The property of matter that determines the direction of heat flow is the

Kobotan [32]

Answer:

Temperature

Explanation:

The heat flows from high temperature to low temperature.So we can say that temperature is the property that decide the direction of heat flow.Like in the electric system current flow high voltage to low voltage ,so we can say that voltage is the property which determine the direction of current flow.

So the answer is Temperature.

When applying a horizontal force of 30N, an object of mass 6 kg accelerates at 4m/s2. The force of friction on the surface must

Rus_ich [418]

Using Newton's Second Law, F = ma, where F is the net force

So the net force is:

F = (6kg)(4m/s^2) = 24N

Since you are applying a horizontal force of 30N, we can find the force of friction by the difference of the net force and the applied force.

30N-24N = 6N

$F_{f} = 6N$

What is the voltage of this circuit.

liberstina [14]

Answer:

110.4 v

Explanation:

Find the equivalent resistance of the two parallel circuits

R1 and R2 in parallel = R1 * R2 / (R1+ R2) = <u>1 ohm </u>

similarly R4 and R5 = <u>4.77 ohms</u>

Now you can add the three resistances into one (R3=10)

1 ohm + 10 ohm + 4.77 ohm = 15.77 ohms

Now

V = IR

V = 7 amps * 15.77 ohm = 110.4 v
