Answer : Relatively hot objects
Explanation : We know that, the temperature of the objects is inversely proportional to their wavelengths. The objects emitting radiation in the visible region have short wavelength and hence are relatively hotter.
We know the range of wavelength of the visible spectrum is from 400 nm to 780 nm.
I believe the answer would be zero because the q1 and q2 are equal on opposite sides and it
hope this helps
Mechanical waves need material stuff to travel through.
They cannot travel through vacuum.
That's why we can't hear the explosions on the sun.
That's also why astronauts standing on the moon or working outside the Space Station have to use radio to talk to each other, even if they're only a few inches apart. There's no air between them, or any other material stuff. So sound can't travel between them.
Answer:
Summarized
Explanation:
Among the many hypotheses proposed for the origin of the moon the four main are summarized as
the fission hypotheses in which moon was once a part of earth but got separated due to collision. The second hypotheses is that the moon formed along with the Earth but independently.Moon was formed else where in the solar system and got captured by the Earth's gravitational pull. The newer giant impact hypotheses suggest that a mars sized object grazed Earth, Ejecting material from both Earth and itself, that material condensed to form moon.
The answer:
we can use newton's second law for finding the value of acceleration
that is F=MxA
M the mass
A is the acceleration
F= P-Fk, Fk= -Mgcosθμ and P=Mgsinθ
μ is the coefficient of friction
The value of μ can be found with the above condition
(<span>pulled up a 28 ° rough ramp at constant speed)
</span>this implies the acceleration is equal to zero
100N - mgsin(28°) -mgcos(28°)μ<span> = 0 , from where </span>
μ= [100N - mgsin(28°)] / mgcos(28°)
μ=0.2
and then,
F=MxA= Mgsinθ -Mgcosθμ finally A=gsin28° -gcos28° x0.2 =2.6m/s²
