The gravitational potential energy
gpe = mgh

The approximate speed of sound in dry (0% humidity) air, in meters per second, at temperatures near 0 °C, can be calculated from

Here
Temperature in Celsius
Replacing with our values we have that



Therefore the speed of sound in air at that temperature is 366.1m/s
It is -59 i think or just ask someone esle for help
Answer:
2.2 x 10-19
Explanation:
Kinetic Energy = 1/2 m v ^2
Answer:
10 km/hr/s
Explanation:
The acceleration of an object is given by

where
v is the final velocity
u is the initial velocity
t is the time
For the car in this problem:
u = 0

t = 6 s
Substituting in the equation,
