A 5 kg block is being pushed horizontally across a level surface at a constant velocity. What is the magnitude of the Normal for

ce acting on the block?

Answer:

50 N.

Explanation:

On top of a horizontal surface, the normal force acting on an object is equivalent to the force of gravity acting on the object. That is:

\displaystyle \begin{aligned} F_N = F_g & = ma \\ & = mg\end{aligned}

The mass of the block is 5 kg and the given force due to gravity is 10 N/kg. Substitute and evaluate:

\displaystyle F_N = F_g = (5\text{ kg})(10 \text{ N/kg}) = 50 \text{ N}

In conclusion, the normal force acting on the block is 50 N.

choli [55]

F = 52000 N

m = 1060 kg

a= F/m = 52000 N/1060 kg = 49.0566 m/s^2

A proton in a particle accelerator is traveling at a speed of 0.99c.(a) If you use the approximate nonrelativistic equation for
____ [38]

Answer:

a)  p = 4.96 10⁻¹⁹ kg m / s , b)  p = 35 .18 10⁻¹⁹  kg m / s ,

c)  p_correst / p_approximate = 7.09

Explanation:

a) The moment is defined in classical mechanics as

                 p = m v

Let's calculate its value

               p = 1.67 10⁻²⁷ 0.99 3. 10⁸

               p = 4.96 10⁻¹⁹ kg m / s

b) in special relativity the moment is defined as

               p = m v / √(1 –v² / c²)

Let's calculate

                p = 1.67 10⁻²⁷ 0.99 10⁸/ √(1- 0.99²)

                p = 4.96 10⁻¹⁹ / 0.141

                p = 35 .18 10⁻¹⁹  kg m / s

c) the relationship between the two values ​​is

            p_correst / p_approximate = 35.18 / 4.96

            p_correst / p_approximate = 7.09

As a wave moves through a medium, particles are displaced and (2 points)
Scorpion4ik [409]

As a wave moves through a medium, particles are displaced and return to their normal position after the wave passes.

Explanation:

A wave is a traveling disturbance that  carries energy from one location to  another. All waves move in straight lines  outward and away from the source of a  disturbance. Like the radiating circular  ripples, the waves of water carry energy  away from where a rock was dropped into  the pond.

Waves can move as a single pulse or as a continuous series of waves, carrying  energy away from its source. A pulse is a single disturbance, wave, or ripple that moves  outward from the point of disturbance. A train of waves are many waves emitted over and  over again from a single source.

As waves travel through matter, they will temporarily  displace the molecules or particles in matter up-and-down  or side-to-side. Waves move the energy but they do not  carry the matter with them longitudinally as they move  through matter. Once the disturbance passes, the medium  will return to its original state or position.

Therefore, as the waves move through a medium, particles are displaced and return to their normal position after the wave passes.
