Answer: A force must cause an object to move along the same direction as the force.
Explanation:
Work is defined as displacement in the position of an object due to action of force. Mathematically the work done is a product of force and displacement of an object. The direction of the force applied and direction in which object is displaced is always same.
When work is done,a force must cause an object to move along the same direction as the force.
Answer : The correct option is,
Explanation :
To calculate the pressure of gas we are using ideal gas equation as:
where,
P = pressure of gas = ?
V = volume of gas = 0.046 L
n = number of moles of gas = 3.4
R = gas constant = 8.314 L.kPa/mol.K
T = temperature of gas = 298 K
Now put all the given values in the above formula, we get:
Therefore, the pressure of gas is,
