The complex balancing act between a satellite's forward speed and the gravitational force pressing upon it prevents satellites in orbit from falling to the ground or shooting off into space.
When a satellite is put into orbit, it reaches a fast enough speed to escape the Earth's gravitational attraction.
By continuously falling towards the Earth and moving forward at the same time, the satellite may maintain a stableorbit.
This motion results in a curved course, which causes the Earth to be in a constant state of freefall.
Although the satellite is constantly being drawn towards the Earth by gravity, its forward velocity prevents it from dropping.
Thus, satellites don't fall or break free into space and are kept in a stable orbit.

b. High Renaissance
c. Late Renaissance
Answer:
The correct answer is option B, High Renaissance
Explanation:
The high renaissance period is the first half of the 16th century which marked its beginning from 1490s and ended by late 15th century. Some of the best known artist of this period were Michelangelo, Raphael, Bramante, Leonardo da Vinci etc. The period of existence of these artist was
a) Leobardo Da Vinci - 1452-1519
b) Michelangelo - 1475-1564
c) Raphael – 1483 -1520
Answer:
The correct answer is option B, High Renaissance
Explanation:
Answer:
Inertia
Explanation:
The tendency of an object to resist any change in its motion is known as its inertia. The first law of motion is also known as the law of inertia. The inertia of an object can change its speed and the direction of motion. It is related directly to the mass of an object.
A body having more mass will have more inertia while a body having less mas will have less inertia.
The kinetic energy of a moving body can be determined from its mass and velocity of the body. The kinetic energy of 1.0-kg billiard ball that moves at 5.0 m/s is 12.5 J. Hence, option D is correct.
Kinetic energy is a form of energy generated in body by virtue of its motion. It is directly proportional to the mass and square of velocity of the body. The equation of kinetic energy is written as follows:
KE = 1/2 mv²
When a body starts moving its kinetic starts to increase while the potential energy drops out. However the total mechanical energy in the system will be conserved.
The mass of the billiard ball is given 1 kg and the velocity is 5 m/s. Then the kinetic energy of the ball is calculated as follows:
KE = 1/2 1 kg × ( 5 m/s )².
= 1/2 × 25
= 12.5 J.
Therefore, the kinetic energy of 1.0-kg billiard ball that moves at 5.0 m/s is 12.5 J. Hence, option D is correct.

Answer:
The boat is 192 feet from the cliff.
Explanation:
Hi there!
Please see the attached figure for a graphical description of the problem.
Notice that the line of sight, the distance to the cliff and the height to the top of the lighthouse form a right triangle. Hence, we can apply trigonometric rules to find the distance from the boat to the cliff:
cos 20° = adjacent side / hypotenuse
sin 20° = opposite side / hypotenuse
The length of the opposite side is the height of the cliff plus the height of the lighthouse:
opposite side = 45 feet + 25 feet = 70 feet.
Using the equation of sin 20°, we can obtain the hypotneuse:
sin 20° = opposite side / hypotenuse
hypotenuse · sin 20° = opposite side
hypotenuse = opposite side / sin 20°
hypotenuse = 70 feet / sin 20°
hypotenuse = 205 feet
Now, using the equation of cos 20°, we can calculate the distance to the cliff (the length of the adjacent side):
cos 20° = adjacent side / hypotenuse
hypotenuse · cos 20° = adjacent side
205 feet · cos 20° = adjacent side
adjacent side = 192 feet (without rounding intermediate results)
The boat is 192 feet from the cliff.
Answer:
192 ft.
Explanation:
Tan (20) = Opp/Adj
Tan (20) = (45+25)/x
Tan (20) = 70/x
then x=70/Tan (20)
x= 192.3234 ft, and then rounded to the nearest foot...
x= 192 ft
