Compared with our sun, first-generation stars tend to be __ in mass and _

1 answer:

3 0

<span>These stars tend to be much larger and much hotter than our sun. This is because they have more hydrogen with which to fuse into helium, and this increased level of fuel keeps the overall temperature more elevated than our own star. Over time, the temperature, brightness, and size will decrease as the amount of fuel decreases.</span>

World oil reserves amount to about 10,000 EJ, and humankind uses energy at the rate of roughly 18 TW. If all our energy came fro

Volgvan

Answer:

t=17.61 years.

Explanation:

Given that

Reserve of energy = 10,000 EJ

Energy used by human = 18 TW

We know that

$1\ E= 10^{18}$

$1\ T= 10^{12}$

$Reserve\ of\ energy = 10,000 \times10^{18} J$

$Reserve\ of\ energy = 10^{22} J$

$Energy\ used\ by\ human = 18 \times10^{12}\ W$

Lets t time after energy will be exhaust

$18 \times10^{12}\times t=10^{22}$

$t=\dfrac{10^{22}}{18 \times10^{12}}\ s$

$t=5.55\times 10^8 \ s$

We know that

1 year = 365 days

1 year = 365 x 24 hr

1 year = 365 x 24 x 3600 s

$1year =3.15\times 10^7\ s$

$t=\dfrac{5.55\times 10^8 }{3.15\times 10^7}$

t=17.61 years.

Why is London, United Kingdom,farther north than Ottawa, Canada, yet it has a warmer climate than Ottawa?

Alisiya [41]

So there's actually two answers to this question. The Gulf Stream is part of the reason why Britain is warmer, since it carries so much warm water, but the difference between a maritime and a continental climate is more important. At the latitudes of Canada and Britain, the prevailing winds are coming from the west. If you're in the east, the prevailing winds are gonna have to travel all the way across the ocean, which will lead to it being warmer in the winter, and colder in the summer. If you've got thousands of miles of continent out to windward, your climate will be more extreme. If you're going across the entire ocean, it's gonna be more mild, and predictable. Continents just get hotter and colder than oceans, and this affects the temperature of the atmosphere passing over them.
