An ideal gas occupies a volume V at an absolute temperature T. If the volume is halved and the pressure kept constant, what will
Kruka [31]

Answer:

It will be halve of T

Explanation:

V1 = V

T1 = T

V2 = ½V

T2 = x

What is the kinetic energy of a 5 kg object moving at 7 m/s?
valina [46]

Answer:

122.5 Joule, or 122.5 j

Explanation:

Given,

mass of the object (m) = 5 kg

velocity of the object (v) = 7 m/s

Kinetic energy = \frac{1}{2} × m × v²

Applying the formula:

Kinetic energy = \frac{1}{2} × 5 × 7²

⇒ \frac{1}{2} × 5 × 7 × 7

⇒ \frac{245}{2}

⇒ 122.5 Joule, or 122.5 j

Kinetic energy is the energy that an object gains as the result of the motion.  It also depends on the mass of the object and force with which the motion is applied.  In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.
