Sound is what i would think
When a ball is thrown up by doing work, the velocity of the ball will be 2.6 m/s.
<h3>What is Work energy theorem?</h3>
It states that the Work done in moving a body is equal to the change in kinetic energy of the body
Kinetic energy = 1/2 mv²
Given is a ball of mass m = 0.750 kg and the work done on ball W = 2.50 J
The ball is initially at rest. So, initial velocity is zero. Then, change in kinetic energy will be
W= ΔK.E = K.Ef - K.Ei
According to work energy theorem, work done is
W = 2.5J = 1/2 x 0.750 x (v)² -0
v =2.6 m/s
Thus, the velocity of the ball is 2.6 m/s

Answer: Malleability
Explanation:
Gold in addition to being so rare, is the most malleable element there is. A Malleable element can be shaped and reshaped without it breaking and gold is so malleable that you can hit it till it becomes so flat, its transparent.
This malleability allowed for the ancient peoples to be able to shape and stamp gold into coins and their rarity made them quite valuable. Even today, investors still shape gold into exquisite designs of coins so it not only has monetary value, but aesthetic value as well.
Answer:
The value is
Explanation:
From the question we are told that
The atmospheric temperature is
The molar mass of carbon dioxide is
The pressure is
The number of moles is
Generally the translational kinetic energy is mathematically represented as
Here R is the gas constant with value
Generally the degree of freedom of carbon dioxide in terms of translational motion is f = 3
So
=>
