We first calculate the acceleration on the ball using:
2as = v² - u²; u = 0 because ball is initially at rest
a = (36)²/(2 x 0.35)
a = 1850 m/s²
F = ma
F = 0.058 x 1850
= 107.3 Newtons
Correct answer choice is :
A) As speed changes, wavelength changes and frequency remains constant.
Explanation:
The higher the energy, the higher the frequency and the smaller the wavelength. The relation among wavelength and frequency the greater the frequency, the smaller the wavelength it reflects that short wavelengths are more dynamic than large wavelengths. The wavelength and frequency of light are almost associated. The greater the frequency, the smaller the wavelength. Because all small waves move into space at the very speed, the amount of wave peaks spending by a read point in one second depends on the wavelength.
Answer:
3683.67 m
Explanation:
Formula for maximum height of projectile is given by the equation;
h = u²/2g
Where u is initial velocity and g is acceleration due to gravity
We are given u = 190 m/s
Thus;
h = 190²/9.8
h = 36100/9.8
h = 3683.67 m
Newton's 2nd law of motion . . . . . Force = (mass) x (acceleration)
Divide each side by (mass), and you have
Acceleration = (force) / (mass)
We know the force and mass for this truck, so we can fillum in:
Acceleration = (500 N) / (3,000 kg) = 0.167 m/s² .
