500 N is the answer, you just tell that the moon is attracted towards the person because of the Earth's huge mass.
Answer:
Explanation:
If the distance () and speed (), measured in centimeters and centimeters per hour, respectively, are directly proportional to each other, then each set of values must observe the following relationship:
(Eq. 1)
Where is the proportionality constant, measured in .
If we know that , , , , and , then the constant of proportionality for each pair is:
As , we conclude that correct equation is .
Answer:
$6.68
Explanation:
The current running through the device would be its outlet voltage divided by the resistance:
I = U/R = 115 / 11.4 = 10.09 A
The power generated by this device is the product of its current and voltage
P = IU = 10.09 * 115 = 1160 W or 1.16 kW
If running this device for 36 hours then the total energy it would consume is
E = Pt = 1.16 * 36 = 41.76 kWh
Therefore the total cost of electrical energy is
C = Ec = 41.76*0.16 = $6.68
please give me brainlest!!
the answer is A.
