If the distance between two objects decreased, what would happen to the force of gravity between them?
evablogger [386]

Answer: A- It would increase

Explanation:

According to the law of universal gravitation:

F=G\frac{m_{1}m_{2}}{r^2}  

Where:  

F is the module of the attraction force exerted between both objects

G is the universal gravitation constant.  

m_{1} and m_{2} are the masses of both objects  

r is the distance between both objects

As we can see, the gravity force is directly proportional to the mass of the bodies or objects and inversely proportional to the square of the distance that separates them.

In other words:

<h2>If we decrease the distance between both objects, the gravitational force between them will increase.  </h2>

A ray of light travels across a liquid-to-glass interface. if the indices of refraction for the liquid and glass are, respective
prisoha [69]
When it comes to optics, Snell's law is the basic formula to be used. If you notice, when light hits the water, the light does not travel in the same direction. After, it hits the water, it changes in angle. Light becomes refracted. This is observed when your hands tend to become bigger if you place it underwater. The formula for Snell's Law is

n₁ sin θ₁ = n₂sin θ₂, where n is the index of refraction. This depends on the type of medium. For example, for air, n=1. The parameters θ₁ is the angle of incidence, and θ₂ is the angle of refraction. Critical angle is the incident angle needed so that the refract angle is 90°. So, modifying the equation:

n₁ sin θcrit = n₂sin 90°, since sin 90°=1,
sin θcrit = n₂/n₁
θcrit = sin ⁻¹ (n₂/n₁)

Since liquid comes first before glass, n₁=1.75 and n₂=1.52. Substituting,
θcrit = sin ⁻¹ (1.52/1.75)
θcrit = 60.29°

Ciara is swinging a 0.015 kg ball tied to a string around her head in a flat, horizontal circle. The radius of the circle is 0.5
Marat540 [252]

Answer:

Option C

Explanation:

From the question we are told that:

Mass m=0.015kg

Radius r=0.5m

Time t=0.70

Generally the equation for Tension is mathematically given by

 T=\frac{4mr}{t^2} \pi

 T=\frac{4*0.015*0.5}{(0.70)^2} (3.142)

 T=0.60N

Therefore

T=0.60 N, toward the center of the circle
