Correct answer choice is:
B) Gravity
Explanation:
Gravity is a force of attraction that endures within any two bodies, any two groups, any two particles. Gravity is not just the attraction among objects and the Earth. It is because the Earth going around the Sun is in a magnetic stability. The speed of the Earth's action generates a centrifugal force which balances the gravitational force among the Sun and the Earth. Because there is no force to hold it.

b. the length of your spaceship is not changing.
c. the length of your spaceship is getting longer. 5.) A star is moving towards the earth with a speed at 90% the speed of light. It emits light, which moves away from the star at the speed of light. Relative to us on earth, what is the speed of the light moving toward us from the star?
a. 0.90c
b. 1.9c
c. 1.20c
d. 1.1c e,) c
Answer
2.65 quarts
Explanation
1 quart = 0.943 liters
To find the how many quarts are there in 2.50 litres we divide the 2.50 litres with 0.943 litres.
Number of quarts = 2.50/0.943
= 2.651113468
To the nearest hundredths the answer = 2.65 quarts
the answer would be 2.65 quarts
The Objects separated by gravitational force of 360 N, masses 6.25 × 10¹⁴ kg and 7.20 × 10⁵ kg. Applying Newton's law with G = 6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻² yields distance is 2.79139 km.
We can apply Newton's law of universal gravitation to calculate the distance between the two objects. The formula takes the form:
F = (G ⋅ m₁ ⋅ m₂) / r²
Where:
F represents the force between the two objects
G stands for the gravitational constant (6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻²)
m₁ and m₂ denote the masses of the two objects
r indicates the distance between the centers of the two objects
Given that the force F = 360 N, m₁ = 6.25 × 10¹⁴ kg, and m₂ = 7.20 × 10⁵ kg, we can solve for r:
r² = (G ⋅ m₁ ⋅ m₂) / F
r = √((G ⋅ m₁ ⋅ m₂) / F)
Now, substituting the values and solving for r:
r = √(((6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻²) ⋅ (6.25 × 10¹⁴ kg) ⋅ (7.20 × 10⁵ kg)) / 360 N)
r ≈ 2791.39 m
Finally, converting the distance from meters to kilometers:
r ≈ 2.79139 km
Consequently, the two objects are approximately 2.79139 kilometers apart.

Answer:
(a). The speed of car will increases.
(b). The speed of car will decreases.
Explanation:
Given that,
A car is traveling from your left to your right at a constant velocity.
We need to find two actions could the driver take
Using given data
(a). If the velocity and acceleration of car to the right
It means the velocity and acceleration of car is in same direction then the speed of car will increases.
(b). If the velocity to the right and the acceleration to the left
It means the velocity and acceleration of car is in opposite direction then the speed of car will decreases.
Hence, (a). The speed of car will increases.
(b). The speed of car will decreases.
Answer:
3.0
Same explanation as the person above but the significant figures must be considered in physics.
