The upper temperature range for stars is : c. 40,000 K

Every object has their own upper and lower temperature
This indicate the maximum possible energy that a star could release to its surrounding if its somehow exploded.

An object with a mass M = 250 g is on a plane inclined at 30º above the horizontal and is attached by a string to a mass m = 150
malfutka [58]

Answer:

0.495 m/s

Explanation:

T = tension force in the string connecting the two objects

M = Mass of the object on inclined plane = 250 g = 0.250 kg

m = Mass of the hanging object = 150 g = 0.150 kg

a = acceleration of each object

From the force diagram, force equation for the motion of the object on the inclined plane is given as

T - Mg Sin30 = Ma\\T = Mg Sin30 + Ma

From the force diagram, force equation for the motion of the hanging object on the inclined plane is given as

mg - T = ma\\T = mg - ma

Using the above two equations

Mg Sin30 + Ma = mg - ma

(0.250)(9.8) Sin30 + (0.250) a = (0.150) (9.8) - (0.150)a

a = 0.6125 ms^{-2}

h = height dropped by the hanging object = 10 cm = 0.10 m

v = Speed gained by the object

Speed gained by the object can be given as

v = sqrt(2ah)\\v = sqrt(2(0.6125)(0.20))\\v = 0.495 ms^{-1}

What nonliving materials are important to living things?
Pavel [41]
<span>Nonliving things also have unlimited duration of existence. While living things die and decompose, nonliving things such as rocks, mountains, air and water have existed for millions of years. They may grow, but they do so only by accretion, which is the process of growth by accumulating added layers of matter.</span>
