Answer:
it takes 3 hours to travel
Explanation:
120 ÷ 40 = 3
Answer:
low pressure systems
Explanation:
with a low pressure system over the area the storm can't form
Given: Mass m= 10 g convert to Kg m = 0.01 Kg Velocity V = 300 m/s
Required: Kinetic energy = K.E = 1/2 mV²
K.E = 1/2 (0.01 Kg)(300 m/s)²
K.E = 450 J
Sound is all about vibrations.
The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. This results in a wave of vibrations travelling through the air to the eardrum, which in turn also vibrates.
