Answer:
So, if the car slips in mud it will either skid or slide depending on the size of the mud puddle.
Does this work?
The height of the roof is <u>3.57m</u>
Let the drops fall at a rate of 1 drop per t seconds. The first drop takes 5t seconds to reach the ground. The second drop takes 4t seconds to reach the bottom of the 1.00 m window, while the 3rd drop takes 3t s to reach the top of the window.
Calculate the distances traveled by the second and the third drops s₂ and s₃, which start from rest from the roof of the building.
The length of the window s is given by,
The first drop is at the bottom and it takes 5t seconds to reach down.
The height of the roof h is the distance traveled by the first drop and is given by,
the height of the roof is 3.57 m
Answer:
Explanation:
velocity of source, Vs = 114 m/s
original frequency, f = 3.65 kHz
velocity of observer , Vo = 0 m/s
velocity of sound, v = 334 m/s
let the frequency is f'.
The formula for the doppler effect is given by
where, v is the velocity of sound.
f' = 5.54 kHz
Answer: All of the above.

Explanation:
If both stars explode in simultaneously in the <em>your </em>frame of reference then obviously you will see the two flashes simultaneously, and therefore, the time difference between the events would be zero.
If however, the stars exploded simultaneously in their frame of reference, then you would not observe the flashes simultaneously. Then the time difference between the events will not be zero, rather, you will observe star B exploding first and star A after.
