jenyasd209 [6]

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

v_{21}=v_{2}-v_{1}

Put the value into the formula

v_{21}=12-3

v_{21}=9\ km/h

The distance is 200 m.

We need to calculate the time

Using formula of time

v=\dfrac{d}{t}

t=\dfrac{d}{v}

Put the value into the formula

t=\dfrac{200}{9\times\dfrac{5}{18}}

t=80 sec

Hence, The time of oil tanker will be 80 sec.

How do the rates at which land and water heat up eventually cause the predictable movement of air
NNADVOKAT [17]
Land and water differ into the absorption and releasing of heat, the land heats up quicker than the water, and the land also cools off quicker than the water. So when the air is hotter over the land (during the day), then the air masses are moving from the sea to the land cause they are cooler and heavier. When the air is cooler over the land (during the night), then the air masses move from the land towards the water.
