Answer:

Instead of pushing straight down, the load of an arch bridge is carried outward along the curve of the arch to the supports at each end. The weight is transferred to the supports at either end. These supports, called the abutments, carry the load and keep the ends of the bridge from spreading out.

A billiard ball (ball #1) moving at 5.00 m/s strikes a stationary ball (ball #2) of the same mass. after the collision, ball #1
Rashid [163]
If it is completely elastic, you can calculate the velocity of the second ball from the kinetic energy 
<span>v1 = velocity of #1 </span>
<span>v1' = velocity of #1 after collision </span>
<span>v2' = velocity of #2 after collision. </span>

<span>kinetic energy: v1^2 = v1' ^2 + v2' ^2 (1/2 and m cancel out) </span>
<span>5^2 = 4.35^2 + v2' ^2 </span>
<span>v2 = 2.46 m/s <--- ANSWER</span>

State and explain newton second law of motion also describe the concept of force, represent it quantiatively and derive the unit
Molodets [167]

Explanation:

Newton's second law of motion states F=ma which means force is equal to mass multiplied by acceleration which in simple terms means If you give mass force it will accelerate the concept of force in physics is any interaction that when unopposed will change the motion of an object.

Dx= 7.14m and Dy = -7.55m<br> What is the direction and magnitude of the vector
KengaRu [80]

The Magnitude of the Vector is 10.39m and the direction of the vector is - 46.7°.

<u>Explanation:</u>

GIven dx=7.14m and dy= -7.55m,

The Magnitude of the Vector=\sqrt{dy^{2} +dx^{2} }

Magnitude d= \sqrt{(7.14)^{2} +(-7.55)^{2} } .

                  d=\sqrt{50.97+57}

                  d=\sqrt{107.98}

                  d= 10.39m.

Direction Ф = tan^{-1}\frac{dy}{dx}

                      =tan^{-1} \frac{-7.55}{7.14}      

                      = tan^{-1}(-1.06)

                Ф    = - 46.7°.

Hydraulic brakes use Pascal’s principle. The driver exerts a force of 100 N on the brake pedal. This force is increased by the s
Rus_ich [418]

Answer:

Explanation:

Pascal's law states that when there is an increase in pressure at any point in a confined fluid, the pressure is equally distributed at every other point in the container.

The formulas that relate to this are given below:

P1 = P2 (since the pressures are equal throughout).

P2 is the pressure transmitted in the hydraulic system

N.B : P= Force/ Area

Therefore we have  

F1/A1 = P2

F1= the force exerted by the driver = 100N  

P2= 100/A1 N/m² or 100/A1 pa or 100/(101325× A1) atm
