The answer is adequate nutrition, regular physical activity, and practical ways to reduce calories while retaining important nutrients.
Explanation:
Despite that adequate nutrition, regular physical activity, and practical ways to reduce calories while retaining important nutrients is one of the best strategy to reducing weight, most time it is very difficult for those that want to reduce or control their weight to discipline themselves enough to follow these routine. But one an individual that want to loose weight or live a healthy lifestyle is able to follow these procedures he/she will surely loose weight.
Answer:
4.2 is the answer
Explanation
The image formed in a plane mirror is an equal distance behind the mirror as the object in front of it.
Step 1: the equation to this problem would be: 8.4/2
Step 2: 8.4 ÷ 2 = 4.2
Answer:
The solute is oxygen
The solvent is water
Explanation:
A solvent is any chemical substance that dissolves other chemical substances, while a solute refers to any chemical substance that dissolves in other chemical substances. The best way to know when a chemical substance dissolves in another chemical substance is when a solid or gas dissolves in water. The solid or the gas can now be referred to as the solute and it will be shown to be in the the aqueous state, while the solvent is usually shown to be in the liquid state in any chemical equation.
Let us use the particular example of the dissolution of oxygen gas in water as shown below;
O2(g) + H2O(l)⇄O2(aq) + H2O(l)
The aqueous oxygen is the solute while the liquid water is the solvent.
Also, the substance having a smaller mass must be the solute and the substance having the larger mass must be the solvent.
Answer:
B. A rubber band is stretched out
Explanation:
Answer:
4.635 *10^12 Neutrinos
Explanation:
Here in this question, we are to determine the number of neutrinos in billions produced, given the power generated by the proton-proton cycle.
We proceed as follows;
In proton-proton cycle generates 26.7 MeV of energy and in this cycle two neutrinos are produced.
From the question, we are given that
Power P = 9.9 watts = 9.9 J/s
Watts is same as J/s
The number of proton-proton cycles required to generate E energy is N = E / E '
Where E ' = Energy generated in proton-proton cycle which is given as 26.7 Mev in the question
Converting Mev to J, we have
= 26.7 x1.6 x10 -13 J
To get the number N which is the number of proton-proton cycle required, we have;
N = 9.9 /(26.7 x1.6 x10^-13) = 2.32 * 10^12
Since we have two proton cycles( proton-proton), it automatically means 2 neutrinos will be produced.
Therefore number of neutrions produced = 2 x Number of proton-proton cycles = 2 * 2.32 * 10^12 = 4.635 * 10^12 neutrinos
