Answer:
Tundra Biome
Explanation:
Permafrost is a type of soil that is frozen all year round. It consists of rocks, soils and ice. The ice or frost holds the earth materials together.
The tundra biome lies below the arctic circle close to the north pole. Most of the earth here is predominantly frozen all year round. A layer of glacier covers the surface and a deep lying layer of permafrost follows suit.
Some mountain tops capped with ice shows this tundra features.
Most tundras are termed cold deserts as they have little to no precipitation all year round. There is absence of vegetation cover as a result of low growing season of the plants.
The blades must be angled to be able to create the lift, and the blades need an engine powerful enough to spin the blades fast enough to create adequite lift. This remindes me of Newton's third law! For every action, there is an oposite reaction
Answer:
ΔT = 78.32 °C
Explanation:
Kinetic energy of bullet is K
K = mv²/2
= .004 * ( 200 m/s )²/2
= 80 J
Half of the heat E = 40 J
Now a per the equation of energy transferred ,
E = cm ΔT
c is the specific heat of latent, m is the mass and ΔT is the change in temperature.
ΔT = 40 / ( .0305 × 4186 × .004)
ΔT = 78.32 °C
Im pretty sure its neptune. Its mot pluto because its not a planet. Good luck.
Answer:
Explanation:
Weight is actually a force. A force can change depending on its location. A mass remains constant no matter where it is.
A)
F = m * a
m = 250 kg
a = 9.81 m/s^2
F = 250 * 9.81 = 2452.5 N
B)
The acceleration due to gravity on the moon is roughly 1/6 what it is on earth. You can check its value in your notes.
a = 9.81 + (1/6) = 1.635
m = 250
F = 250 * 1.635
F = 408.75
C)
The mass is the same anywhere in the universe.
250 kg
