More water evaporates than falls as rain
did u know 3 million tonnes of water gets evaporated from oceans per day
Answer:
8.4 m/s
Explanation:
The toy completes 10 circle in 30 seconds. So its frequency of revolution is

The periof of revolution is the reciprocal of the frequency, so

The radius of the circular path is
r = 4.0 m
So the total distance covered by the toy in one circle is the length of the circumference:

And so the average speed is

Answer:
The star must be moving "closer" to the earth because the wave fronts that are being emitted are shifted toward the blue end of the spectrum (they are closer together)
<u>Answer:</u>
The given statement is a True statement
<u>Explanation:</u>
All cars and trucks have load capacities marked on the jamb of the driver's door, as well as the owner's manual.
This is very significant for braking distance.
A heavier object will require much more braking force and distance to stop, due to New ton's law of motion. “ An object in motion will tend to stay in motion “ .A heavy object will remain in motion longer and require much more force to stop. Four wheel disc brakes are great compared to front disc and rear drum configuration, in dissipating heat, and stopping more efficiently.
Answer:
The average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8.0 s is 24
.
Explanation:
Velocity is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it. Then, the average velocity relates the change in position to the time taken to effect that change.

Velocity considers the direction in which an object moves, so it is considered a vector magnitude.
In this case, the displacement is 192 m and the time period is 8 s. Replacing:

Solving:
velocity= 24 
<em><u>The average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8.0 s is 24 </u></em>
