Answer:
c 18
Step-by-step explanation:
12+12-(12/2)=18
For this case, the gravitational force is given by:
F = m * g
Where,
m: mass of the object
g: acceleration due to gravity
Substituting values we have:
F = (100) * (9.8)
F = 980 N
Answer:
The gravitational force that is pulling the object to the center of the Earth is:
F = 980 N
Answer:

Step-by-step explanation:
We are given that K is the midpoint of JL. Using this information, we want to find JL.
By the definition of midpoint, this means that:

Substitute them for their equations:

Solve for <em>x.</em> Subtract 8<em>x</em> from both sides:

Add 1 to both sides:

And divide both sides by 6. Hence:

JL is the sum of JK and KL. Hence:

Since JK = KL, substitute either one for the other:

Substitute JK for its equation:

Since we know that <em>x</em> = 2:

Thus:

His speed is 8 miles an hour. 2/3 x 12/1 = 24/3 = 8
