Answer:
115911.09915 J
Unchanged
Decreased
Explanation:
m = Mass of motorcycle = 180 kg
v = Velocity of motorcycle = 9 m/s
F = Force = 400 N
s = Displacement = 300 m
= Angle above the horizontal = 15°
Work done is given by

The work done is 115911.09915 J
It can be seen that the force applied is constant so it does not matter if the speed of the motorcycle changes.
Tension on the rope would be

Work done

So, the work done would be reduced.
Answer:
r = 4.24x10⁴ km.
Explanation:
To find the radius of such an orbit we need to use Kepler's third law:

<em>where T₁: is the orbital period of the geosynchronous Earth satellite = 1 d, T₂: is the orbital period of the moon = 0.07481 y, r₁: is the radius of such an orbit and r₂: is the orbital radius of the moon = 3.84x10⁵ km. </em>
From equation (1), r₁ is:
Therefore, the radius of such an orbit is 4.24x10⁴ km.
I hope it helps you!
Wooden desk it doesn’t conduct or absorb heat as much as metal or plastic
It looks like you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer generally as the ℓ quantum number increases the energy is slightly higher. As a result 2s and 2p are no longer identical in energy in atoms<span> with more than one electron.</span>
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
The total thermal power generated by this plutonium source is determined as 5.65 J/s.
<h3>Total thermal power generated</h3>
The total thermal power generated by this plutonium source is determined as follows;
ΔP = Eλ
where;
- E is the energy of the particles = 5.6 mev
- λ is the activity of the plutonium, which should be = 6.3 x 10¹⁵ s⁻¹
ΔP = (5.6 mev) x (6.3 x 10¹⁵ s⁻¹)
ΔP = (5.6 x 10³ x 1.6 x 10⁻¹⁹ J) x (6.3 x 10¹⁵ s⁻¹)
ΔP = 5.65 J/s
