Answer:

I will show u

Explanation:

F=mg

F=GMm÷r(square)

Therefore mg=GMm÷r(square)

S all m on both sides will be cut.

Therefore mass of a free falling body is useless.

Compare the energy consumption of two commonly used items in the household. Calculate the energy used by a 1.40 kW toaster oven,
Nikolay [14]

Explanation:

It is given that,

Power consumed by toaster oven, P=1.4\ kW

Time taken, t = 6 minutes = 0.1 hour

Energy used by toaster, W_{toaster}=P\times t

W_{toaster}=1.4\ kW\times 0.1\ h=0.14\ kWh

Similarly,

Power consumed by toaster oven, P=11\ W

Time taken, t = 9 minutes = 0.15 hour

Energy used by toaster, W_{toaster}=P\times t

W_{toaster}=11\ W\times 0.15\ h=1.65\ Wh=0.0016\ kWh

Hence, this is the required solution.

A student pushes on a 8-kg box with a force of 35 N forward. The force of sliding friction is 10 N backward. What is the acceler
Ne4ueva [31]

Answer:

(35 N - 10 N)/8kg = 3.125 m/s^2

Explanation:

The formula for Force is:

Force = Mass*Acceleration

(Force is equal to Mass times Acceleration)

Since we're told to find the acceleration of the box. We make acceleration the subject of the equation:

Acceleration = Force/Mass

(Acceleration equal to Force divided by Mass)

We know that the force are 35 N forward and 10 N backward, and the weight of the box is 8kg.

= (35 N - 10 N)/8kg

The reason that 35 N minus 10 N is because the 10 N is pushing the box backward.

= 25 N/8kg

= 3.125 m/s^2

Hope it helps :DD
