Answer:
The second universal law, the law of vibration, posits that everything (every atom, object, and living thing) is in constant motion, vibrating at a specific frequency.

It’s true the acceleration of falling objects on earth due to gravity is 98ms2
Answer:
A., B., and C.
Explanation:
An Ohmic material is a material that obeys Ohm's Law, V = IR.
In contrast, a non-Ohmic material is one that does not obey Ohm's law.
Ohm's law states that the voltage across an electrical object is proportional to the current flowing through it, with the constant of proportionality being Resistance, R (in Ohm's).
The only Non-Ohmic material is the semiconductor, as semiconductors do not obey Ohm's law.
Answer:
Centre of mass of any body is a point where all mass of a body is supposed to be concentrated
it lies in geometrical centre....
Answer:
230.26 N
Explanation:
Since the speed is constant, acceleration is zero hence the net force will be given by the product of mass, coefficient of friction and acceleration due to gravity
F=0.72*32.6*9.81=230.26 N
