Answer:

F-type star

Explanation:

Stars are classified on the basis of temperature and luminosity in the H-R diagram.

Based on the temperature, the stars classified as:

O, B, A, F, G, K, and M.

O-type stars are the hottest stars and M-type stars are the coolest ones.

A star having temperature 6000 K and luminosity 1000 would be a F-type star.

Luminosity depends on temperature and size of a star. More the temperature, more would be its luminosity.

How many estimates are used in the calculation of depreciation?

xeze [42]

Answer:

Two estimates

Explanation:

There are mainly two estimates used in the calculation of depreciation such as the useful life and the salvage value of an asset. The salvage value is defined as the predicted amount that will be obtained by a company from an asset when it is disposed at the end of the useful life of the particular asset. On the other hand, the useful life commonly refers to the estimation of how long the asset is useful for the company. This is different from the lifespan of the asset.

When heating water, during what temperature range will the temperature cease to change for some time?

Morgarella [4.7K]

Answer: Option (B) is the correct answer.

Explanation:

As we know that the temperature when the vapor pressure of liquid becomes equal to the atmospheric pressure surrounding the liquid. And, during this temperature liquid state of substance changes into vapor state.

But during this process of change in state of substance the temperature will cease to change for some time because unless and until all the liquid molecules do not convert into vapor state the temperature will not rise or change.

As the boiling point of water is $100^{o}C$ so the temperature ceases to change from $98^{o}C$ to $102^{o}C$ .

Therefore, we can conclude that when heating water, during $98^{o}C$ to $102^{o}C$ temperature range the temperature will cease to change for some time.

Grace [21]

Answer:

Only the 4 th statement is true that is bed 1 and 3 are older than 4.

Explanation:

The 5 beds are numbered from 1 to 5 , 1 being the lowest and 5 being the topmost bed.

We are given 4 statements and we have to find out which all are true.

(a)Bed 4 is older than bed 2

This is wrong because the lower beds are older than beds that are higher.

(b)Bed 3 is older than beds 2 and 4

This is also wrong because the 2 is older than 3

(c)Bed 5 is the oldest

This is wrong because bed 1 is the oldest

(d)Beds 1 and 3 are older than 4

This is true as lower beds are older

A skydiver jumped out of a plane, determine distance he distance he descended after 5 seconds. Gravity is pulling him down at 10

Bond [772]

The distance travelled in 5 seconds is 125 m

Explanation:

The motion of the skydiver is a free fall motion, since he is acted upon the force of gravity only. Therefore, it is a uniformly accelerated motion, with constant acceleration downward, and we can find the distance he travels by using the following suvat equation:

$s=ut+\frac{1}{2}at^2$
