Answer:
The time of oil tanker will be 80 sec.
Explanation:
Given that,
He walks at 3 km/hour.
If the container ship is 100 m long, and travelling at 12 km/hour.
The distance will be 200 m.
We need to calculate the relative velocity
Using formula of relative velocity

Put the value into the formula


The distance is 200 m.
We need to calculate the time
Using formula of time


Put the value into the formula


Hence, The time of oil tanker will be 80 sec.
Answer: Limited Surface area - Volume ratio
Explanation:
Cells in various organisms usually have the same size be it a blue whale or an earthworm, a Human or a mouse or an Elephant and a squirrel. This is down to the way the cell is structure.
The Cell needs to absorb nutrients to survive while getting rid of waste material. For that to happen it needs an adequate surface area. The problem is that as the cell absorbs more nutrients thereby increasing in volume, this rise in volume occurs at a faster rate than the cell can increase its surface area so the surface area will keep shrinking.
Therefore, in order to have enough surface area to keep up the process of absorption and excrement, the cell will stop growing at the certain point and this process is similar in most if not all organisms.
Answer:
A. y = 6x + 10
Explanation:
Tangent line is just the point-slope formula. So your goal is to find the slope and the point (x₀, y₀) to plug into the equation.
The slope could be found by plugging in the derivative.
The (x₀, y₀) could be found by plugging in the original equation.
Answer:
a.)
Operant conditioning -
It is a type of learning in which a person learns from consequences ( which may be positive or negative ) that follows person's behavior.

For example - If Ryan is eating with dropping off the food and Jim or Kelly yells at Ryan for his bad behavior.
Negative Punishments -
If Ryan eats with dropping off his food from the plate , it will be discouraging for him if Jim and Kelly removing any good thing in which Ryan is comfortable.
For example - Ryan's watching TV time reduced or taken away his toys.
