Answer:
Energy is defined as the ability to do work. Forms of energy could be kinetic energy or potential energy. Thermal or heat energy can originate from a hot object such as the sun. Energy is used to produce work. Electrical energy for lighting purposes and heating in homes and factories.
Explanation:
Energy is defined as the ability to do work and can be in various forms such as kinetic energy, potential energy, thermal, chemical, electrical energy etc.
Energy origination depends on the type of energy form in discussion. Thermal or heat energy can originate from a hot object such as the sun or an iron box, chemical energy originates from the interaction of atoms and molecules and electrical energy can be initiated by movements of electrons.
Energy is used to produce work. Different forms of energy can do different tasks such as;
Heat energy for heating water
Electrical energy for lighting purposes
Geothermal energy for producing heat and electricity
Nuclear energy for production of nuclear power
Chemical energy for facilitating chemical reactions
(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 .

#SPJ1
Answer:
2.000 s
Explanation:
Given:
a = 50.00 m/s²
v = 100.0 m/s
v₀ = 0 m/s
Find: t
v = at + v₀
(100.0 m/s) = (50.00 m/s²) t + (0 m/s)
t = 2.000 s
(1100 ft/sec) x (1 mile / 5280 ft) x (3600 sec / 1 hr)
= (1100 x 3600 / 5280) mile/hour
= 750 miles per hour .
Answer:
Copper is the correct answer
Explanation:
Copper is very strong in situations where it is put in place and not stressed. Like all metal products, you can tear a whole in a copper pipe when it is under constant stress. That might seem obvious, but the thing about using it as pipe material is that some people try to cheat and bend copper into place if they don't measure properly and wind up with a piece that is bit too big or a bit too small.
