Gravity is the CAUSE of 'falling', and the cause of acceleration
while falling.
Objects falling near the Earth's surface all have the same acceleration ...
about 9.8 m/s².
You're hearing a higher frequency than the sound that's actually coming from the siren on the ambulance, so it must be moving TOWARD you.
Answer:
Gamma radiation .
Explanation:
Three types of emission result at the time of nuclear emission .
alpha emission
Beta emission
Gamma radiation emission
Gamma radiation results in the emission of gamma ray . This is a very high frequency radiation . It is not a particle having charge and mass like alpha and beta emission . So it has no effect on the mass and charge of the product that is formed after gamma radiation . The only effect it has on the product is that it reduces the kinetic energy of the emitting particles or it reduces the internal energy of the product . It causes negligible change in the mass of the product and no change in the charge of the product.
That is why , generally this product is not written in the nuclear reaction .
