Explanation:
Given that,
Altitude 
We need to calculate the radius
Where, R = radius of the earth
h = radius of altitude
Put the value into the formula
(a). We need to calculate the period of the orbit,
Using formula of period
(b). We need to calculate the speed of the satellite
Using formula of speed
Put the value into the formula
(c). We need to calculate the acceleration of the satellite
Using formula of acceleration
Put the value into the formula
Hence, This is the required solution.
wings
Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air.
Answer:
Aristotle believed that matter was made of tiny particles.
Explanation:
''Aristotle vehemently opposed the Atomic theory developed by Democritus. He believed that instead of being matter being made of tiny particles (atoms) that they were all fundamentally air, fire, water, and earth.''
the answer to the question is a metallic conductor with free electrons surrounded by a rubber insulator lacking free electrons
Answer:
the answers the correct one is cη
Explanation:
In this simple pendulum experiment the student observes a significant change in time between each period. This occurs since an approximation used is that the sine of the angle is small, so
sin θ = θ
with this approach the equation will be surveyed
d² θ / dt² = - g / L sin θ
It is reduced to
d² θ / dt² = - g / L θ
in which the time for each oscillation is constant, for this approximation the angle must be less than 10º so that the difference between the sine and the angles is less than 1%
The angle is related to the height of the pendulum
sin θ = h / L
h = L sin θ.
Therefore the student must be careful that the height is small.
When reviewing the answers the correct one is cη
