The lab coat is not thick enough to protect you from ionizing radiation.
<h3>What is radiation?</h3>
Radiation is a form of energy that we can not see with our optical eyes. We know that radiation could have a damaging effect on the body. The sort of radiation that could have a damaging effect on the body is what we call ionizing radiation.
We know that an ionizing radiation could only be stopped by a thick vest such as a lead coat. If you are wearing a lab coat, you are not safe because the lab cat is not thick enough to protect you from ionizing radiation.

Answer:
A
Explanation:
Chickens are birds and they lay hard shelled eggs
Penguins are birds and lay hard shelled eggs
Answer:
The mass is also half of the mass of the original piece
Explanation:
Recall that the volume of a substance is defined as mass/volume. The density of substances is a constant. Hence, if a break off a piece of cement or bread such that what remains is only half the volume of the original piece, the mass of the new piece must also reduce to half of the mass of the original piece so that the volume of the material will remain constant.
Hence the answer above.
Answer:
1.87 J
Explanation:
q = c x m x (T2-T1)
c- specific heat of water (4.186 j/g.C)
q = 4.186 x 0.5137 x 0.871 = 1.87 J
Convection
Explanation:
Convection is form of heat transfer by which heat moves through liquid and circulates due to density differences.
There are three major forms of heat transfer:
- Conduction is form of heat transfer that involves contact between two bodies in which collision between their molecules caused heat exchange from the hot body to the cold one.
- Radiation is a form of heat transfer that does not involve contact. It involves the use of electromagnetic waves of different forms.
- Convection occurs in fluids in which heat transfers as a result of movement of molecules of the medium from one point to the other. The hotter body becomes lighter and rises whereas the colder ones sinks.
