(a) The speed of a satellite on a low lying circular orbit around this planet is 7,338.93 m/s.
(b) The minimum speed required for a satellite in order to break free permanently from the planet is 10,378.82 m/s.
(c) The radius of the synchronous orbit of a satellite is 69,801 km .
<h3>Speed of the satellite</h3>
v = √GM/r
where;
- M is mass of the planet
- r is radius of the planet
v = √[(6.67 x 10⁻¹¹ x 4.74 x 10²⁴) / (5870 x 10³)]
v = 7,338.93 m/s
<h3>Escape velocity of the satellite</h3>
v = √2GM/r
v = √[( 2 x 6.67 x 10⁻¹¹ x 4.74 x 10²⁴) / (5870 x 10³)]
v = 10,378.82 m/s
<h3>Speed of the satellite at the given period </h3>
v = 2πr/T
r = vT/2π
r = (7,338.93 x 16.6 x 3600 s) / (2π)
r = 69,801 km
Thus, the speed of a satellite on a low lying circular orbit around this planet is 7,338.93 m/s.
The minimum speed required for a satellite in order to break free permanently from the planet is 10,378.82 m/s.
The radius of the synchronous orbit of a satellite is 69,801 km .

Answer:
5.152 A
Opposite to the inner coil
Explanation:
= Vacuum permeability =
= Outer coil current
= Inner coil current = 5 A
= Turns in inner coil = 120
= Turns in outer coil = 165
= Inner radius = 0.012 m
= Outer radius = 0.017 m
Putting the magnetic field as equal we have
The magnitude of current is 5.152 A,
The direction of the current is opposite to that of the inner coil as they have opposing magnetic fields
Answer:3 seconds
Explanation:
Initial velocity(u)=10m/s
Final velocity(v)=25m/s
Acceleration(a)=5m/s^2
time=(v-u) ➗ a
time=(25-10) ➗ 5
time=15 ➗ 5
time=3
time is 3 seconds
A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement. This may seem a bit of a mouthful, but if you break it down it becomes simpler.
Minerals are naturally occurring
They are not made by humans
Minerals are inorganic
They have never been alive and are not made up from plants or animals
Minerals are solids
They are not liquids (like water), or gases (like the air around you)
Minerals have a definite chemical composition
Each one is made of a particular mix of chemical elements
Minerals have an ordered atomic arrangement
The chemical elements that make up each mineral are arranged in a particular way - this is why minerals 'grow' as crystals
Well, part of 'velocity' is the direction of the motion, and the graph doesn't give us any information about the direction. So the best we'll be able to do is find the average SPEED of the car.
On a distance/time graph, the speed is just the slope of the line. Since this graph is a straight line, it doesn't matter which points along the line you choose ... the answer will always be the same.
Average speed = (distance covered) / (time to cover the distance)
Let's use the ends of the line ... the origin, and the point at the top.
On the left side of the graph, we see the label 'Distance (m)', and I don't know what 'm' stands for. It could be 'miles' or 'meters'.
Anyway, the point at the top of the line shows that the car covered a distance of 25.0 'm' in 10.0 s of time.
Average speed = (25 m) / (10 s)
Average speed = (25/10) m/s
(I'm pretty sure that 'm' means 'meters' and 's' means 'seconds'.)
