Answer:
D
Explanation:
According to newton's 2nd law rate of change of momentum is directly proportional to the force applied on the body. Since, net Force is zero this means momentum did not change or momentum of the body remained constant.
Hence, the system have constant value of momentum. Therefore, option D is correct.
Answer:
Explanation:
A unit used to measure a vector quantity is the
c) Newton
A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be in direct proportion. ... The equation shows that, as absolute temperature increases, the volume of the gas also increases in proportion.

Answer:
Resistance, 
Given:
V = 407.1 V
Current through the resistor, I = 0.850 mA = 
Time constant for the circuit, 
Solution:
Initially the capacitor is uncharged, the current in the circuit remains same.
Thus
At t = 0
the current in the circuit, I = 
Therefore,
Resistance, R = 
R = 
Now, for calculation of Capacitance, C:
Time constant for the circuit,
