Answer:
In our project, we have a class one lever that is hit by a pulley basket, thus letting a ball roll down.
Explanation:
The comet which is violent and large scale, causing sudden and violent upheaval is known as "Cataclysmic Comet"
Hope this helps!
Average acceleration = (change in speed) / (time for the change)
The missile's change in speed is (5,000 - 0) = 5,000 m/s
Average acceleration = (5,000 m/s) / (10 sec)
= 500 m/s² (about 51 Gs)
Inconveniently, this isn't one of the choices on the list. Is there something wrong, either with the choices or with my solution ?
No. Relax. Everything is OK.
500 meters is the same thing as 0.5 kilometer. So my answer can also be written as 0.5 km/s² . That doesn't change anything, and it IS one of the listed choices.
The average acceleration is <em>0.5 km/sec² (d)</em> .
Explanation:
In a heat exchange, the temperature change is inversely proportional to the specific heat capacity. Since substance A has a heat capacity that is much greater than that of substance B, the temperature change of substance A will be less than the temperature change of substance B. Therefore, the final temperature is closer to that of 
than 
.
Answer:
F = 
.
Explanation:
Gravitational force between two objects of masses 
kept at a distance r is given by the formula
F =
Here ,
= 2m
= 
Thus , F = 
F = .
