Answer:
The water molecule cannot escape, since the average velocity of the water molecules is less than one sixth of the escape velocity of venus.
Explanation:
The average speed of gas molecules is given by:
R is the gas constant, T is the temperature and M the molar mass of the gas.
We know that a water molecule has a mass that is 18 times that of a hydrogen atom:
So, we have:
The water molecule cannot escape, since the average velocity of the water molecules is less than one sixth of the escape velocity of venus:
Explanation:
It is given that,
Magnitude of charge,
It moves in northeast direction with a speed of 5 m/s, 25 degrees East of a magnetic field.
Magnetic field,
Velocity,
We need to find the magnitude of force on the charge. Magnetic force is given by :
<em>Since</em>,
So, the force acting on the charge is and is moving in positive z axis. Hence, this is the required solution.
