We have the following values used to solve this:
For ⁴₂He:
No of protons: 2
No of neutrons : 2
Mass of proton: <span>1.00728 amu
Mass of neutron: </span><span>1.00867 amu
Atomic mass: </span><span>4.002603 amu
The formula to solve for the mass defect is:
md = (mp + mn) - mo
md = (2x</span>1.00728 + 2x1.00867) - 4.002603
md = 0.029297
Therefore, the mass defect is 0.029297 amu
Answer:
19.98Joules
Explanation:
Energy possessed by the body is the kinetic energy
Kinetic Energy = 1/2mv²
m is the mass
v is the velocity
For the 4kg moving at 6m/s
kE = 1/2 * 4 * 6^2
KE = 1/2 * 4 * 36
KE = 72Joules
For the 4kg moving at 5.1m/s
kE = 1/2 * 4 * 5.1^2
KE = 1/2 * 4 *26.01
KE = 52.02Joules
Amount of Energy lost = 72 - 52.02
Amount of Energy lost = 19.98Joules
Hence the amount of Energy lost is 19.98Joules
The nearby magnet and the electric current both will.
Answer:
Well depending on who you are and what your personality type is then you could be just as involved and still not liking the sport. Some people will still pay just as much attention because they would not want to be a poor sport.

Can I have Brainliest please
Answer:
The answer is letter C, The energy of the supersaturated liquid is converted to heat as the compound crystallizes.
Explanation:
"Hand warmers" are very essential when the cold season comes. It provides warmth to the hands, especially when going outdoors. There are different kinds of hand warmers, such as the<em> "reusable hand warmer." </em>In contrast to air-activated hand warmers, the reusable hand warmers contain sodium acetate (not iron).
Sodium acetate is a "supersaturated liquid." This means that is has more substances dissolved in it. So, when this crystallizes, heat is released. Remember that crystallization is considered an "exothermic process." This means that the process releases energy (in this case, through "heat").
Thus, this explains the answer, letter C.
