This graph shows a proportional relationship between the number of hours (h) a business operates and the total cost (c) of electricity. Select True or False for each statement about the graph. # Question True False 1 Point A represents the total cost of electricity when operating the business for 6 hours. 2 The total cost of electricity is $8 when operating the business for 80 hours. 3 The total cost of electricity is $10 when operating the business for 1 hour.

Kinetic energy of the object = 1250 Joule.

Step-by-step explanation:

Since Kinetic energy K of an object varies with the mass m and velocity v then the relation will be defined as k is directly proportional to m×v²

Therefore K = a×m×v² defines the relation

where a is a constant.

Now an object is having m = 50 kg

v = 20 meters/second

K = 10000 joules

Then from the K = a × m × v²

10000 = a×50×(20)²

a = 10000/(50×400) = 10000/20000 = 1/2

Now we know actual relation is K = (1/2)mv²

If an object is having m = 25kg

v = 10 meters/sec

Then K = (1/2)×25×(10)² = 2500/2 = 1250 joule

Therefore kinetic energy of this object will be 1250 joule.
