Answer:
why should we do , do by your own , no sense
Explanation:
1.) core- the central region where nuclear reactions consume hydrogen to form helium
2.) radiative zone- the section of solar interior between the innermost core and the outer convective zone.
3.) convection zone- where light (photons) is created.
4.) photosphere- the visible surface of the sun that we are most familiar with
5.) chromosphere- second most outer layer of the sun. due to low density it is relatively transparent and only apparent during eclipses.
6.) corona- an aura of plasma that surrounds the sun and other stars but is usually hidden by the bright light of the sun’s surface.
Answer:
I = 0.287 MR²
Explanation:
given,
height of the object = 3.5 m
initial velocity = 0 m/s
final velocity = 7.3 m/s
moment of inertia = ?
Using total conservation of mechanical energy
change in potential energy will be equal to change in KE (rotational) and KE(transnational)
PE = KE(transnational) + KE (rotational)
v = r ω
I = 0.287 MR²

Answer:
3 kg
Explanation:
Momentum before = momentum after
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
After jumping on the skateboard, the student and the skateboard have the same velocity, so v₁ = v₂.
m₁u₁ + m₂u₂ = (m₁ + m₂) v
(47.4 kg) (4.2 m/s) + m (0 m/s) = (47.4 kg + m) (3.95 m/s)
m = 3 kg
