Answer:
The energy used for the 30-day period is 4878000 kilojoules.
Explanation:
According to the power bill, 1355 kilowatt-hours was used over a 30-day period. A kilowatt-hour is equal to 3600 kilojoules. Then, we calculate the energy used, measured in kilojoules, is determined by simple rule of three:
The energy used for the 30-day period is 4878000 kilojoules.
Hello! To find mass, you have to do force/acceleration. In this case, we would do 1500/35. When you do that, you would get a bunch of numbers on a calculator, but it would be 42.86 when rounded to the nearest hundredth. The mass of the object is 42.86.
Answer:
F = 172 N
Explanation:
Newton's second law of motion gives the amount of force acting on an object. Mathematically, it is given by :
F=ma
Put m =86 kg and a = 2 m/s²
So,
Hence, the net force is 172 N.
Answer:
Explanation:
Near the earth's surface where gravity is approximately 10 m/s² downward
v = u + at
v = 5 + (-10)(1) = -5 m/s
so it has the same speed but in the opposite (downward) direction.
Answer:
700 N
Explanation:
force divides in both the hand's
