Answer:
autotrophs and heterotrophs. Autotrophs (producers) use energy directly from the sun or from chemicals to produce organic molecules. Photoautotrophs such as plants use energy from sunlight to make organic compounds by photosynthesis.
Answer:
L = 2.83 J.s
Explanation:
The formula for the angular momentum of the stone is given as follows:
L = mvr
where,
L = angular momentum of the stone = ?
m = mass of the stone = 0.1 kg
v = linear velocity of the stone = rω
r = radius of circular path = 1.5 m
ω = angular speed of the stone = (2 rev/s)(2π rad/1 rev) = 4π rad/s
Therefore,
L = mvr = m(rω)r
L = mr²ω
using values, we get:
L = (0.1 kg)(1.5 m)²(4π rad/s)
<u>L = 2.83 J.s</u>
yes because your mass doesn't change but your weight can
ex- if you travel to Saturn your weight would change but your mass would stay the same
Answer: slow revolution and fast rotation
Solar system has 8 planets. 4 inner rocky planets - Mercury, Venus, Earth and Mars and 4 outer gaseous planets - <u>Jupiter, Saturn, Uranus and Neptune.</u> The outer planets have few common features.
They are gaseous. There period of revolution is larger than the inner planets which means that they have slow revolution about the Sun. One day on the outer planets is smaller than the inner planets which means they have fast rotation.
<u>For example,</u> Jupiter has revolves around sun in 11.86 Earth years and rotates about axis in 9.8 Earth hours. Uranus revolves around sun in 84 Earth years and rotates on its axis 17.9 Earth hours.
