Answer:
Correct answer is b) convex mirror
Explanation:
A convex mirror, which bulges outward, reflects at a wider angle near its edges than at its center, creating a slightly distorted image that's smaller than actual size. Convex mirrors have many uses. The smaller size of the images means that you can see more with these surfaces, hence their use in safety mirrors.
The chain reaction is easy to stop. Just add a neuron absorbing material. The Control Rods in rectors can do that You just SCRAM (put the rods all the way in) or add something like Boron and the chain reaction stops.
<span>The problem is the radioactive waste. Those isotopes break down and release heat spontaneously, no neutrons required. The only known way to stop or slow radioactive decay down is to slow time down by moving at relativistic speed or near orbit to a black hole.</span>
Answer
Commercial farming is a large-scale production of crops for sale, intended for widespread distribution to wholesalers or retail outlets.
Answer:
The difference is 2 pH units.
Explanation:
Let's give an arbitrary value to the H⁺ concentration of solution A, [H⁺]ₐ:
If that's the case then the pH of solution A would be:
----
The H⁺ concentration of solution B ( [H⁺]ₓ ) is 100 higher than that, so:
- [H⁺]ₓ = 0.001 * 100 = 0.1 M
And its pH:
So the difference in pH values is:
