Answer:
It will decrease because the marginal productivities of workers will decrease. Diminishing marginal product occurs when the marginal product of an input goes down as the quantity of the input goes up. The transformation in product resulting from employing one more unit of a particular input for instance, the change in output when a firm's labor is mark up from five to six units, assuming that the mass of other product are kept constant is called The input of marginal product or marginal physical product.
Explanation:
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

Answer:
Δλ = 3*10⁻³ m.
Explanation:
- At any wave, there exists a fixed relationship between the speed of the wave, the wavelength, and the frequency, as follows:
where v is the speed, λ is the wavelength and f is the frequency.
- Rearranging terms, we can get λ from the other two parameters, as follows:
- Since v is constant for sound at 343 m/s, we can find the different wavelengths at different frequencies, as follows:
- The difference between both wavelengths, is just the difference between (3) and (4):
⇒ Δλ = 3*10⁻³ m.
Answer:
Mass
Explanation:
The mass of an object expresses the amount of matter it comprises. Which implies that objects with higher mass contains higher matter compared to objects with lesser masses. Thereby it determines the measure of inertia experienced by an object when a force is applied to change its direction of motion, or to set it in motion when at rest, or bring it to rest when in motion.
The mass of an object the same no matter its location, and it is measured in kilograms.
Answer:
Ea = 112500[J]
Eb = 87500[J]
Explanation:
To solve this problem we must use the principle of energy conservation which tells us that the energy of a body plus the work done or applied by the body equals the final energy of a body.
This can be easily visualized by the following equation:
Now we must define the energies at points A & B.
<u>For point A</u>
At point A we only have kinetic energy since it moves at 15 [m/s]
So the kinetic energy
The final kinetic energy can be calculated as follows:
