Usually the beta particles are electrons with negative charge. And positrons are with positive charge. So they have the same mass and different charges. The answer is (3).
False, because generally forensics collect the evidence to make sure the evidence doesn’t get damaged or tainted.... hope this helps
Molarity= (number of moles of that substance) / (Volume of solution in litres)
7= (number of moles of HCl) / 0.05
Thus,
Number of moles of HCl = 7 x 0.05 = 0.35
The number of moles of HCl will remain unchanged.
Now, for new solution,
0.35= 0.35 / (New volume of solution in litres)
Thus,
New volume = 1 litre
Thus, amount of water added = 1- 0.05 litre = 5.0 M
Answer:
(a) Utilization
Explanation:
Thermodynamic energy are:
<h2>
(1) Kinetic energy:</h2>
Kinetic energy is that type of energy of a body which occurs due to the motion of body. Kinetic energy is always positive. In a bound system, the system remains bound as long as the kinetic energy is less than the potential energy due to the interaction of the body.

<h2>
(2) Potential energy:</h2>
Potential energy is defined as the energy in which the energy is possessed by a body or a system for doing some work, by virtue of its position above the ground level.
Therefore,
Potential energy = PE = mgh
This potential energy is a result of gravity pulling downwards. The gravitational constant, g, is the acceleration of an object due to gravity. This acceleration is about 9.8 m s⁻².
<h2>
(3) Stored energy:</h2>
Stored energy is a Potential energy.
Hence, the only energy which is not a thermodynamic energy is option (a) Utilization energy.
