Answer:
g = 4.7 ×
m/
Explanation:
Given that the mass of the satellite = 700 kg, and 10,000 m above the earth;s surface.
From Newton's second law,
F = mg ............... 1
From Newton's gravitation law,
F =
.................. 2
Where: F is the force, G is the gravitational constant, M is the mass of the first body, m is the mass of the second body, g is the gravitational force and r is the distance between the centers of the two bodies.
Equate 1 and 2 to have,
mg = 
⇒ g = 
But; G = 6.67 ×
N
, M = 700 Kg, r = 10000 m
Thus,
g = 
= 
= 4.669 ×
m/
The force of gravity on the satellite is 4.7 ×
m/
.
The answer is B. A and C. Spring tides occur during a new moon and full moon
The correct answer for the question that is being presented above is this one: "<span>c. Planets orbit in elliptical patterns; a planet's orbit covers equal areas in equal amounts of time; planets' orbits are shorter or longer depending on their distance from the Sun."</span>
Here are the following choices:
a. Planets orbit in elliptical patterns; the bigger the planet, the more gravitational pull; a planet's gravitational pull is stronger or weaker depending on its distance from the Sun.
b. A planet's orbit covers equal distances in equal amounts of time; the speed of a planet's orbit depends on its distance from the Sun; the bigger the planet, the slower it moves.
c. Planets orbit in elliptical patterns; a planet's orbit covers equal areas in equal amounts of time; planets' orbits are shorter or longer depending on their distance from the Sun.
Answer:
A. 100 Watts
B. 12 Watts
C. the first bulb
Explanation:
A. The formula for power is Work done/time
6000J/60seconds = 100J/s or 100W
B. Another formula for power is Current * Voltage
0.05*240 = 12W
