Use the inverse square law, thus if you move a distance of 3m away, the sound intensity decrease by 1/3^2= 1/9
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> .
If solid, cold metal like brass doesn't melt at room temperature like ice does, than the bass can stand much more heat then a ice cube, so it needs to be hotter to melt, so the melting point of ice is lower then brass's melting point
This relationship is called commensalism.
so as this ant moves
5 cm every second you multiply 5 by 120 (60 per minute as there are 60 seconds in a minute)
this is 600 cm
or
6 meters
