Answer:
Equal to the magnitude of F⃗
Explanation:
By Newton's third Law of motion, which states that:
<em>When</em><em> </em><em>two</em><em> </em><em>bodies</em><em> </em><em>interact</em><em> </em><em>they</em><em> </em><em>apply</em><em> </em><em>forces</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em> </em><em>a</em><em>m</em><em>other</em><em>,</em><em> </em><em>which</em><em> </em><em>are</em><em> </em><em>equal</em><em> </em><em>in</em><em> </em><em>magnitude</em><em> </em><em>and</em><em> </em><em>opposite</em><em> </em><em>in</em><em> </em><em>direction</em><em>.</em>
If the horse applies a force F⃗ on the cart, the cart must exert an equal and opposite force on the horse.
That is, the <u>magnitude</u> of the force applied by the horse on the cart is EQUAL to the <u>magnitude</u> of the force applied by the cart on the horse, but OPPOSITE in <u>direction</u><u>.</u>

Answer:
(a) the height in the open water column is: 18.15 (ft), (b) the gauge pressure acting on the bottom tank surface AB is: 8.73 (Psi) and (c) the absolute pressure of the air in the top of the tank with local atmospheric pressure at 14.7 Psi will be: 21.7 (Psi).
Explanation:
We need to apply the Pascal's Law, () where P is pressure, γ is the specific weight of the fluid and h is the height of the column of fluid, to find the pressure at differents points in the tank (see attached). First we need to assume a property of the water called specific weight as: 62.4 (lbf/ft^3) or 0.03612 (lbf/in^3). Then knowing that 1 feet as the same as 12 inches and appling Pascal's Law, we get: and the other hand, we have: and knowing that the pressure at point C and point D are the same, we can find the h as:, so getting h=217.75(in) or 18.15(ft) (a). Now similarly to find the gauge pressure acting on the bottom of the tank surface AB we can apply Pascal's Law as: (b). Finally we can find the absolute pressure of the air in the top of the tank, assuming a local atmospheric pressure as 14.7 (Psi) so: (c).
Answer:
An unbalanced force means that there are more than one forces with different directions or magnitudes affecting the object. In this case, the vector addition of the forces should be done. The vector addition will result a net force. The object will move in the direction of the net force.
Answer:
The kinetic energy of photoelectrons at the surface grows linearly with the increasing frequency of incident radiation. Measurements for all metal surfaces give linear plots with one slope.
