Answer:
Final velocity will be equal to 14 m/sec
Explanation:
We have given initial velocity u = 5 m/sec
Constant acceleration is given
Time t = 6 sec
We have to find the final velocity
From first equation of motion , here v is final velocity, u is initial velocity , a is acceleration and t is time
So
So equal final velocity will be equal to 14 m/sec
I believe it's b. A flashlight
50 g = 0.5 kg. a = 5 / 0.5 = 10 m/s^2.
Yes,
It is because the speed of sound in solids is very higher than speed of sound in gasses(air). As the molecules present in the solids are very close to each other and transfer disturbance easily and quickly to other molecules. In gasses molecules are farther apart and require more time to travel. Hence speed of sound in gasses are lower than in solids.
Second reason '
AS velocity = V = square root [ elastic modulus /density ]
Gasses are more compressible and hence have smaller elastic modulus so have lower speed .
