Answer:
a)1.13×10³
b)1.6×10³
Explanation:
Given:
Boltzmann's constant (K)=1.38×10^-23 J/K
atmoic mass of helium = 4 AMU or 4×1.66×10^-27kg
a)The formula for RMS speed (Vrms) is given as
where
K= Boltzmann's constant
T= temperature
m=mass of the gas
b) RMS speed of helium when the temperature is doubled
Answer:
In the same direction as the force
Explanation:
Consider an object in which force is applied. The force applied moves the object in the direction of the force.
Suppose if the force is applied to the moving object in that case object moves in the direction of the stronger force.
Thus, according to the given question the applied force moves the object in its direction.
