For the given question above, there are other details that is missing. Here is what I got from my research.
Mass of a hydrogen atom as 1.008 u,
<span>where 1 u=1.661 times 10^-27 kg.
</span>The frequency of a mass on a spring is:
<span>f = omega / 2pi = sqrt (k/meff) / 2pi </span>
<span>The meff you use is the effective mass. If two bodies with mass M and m are both free to move: </span>
<span>Meff = Mm / (M+m) </span>
<span>If M=m, then Meff = m/2 (as you were given) </span>
<span>So the answer is: </span>
<span>f = sqrt (2k/m) / 2pi </span>
Answer:
The correct answer is
d. heating evaporative cooling and mineral transport
Explanation:
Plants transpire to expel excess heat energy by a process known as evaporative cooling. As the water involved in transpiration evaporates, heat energy is transferred from the plant system into the surrounding environment cooling down the plant.
During transpiration, the stomata of the plant are open allowing the outward flow of the evaporated water and also the open stomata enable the plant to absorb carbon dioxide (CO2) from the atmosphere. The carbon dioxide is required in photosynthesis for the formation glucose while producing oxygen as well.
The water also transports nutrients dissolved in it as it is being transported to the leafs for evaporation. These nutrients are thus delivered tm all parts of the plant.
By discovering calculus, Sir Issac Newton contributed to the field of mathematics.
<u>Explanation:</u>
In the early history, infinitesimal calculus, are a mathematical discipline that focuses on boundaries, derivatives, functions, infinite sequences and integrals. The work of Newton analysis began with finding the slope of any points in curve, the slope of which is constantly changing. By this way, named ‘method of fluxions’ the derivative to find the slope instead of differentiation.
This is due to the fact that he calls the "fluxion" and "fluent" variable of x and y at the instantaneous rate of curve change. He then concluded that the opposite of differentiation is integration, which he called the "method of fluents". This enabled him to develop the first fundamental calculus theorem, which states that if the function is integral and then differentiable, the basic function can be retained because differentiation and integration are inverse functions.
Newton did not publish anything about the analysis until 1693, but the mathematician Leibniz from Germany published his theory version in 1684. In addition to working on universal gravity, Newton developed three laws of motion that constitute the basic principles of modern physics. His discovery led to the development of stronger solutions to mathematical problems.

I might be wrong but I’d say the first one
Answer:
•when a food service worker touches food
Explanation:
The worker is physically putting his hands on the food, therefore contaminating it which whatever’s on his hands
