I would say the correct answer is nighttime. The clouds in the atmosphere would absorb the radiation that is emitted by the Earth and at at night 30% of these would be radiated back to the Earth's surface. Hope this answers the question. <span />
Wood, marble, clay, terracotta and even concrete all come in colors and can be classified as natural materials.
Answer:
<em>The mass of the apple is 0.172 kg (172 g)</em>
Explanation:
<u>The Law Of Conservation Of Linear Momentum
</u>
The total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and speed v is
P=mv.
If we have a system of two bodies, then the total momentum is the sum of both momentums:
If a collision occurs and the velocities change to v', the final momentum is:
Since the total momentum is conserved, then:
P = P'
Or, equivalently:
If both masses stick together after the collision at a common speed v', then:
We are given the mass of an arrow m1=43 g = 0.043 kg traveling at v1=84 m/s to the right (positive direction). It strikes an apple of unknown mass m2 originally at rest (v2=0). The common speed after they collide is v'=16.8 m/s.
We need to solve the last equation for m2:
Factoring m2 and m1:
Solving:
Substituting:
The mass of the apple is 0.172 kg (172 g)
<u>Venus </u><u>and </u><u>Uranus</u> are exception to these rules.
Venus rotates in the horizontal course when Uranus falls as it circles the solar on its aspect.Venus, like the different stars, at the beginning rotates anticlockwise however it nevertheless does.The exceptions are Venus and Uranus but they've what's called regressive rotation, rotating parallel to the solar's roster.
Uranus is the<em> 7th planet</em> from the sun. Its call is a connection with the Greek god of the sky, Uranus, who, in step with Greek mythology, turned into the exceptional-grandfather of Ares, grandfather of Zeus and father of Cronus. It has the<em> third-largest planetary </em>radius and <em>fourth-largest </em><em>planetary mass</em><em> </em>in the solar system.

Answer:
The answer is "Choice B and Choice C".
Explanation:
In this question, the two features, which make electromagnetic waves effective for interaction, which they don't really need a method of travel of data and move information quite fast. The motion among magnetic and electrical forces is generated by electromagnetic radiation. These waves will spread without the need for a source for their movement, and they have high speed and also the electromagnetic waves it has the same frequency as light.
