From ideal gas law, PV=nRT
where P is the pressure, V is the volume of the container, n is number of moles, R is the gas constant and T is the temperature.
Hence,
T= 110.65 k
Kinetic Energy =
K.E=
The energy an object has as a result of motion is known as kinetic energy.
A force must be applied to an object in order to accelerate it. We must put in effort in order to apply a force. After the work is finished, energy is transferred to the item, which then moves at a new, constant speed. Kinetic energy is the type of energy that is transferred and is dependent on the mass and speed attained.
Kinetic energy can be converted into other types of energy and transported between objects. A flying squirrel may run into a chipmunk that is standing still, for instance. Some of the squirrel's initial kinetic energy may have been transferred to the chipmunk or changed into another kind of energy after the collision.

Answer:
2.5m/s²
Explanation:
Given parameters:
Mass of car = 2000kg
Force produced by the car = 5000N
Unknown:
Acceleration of the car = ?
Solution:
According to Newton's second law of motion, Force is a product of mass and acceleration.
Force = mass x acceleration
Now, insert the parameters and find the unknown;
5000 = 2000 x acceleration
Acceleration = = 2.5m/s²
Answer:
The frictional force 6.446 N
The acceleration of the block a = 6.04
Explanation:
Mass of the block = 3.9 kg
°
= 0.22
(a). The frictional force is given by
3.9 × 9.81 ×
29.3 N
Therefore the frictional force
0.22 × 29.3
6.446 N
(b). Block acceleration is given by
F = 30 N
= 6.446 N
= 30 - 6.446
= 23.554 N
The net force acting on the block is given by
23.554 = 3.9 × a
a = 6.04
This is the acceleration of the block.
