<h2>Answer: Decreasing the distance between Hox and Blox, increasing the mass of Hox, or increasing the mass of Hox and Blox. </h2>

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 planets  

G is the universal gravitation constant.  

m_{1} and m_{2} are the masses of both planets.  

r is the distance between both planets.

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

In other words:

If we decrease the distance between both planets (Hox and Blox), the gravitational pull between them will increase.  

On the other hand, if we keep the distance between Hox and Blox, but we increase the mass of one of them, or increase the mass of both, the gravitational pull between them will also increase.

In the figure below consider R = 11 Ω. Calculate the equivalent resistance.
nalin [4]

Answer:42R/41

Explanation:

R/2+R=3R/2

1/r=1/(3R/2)+1/R

1/r=2/3R+1/R

1/r=5/3R

5r=3R

r=3R/5

3R/5+3R/2=21R/10

1/r=1/2R+1/2R

1/r=1/R

r=R

R+R=2R

1/r=1/2R +1/(21R/10)

1/r=1/2R+10/21R

1/r=41/42R

41r=42R

r=42R/41

How does the momentum of a 75 kilogram stationary football player compare with that of a 70 kilogram player moving at a velocity
pashok25 [27]
Momentum of an object = (its mass) x (its speed) .

Since speed is a factor of momentum, an object that
isn't moving doesn't have any.

-- The moving player has momentum. 

-- The stationary one doesn't.

WORTH 10 POINTS! I WILL GIVE BRAINLIEST!
Sav [38]

Answer:

The Sun’s magnetic field, solar winds and the Earth's magnetic tail are responsible for making the aurora lights in the north and south poles look different, say international scientists. Researching the interactions of these phenomena have debunked previous theories around why the lights can have different shapes and can occur in different locations. This research also helps scientists to better understand the interactions between the sun and earth, which could help with predicting space weather.
