Answer:
500,000 hertz
Explanation:
Wavelength= 600 meters
Velocity(b) = 3 × 10^8
Frequency=?
Therefore the frequency can be calculated as follows
Velocity= frequency × wavelength
Frequency= 3 × 10^8/600
= 500,000 hertz
Hence the frequency is 500,000 hertz
Given that,
Angle = 30°
Initial velocity = 15 m/s
We need to calculate the time of flight
Using formula of time of flight
Where, u = initial velocity
g = acceleration due to gravity
Put the value into the formula
We need to calculate the final velocity of the ball
Using equation of motion
Hence, The final velocity of the ball is 29.7 m/s.
1) the object would change color (start to rust or just chnage color)
2) The new substance is ireversable (cant chnage back to original form)
3)theres gas formations (its can change into a gas property)
There is no factor on your list of choices that has any effect.
