the length of the wave that it travels in one time period
From graph we can say the wavelength is given as 3cm
PART C)
Time period of wave is the time after which it repeats its shape
Speed of the wave = 21 cm/s
time period = wavelength / speed
Now frequency is
PART D)
Time period = \frac{1}{f}[/tex]
Answer:
6692J
Explanation:
Power is defined as the rate at which work is being done.
So,
Power =
Work done = Power x time
Given parameters:
Power = 478watts
Time = 14s
So;
Work done = 478 x 14 = 6692J
Acceleration of car is 4m/s²
Acceleration of truck is 2m/s²
Explanation:
Given parameters:
Force on the car and truck = 12000N
Mass of car = 3000kg
Mass of truck = 6000kg
Unknown:
Acceleration of car = ?
Acceleration of truck = ?
Solution:
Force is product of mass and acceleration. It is a push or a pull exerted on a body.
Force = mass x acceleration
Make acceleration the subject of the formula;
Acceleration =
Acceleration of car = = 4m/s²
Acceleration of truck = = 2m/s²
