The majority of heat that the cooling system receives from the engine is wasted.

Option A

<u>Explanation:</u>

The cooling system is used in almost all vehicles to cool down the engine before it overheats and gets damaged. A cooling system also helps in maintaining the right temperature of the engine when the overall temperature declines in the winters. There are two major types of cooling systems: Air and Water or fluid-based.

The fluid-based cooling systems are more efficient in cooling the vehicles having Internal combustion engines. In this, a liquid coolant travels through various tubes and absorbs the heat from the engine, this heat is then released in the atmosphere through the radiator. This heat is regarded as wasted because it can be utilized in many ways but currently it is not harnessed properly.

While trees are not the largest level in the pyramid of numbers, they are still the base for both the pyramids of biomass and py

eimsori [14]

Answer:

TRUE

Explanation:

The trees are the primary producers that produces the food on which the consumers are dependent. This forms the base of the ecological pyramid for both energy as well as biomass.

In any biological condition, it can be observed that during its ecological succession from one trophic level to the next, almost 90% of its total energy is lost, and only 10% of its energy is transferred to the successive trophic level.

Similarly, biomass is also comparatively higher in producers like plants and trees than in any other trophic levels.

Thus, the given statement is True.

Let A and B be events with P(A) = 0.61 and P(A ∩ B) = 0.39. For what value of P(B) will A and B be independent?

timofeeve [1]

Answer:

$P(B) = 0.64$

Explanation:

Given

$P(A) = 0.61$

$P(A\ n\ B) = 0.39$

Required

Determine P(B)

If A and B are independent, then:

$P(A\ n\ B) = P(A) * P(B)$

Substitute values for P(A) and P(A n B)

$0.39 = 0.61 * P(B)$

Make P(B) the subject

$P(B) = \frac{0.39}{0.61}$

<em /> $P(B) = 0.64$ <em> --- approximated</em>

If an angle of a parallelogram is two-third of its adjacent angle, the smallest angle of the parallelogram is.

Harrizon [31]

If an angle of a parallelogram is two-third of its adjacent angle, then the smallest angle of the parallelogram is 72°. Adjacent angles exhibit a common side and a corner point.

Adjacent angles exhibit a common side and a corner point, although they do not overlap.

A parallelogram can be defined as a simple type of quadrilateral having two pairs of parallel sides.

A rectangle can in turn be defined as a parallelogram having four right angles (90°), thereby all rectangles represent quadrilaterals.

The sum of the adjacent angles of a parallelogram is equal to 180°.

In this case, we have that the sum of adjacent angles >> X + 2/3 X = 180° >> X = 108° >> 2/3 X = 72°
