Explanation:
The difference in frequency can be calculated using the formula
f= source frequency from the ship
v'= speed of the wave reflected from the whale = 4.95 m/s
v= speed of the ship.
since, the source frequency and speed of the ship data is missing, calculation of difference in frequency not possible.
Answer:
D. Glacial striations
Explanation:
Glacial striations are marks and grooves carved on a rock surface as the materials carried by it abraded the surfaces of the earth.
True, Large bodies of water change temperature slower than land masses. Land masses near large bodies of water, especially oceans, change temperature as the oceans change temperature: slower and with less extreme fluctuations than land masses farther away.
Answer:
-330 N.
Explanation:
Force is defined as the mass and the acceleration of a body.
The formula of force is given as,
F = m(v-u)/t .................. Equation 1.
Where m = mass of the football, u = initial velocity of the football, v = final velocity of the football, t = time.
Given: m = 0.9 kg, u = 22.0 m/s, v = 0 m/s ( brought it to rest), t = 0.06 seconds.
Substitute into equation 1,
F = 0.9(0-22)/0.06
F = 0.9(-22/0.06)
F = -330 N.
F = -330 N.
Note: The force is negative because it acts against the the receiver.
Jupiter is the first one I think
