How is luminosity affected by other characteristics of a star

1 answer:

6 0

Answer:As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.

a wrench weighs 5.24 newtons on earth. when it is taken to the Moon, where g =1.16 m/s2 how much does it weigh?

Andrew [12]

“Weight of the wrench” on “the moon” is “6.07 kg”.

Explanation:

Weight of the wrench is 5.24 N

Weight of the wrench in kilograms = W × g

Taken “g” on the moon is $1.16 \mathrm{m} / \mathrm{s}^{2}$

$=5.24 \mathrm{N} \times 9.81 \mathrm{m} / \mathrm{s}^{2}=51.352 \mathrm{kg}$

Weight of the wrench in kilograms is 51.352 kg.

Formula to calculate weight of the object on the moon is

$\frac{\text {weight of the object on earth}}{9.81 \mathrm{m} / \mathrm{s}^{2}} \times 1.16 \mathrm{m} / \mathrm{s}^{2}$

Substitute the values given,

$=\frac{51.352 \mathrm{kg}}{9.81 \mathrm{m} / \mathrm{s}^{2}} \times 1.16 \mathrm{m} / \mathrm{s}^{2}$

$=5.234 \times 1.16$

= 6.07 kg

Therefore, weight of the wrench on the moon is 6.07 kg.
