Answer:
Explanation:
Half life = 5.6
no of half life in 15.78 years = 15.78 / 5.26
= 3 .
N₀ is original mass , N is mass after n number of half lives.
Inserting the given data in the equation above
N₀ = 50 x 2³
= 400 gm .
original sample will contain 400 gms of sample.

Divide 10 by 3. ...
Average 3.33 and 3. ( ...
Repeat step 2: 10/3.1667 = 3.1579.
Answer: The volume of the gas increases as the temperature increases. As temperature increases, the molecules of the gas have more kinetic energy. therefore it increases! Hope this helps you!
Explanation:
200 ms² is the kinetic energy for an object that weighs 40g and moving at 10 m/s.
<h3>What are kinetic energy ?</h3>
Kinetic energy is the power that an object has had as a result of motion. To accelerate an object, a power must be supplied to it. To apply a force, we must exert effort. The power is transported to the object when work is accomplished, which causes it to move at a new, constant pace.
<h3>What makes kinetic energy so important?</h3>
The capacity to perform work is unquestionably the most important characteristic of kinetic energy. Force acting on to an object while it is traveling is referred to as work. Energy and work are interchangeable because of their close relationship.
<h3>Briefing:</h3>
Using Kinetic Energy Formula:
K.E = 1/2 mv²
K.E. = 1/2 * 40 * 10
K.E. = 200 ms²
