Answer:
Heat transport from Sun to Earth is accomplished primarily by electromagnetic radiation.
Explanation:
We define radiation as the transfer of energy by particles or waves (as in this case) in a material medium or empty space.
The Sun is a star that emits radiation in the electromagnetic spectrum. Approximately 49% of it is in the near infrared part, 43% in the visible part (light), 7% in the UV part and the 1% left is a mixture of radio and gamma waves and X-rays.
Of the Sun's energy that reaches Earth around 30% is reflected by the atmosphere and the Earth, around 20% is absorbed by clouds and approximately 50% is absorbed by land and sea.
Answer:
τ ≈ 0.90 N•m
F =
Explanation:
I = ½mR² = ½(10)0.5² = 1.25 kg•m²
α = ω²/2θ = 3.0² / 4π = 0.716... rad/s²
τ = Iα = 1.25(0.716) = 0.8952... ≈ 0.90 N•m
τ = FR
Now we have the unanswered question of reference frame.
80° from what?
If it's 80° from the radial
F = τ/Rsinθ = 0.90/0.5sin80 = 1.818... ≈ 1.8 N
If it's If it's 80° from the tangential
F = τ/Rcosθ = 0.90/0.5cos80 = 10.311... ≈ 10 N
There are an infinite number of other potential solutions
Answer:
Following are the solution to the given question:
Explanation:
For crashing speed, we can use energy conservation:
kinetic energy
potential energy
moon mass
Radius
Calculating the mass drop for the leave:
Solve the value for
The approach is correct but misrepresented in replacing 180 km instead of 110 km.
They have a charge of zero because every atom starts of with the same number of electrons (which are negative) and protons(which are positive.)
These happens in till bonding happens, but the bond itself is zero. Zero just means that the bond has the same amount of positive and negative.
Explanation:
m = kg. v=m/s. g=m/s^2. h= m
>>1/2mv^2=mgh
>>1/2mv^2=mgh>> kg*(m/s)^2= kg*m/s^2*m
>>1/2mv^2=mgh>> kg*(m/s)^2= kg*m/s^2*m>>kg m^2/s^2=kg m^2/s^2 the fraction 1/2 won't be able to make any changes to to the dimensional expression of energy i.e half of energy is still energy therefore you can neglect the number .
