Answer:
A
Explanation:
because newton's second law states that if a resultant force acts on an object then, it will accelerate in the direction of the resultant force
Explanation:
It is given that,
The period of the carrier wave, T = 0.01 s
Let f and 
are frequency and the wavelength of the wave respectively. The relationship between the time period and the frequency is given by :
f = 100 Hz
The wavelength of a wave is given by :
So, the frequency and wavelength of the carrier wave are 100 Hz and 
respectively. Hence, the correct option is (c).
A: Some physical properties change, but the substance keeps its identity.
Carbon isn’t because all the others on the list are naturally made apart from carbon which is man made because of all the pollution . X
