Answer:

 a = 40.937 m / s²

Explanation:

For this exercise let's use the relationship between momentum and momentum variation

          I  = Δp

          F t = m v_f - mv₀

          F = m (v_f -v₀) / t

let's reduce the magnitudes to the SI system

          v_f = 47 km / h (1000m / 1 km) (1h / 3600 s) = 13.056 m / s

          v₀ = - 65 km / h = -18.056 m / s

the negative sign is bearing the speed is west

let's calculate

          F = m (13.056 + 18.056) / 0.76

          F = m 40.937

now we can use Newton's second law

          F = m a

          m 40.937 = m a

          a = 40.937 m / s²

Explanation:

it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f. Waves of different wavelengths.

Answer:

It is measured in the direction of the wave. Description: Wavelength is the distance from one crest to another, or from one trough to another, of a wave (which may be an electromagnetic wave, a sound wave, or any other wave).

Answer:

Both ice and snow have a lower coefficient of friction in comparison with grass, wood or pavement.

Explanation:

The main reason why people and bears, slip and fall on ice/snow is that both ice and snow have a lower coefficient of friction in comparison with grass, wood or pavement. We present below a comparative chart of coefficients of friction associated with different materials:

Material       Coefficient of Friction - Static                  

Ice/Snow                   0.05 - 0.3

Wood                          0.2 - 0.6

Asphalt                        0.5 - 0.7

Grass                            0.3 - 0.5

Explanation:

Answer:

It takes 1.14 s to move the box 4.20 m.

Explanation:

Using Newton's second law we have:

[tex]Fcos(35)-F_{f}=ma[/tex]

[tex]Fcos(35)-\mu mg=ma[/tex]

F is the force exerted and m the mass of the books

[tex]Fcos(35)-\mu mg=ma[/tex]

[tex]477cos(35)-(0.58*315)=\frac{315}{9.81}a[/tex]

So, the books accelerate at:

[tex]a=6.48\: m/s^{2}[/tex]

We know that the initial velocity is zero, so using the kinematic position equation, we have:

[tex]x=\frac{1}{2}at^{2}[/tex]

So, we just need to solve the equation for t.

[tex]4.2=\frac{1}{2}6.48t^{2}[/tex]

[tex]t=\sqrt{\frac{2*4.2}{6.48}}[/tex]

Taking the positive value of t:

[tex]t=1.14\: s[/tex]

Therefore, it takes 1.14 s to move the box 4.20 m.

I hope it helps you!

Answer:

v = 3.57 m / s

Explanation:

Let's use Newton's second law in the upper part of the circle, with the minimum speed so that the water does not rest on the circle, that is, the normal is zero

          W = m a

acceleration is centripetal

          a = v² / r

let's substitute

         mg = m v² / r

         v = [tex]\sqrt{r g }[/tex]

let's calculate

        v = [tex]\sqrt{1.3 \ 9.8}[/tex]ra 1.3 9.8

        v = 3.57 m / s

The correct answer is (b) [tex]5.17*10^{5}m[/tex]

Let us consider an object of mass m on the planet Q.

On planet Q, let the acceleration due to gravity be g = 2.24 m/[tex]s^{2}[/tex]

Mass of the planet is M = [tex]8.96*10^{21} kg[/tex]

Let its radius be R

and the universal gravitational constant G = [tex]6.67*10^{-11} m/kg[/tex]

Gravitational Force acting on the object:

[tex]mg=\frac{GMm}{R^{2} }[/tex]

[tex]R=\sqrt{\frac{GM}{g} } \\R=\sqrt{\frac{6.67*10^{-11}*8.96*10^{21} }{2.24} }\\R=5.17*10^{5} m[/tex] is the radius of the planet Q.

Answer:

18000 J

Explanation:

From the question given above, the following data were obtained:

At point 4:

Mass of cart = 600 Kg

Velocity of cart (v) = 7.745 m/s

Kinetic energy (KE) =?

KE = ½mv²

KE = ½ × 600 × 7.745²

KE = 300 × 7.745²

KE ≈ 18000 J

Therefore, the mechanical energy of the cart at point 4 is 18000 J

JUST A MINUTE KAPENG MAINIT

Answer and Explanation:

A horseshoe-shaped magnet, that is, a "U" shape, has stronger attraction and repulsion capacities than that presented by a bar-shaped magnet. This is because the lines of the magnetic field on the "U" magnet are more dense and therefore promote a stronger magnetic field. This strong magnetic field exists because in a "U" shaped magnet, the magnetic poles are on the same plane, allowing a better fluctuation of the lines of the magnetic field.

Answer:

The comet is locked in the Sun's gravity. as it falls deeper in the gravity we'll, its velocity increases. As is travels closer to the Sun, it is trying to break away, but cannot. This transforms into a sideways movement that produces a tight turn. It races further out of the gravity well, and sheds velocity.

Answer:

14, 85 J

Explanation:

The formula of potential Energy (P.E.) is

P.E. = m * g * h, where m is the mass in kilograms, g is the acceleration due to gravity (about 10 m / [tex]s^{2}[/tex] at the surface of the earth) and h is the height in meters.

Here P.E. is 0,55 kg * 10 m/s * 2,7 m = 14, 85 J

Answer:

Acceleration is directly proportional to the net force

Explanation:

The net force acting on an object is given by :

F = ma

Where

m is mass

and

a is acceleration

It can be seen that the relation between the net force and the acceleration is direct i.e. as the acceleration increases, the net force will increase. Hence, the correct option is (d).

Answer: objects A and B have the same speed.

Explanation:

Speed = distance divided by time.

Object A: 65 miles in 13 minutes

Speed (A) = 65 miles divided by 13 minutes

Speed (A) = 5 miles per minute

Object B: 125 miles in 25 minutes

Speed (B) = 125 miles divided by 25 minutes

Speed (B) = 5 miles per minute

Thus, objects A and B have the same speed.

Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.

Answer:

Average speed=1.5 m/s

Frequency of pendulum=93.75Hz

Explanation:

We are given

Frequency, [tex]f=0.100Hz[/tex]

Average wavelength =[tex]\lambda=15m[/tex]

Speed of pendulum, [tex]v=30m/s[/tex]

Wavelength, [tex]\lambda'=0.32m[/tex]

We have to find the average speed and frequency of pendulum.

We know that

Speed,[tex]v=\lambda f[/tex]

Using the formula

Average speed,[tex]v=15\times 0.1=1.5m/s[/tex]

Hence, the average speed =1.5m/s

Frequency, [tex]f=\frac{v}{\lambda'}[/tex]

Using the formula

[tex]f=\frac{30}{0.32}[/tex]

[tex]f=93.75Hz[/tex]

Hence, the frequency of a pendulum=93.75Hz
