What is your rate in miles/hour if you tun at a speed of 2.2 miles in 20 minutes

Answers

Answer 1
Answer: you need to convert minutes to hours so 
(2.2 mi)/(20 min) x  (60 min)/(1 hr) =  (6.6 mi)/(1 hr)

The strength of the force of gravity depends ona. the masses of the objects and their speeds.
b. the masses of the objects and the distance between them.
c. the weight of the objects and their speeds.
d. the masses of the objects and their weights.

Answers

The correct answer to the question is : B) The masses of the objects and the distance between them.

EXPLANATION :

Before going to answer this question, first we have to understand Newton's law of gravitation.

As per Newton's law of gravitation, everybody in the universe attracts every other body with a force called gravitational force or force of gravity which is directly proportional to the product of masses of the two bodies, and inversely proportional to the square of separation distance between them.

Let us consider two bodies of masses M and M' which are separated by a distance R.

The gravitational force acting between them is calculated as -

                           Gravitational force F=\ G(MM')/(R^2)

Here, G is known as universal gravitational force constant.          

From above, we see that force of gravity depends on the masses of the objects and the distance between them.

The strength of the forces of gravity between two objects is completely
determined by their masses and the distance between them.

Their speeds have no effect on the gravitational force, and their weight
IS the gravitational force.

How many Btu per hour are lost through a 100-square foot wall that is made up of a 12-inch thick concrete block wall with an R value of 1.89 and 4 inches of fiberglass insulation with an R value of 14.8? The inside temperature is 65 degrees F and the outside temperature is 15 degrees F.

Answers

Answer:

300 Btu per hour

Explanation:

given data

area = 100-square foot

thick = 12 inch

R value at 12 = 1.89

R value at 4 = 14.8

inside temperature = 65 degrees F

outside temperature = 15 degrees F

to find out

How many Btu per hour

solution

we get here How many Btu per hour that is express as

Btu per hour = (area*temp\ difference)/(r\ value\ 12 + r\ value\ 4)   ............1

put here value we get

Btu per hour = (100(65-15))/(1.89+14.8)

Btu per hour = 299.580

so Btu per hour is 300 Btu per hour
