Hi,

Newton's Law of Inertia explains this action because the resistance of the seat belt allows the change in its state of motion. So because the change of speed, your body moves forward but is restricted by the seat belt.

Have a great day!

A jet airplane is in level flight. The mass of the airplane is m=8950 kg. The airplane travels at a constant speed around a circ

Answer:

The net force is 91780.8 N.

Explanation:

mass, m = 8950 kg

Radius, R = 9.33 miles = 15015.2 m

Time, T = 0.123 h = 442.8 s

There are two forces acting on the plane.

Horizontal force is the centripetal force and the vertical force is the weight.

$Fx =m R w^2\\\\Fx = m R \frac{4\pi^2}{T^2}\\\\Fx = 8950\times 15015.2\times \frac{4\times 3.14\times 3.14}{442.8\times 442.8}\\\\Fx = 27030.8 N \\\\Fy = m g \\\\ Fy = 8950\times 9.8 \\\\Fy = 87710 N$

The net force is

$F = \sqrt{Fx^2 + Fy^2}\\\\F = \sqrt {27030.8^2 + 87710^2}\\\\F = 91780.8 N$

If the thermal energy of the system increases by 400 J, and 1,100 J of heat were added to the system, how much work did the syst

Luba_88 [7]

700 J is the work done by the system.

<u>Explanation:</u>

The first law of thermodynamics is that the change in internal energy of the system is equal to the net heat transfer to the system minus the complete work performed by the system.

$\Delta \boldsymbol{U}=\boldsymbol{Q}-\boldsymbol{W}$

Where,

∆U – Change in internal energy

Q – Heat transfer to the system

Q – Work done

Here,

<u>Given data:</u>

∆U - 400 J

Q - 1100 J

We need to the work done by the system (W)

By applying the given values in the above equation, we get

400 = 1100 - W

W = 1100 - 400 = 700 J
