a 5 kg mass attached to a horizontal spring is pulled from its equilibrium position by 5 m and let go. if the spring constant is 7 n/m, what is the maximum velocity of the mass?

Answer:

Q1: 3.2km

Q2: 4.8K

Explanation:

Q1:

So db is the distance of bird, and dr is the distance of runner

db = 2vr  and the distance of bird is going to be 2 times greater than the runner.

formulas: db = 2vr & db = 2dr

Insert it in x = \(\frac{2}{3}\)L

\(\frac{2}{3}\)(2.4km) = 1.6km

Now we use formula db = 2dr

Q2:

Formulas: Vr = L /Δt & Vb = db/Δt

(Km cancel each other)

(hr cancel each other)

Answer:

6

Explanation:

From the given question, since a total of 12 V was obtained from the battery which is made up of a number of cells with each producing 2.0 V.

Assuming that the cells have a very low internal resistance, then;

minimum number of electric cells in the car battery = \(\frac{total voltage from the cells}{individual voltage of the cells}\)

                                          = \(\frac{12}{2}\)

                                          = 6

Thus, the minimum number of electric cells in the car battery is 6.

This implies that the addition of 6 cells which has 2.0 V supply in the battery produces a total of 12 V. Provided that the cells have a very low internal resistance.

Answer:

To solve this problem, you can use the following formula:

v = sqrt(k / m) * A

In this formula, v is the velocity of the mass, k is the spring constant, m is the mass of the object, and A is the amplitude of the oscillation.

Since you know the velocity of the mass at 0.25 seconds, you can substitute this value into the formula and solve for A:

2.3 m/s = sqrt(200 N/m / 3.00 kg) * A

A = 2.3 m/s / sqrt(200 N/m / 3.00 kg)

= 0.23 m

So, the amplitude of the oscillation is approximately 0.23 meters.

To find the maximum velocity of the mass, you can substitute the values for k, m, and A into the formula for velocity:

v = sqrt(200 N/m / 3.00 kg) * 0.23 m

= 2.75 m/s

So, the maximum velocity of the mass is approximately 2.75 m/s.

When rays of light actually intersect, they form a real image. A real image is an image that can be projected onto a screen because it is formed by the actual intersection of light rays.

The real image is always inverted and smaller in size than the object being imaged. The distance between the real image and the lens or mirror that forms it is dependent on the distance between the object and the lens or mirror. Real images are formed by concave mirrors and convex lenses when the object is placed beyond the focal point, as well as by convex mirrors and concave lenses when the object is placed within the focal point.

Real images are used in many applications such as in microscopes, telescopes, and cameras. In these devices, the real image is projected onto a surface such as film or an electronic sensor, which captures the image and converts it into an electrical signal.

Answer:

   q = 224 mm,   h ’= - 98 mm, real imagen

Explanation:

For this exercise let's use the constructor equation

        \(\frac{1}{f} = \frac{1}{p} + \frac{1}{q}\)

where f is the focal length, p and q are the distance to the object and the image respectively.

In a mirror the focal length is

        f = R / 2

indicate us radius of curvature is equal to the diameter of the eye

       R = 3,50  10² mm

       f = 3.50 10² /2 = 1.75 10² mm

they also say that the distance to the object is p = 0.800 10³ mm

        1 / q = 1 / f - 1 / p

        1 / q = 1 / 175 - 1 /800

        1 / q = 0.004464

         q = 224 mm

to calculate the size let's use the magnification ratio

          m = \(\frac{h'}{h} = - \frac{q}{p}\)

          h '= \(- \frac{q}{p} \ h\)

          h ’= - 224 350 / 800

          h ’= - 98 mm

in concave mirrors the image is real.

Electric current is the flow of electric charge through a conductor. This flow of charge can occur in different ways, resulting in different types of current. In direct current (DC), the electrons move at an even rate and flow only in one direction. In other words, the flow of charge is unidirectional, from the negative terminal to the positive terminal of a source of electricity, such as a battery or a generator.

In a DC circuit, the direction of the current remains the same over time, unlike in alternating current (AC) circuits, where the direction of the current changes periodically. DC is commonly used in electronic devices and equipment that require a constant and reliable flow of electrical energy. For example, batteries, electronic circuits, and some motors use DC.

DC is also used in certain applications where the flow of current needs to be controlled in one direction only. For example, in electroplating, where a metal is deposited onto a surface by an electric current, DC is used to ensure that the metal ions move in one direction only and are deposited uniformly on the surface.

In summary, DC is a type of electric current in which the flow of electrons is unidirectional, moving from the negative to the positive terminal of a source of electricity. It is commonly used in electronic devices and equipment that require a constant and reliable flow of electrical energy.

The elastic potential energy stored in the pole of a pole vaulter is an important type of potential energy involved in pole-vaulting, but it is not the only one. There is also gravitational potential energy.

When a pole vaulter runs towards the pit, they have kinetic energy. As they plant the pole into the ground and start to bend it, this kinetic energy gets converted into elastic potential energy, which is stored in the pole. When the pole begins to straighten, the stored elastic potential energy is released and converted back into kinetic energy, propelling the vaulter upwards. At the peak of the vaulter's jump, their kinetic energy is momentarily zero, and their potential energy is at its maximum. This is gravitational potential energy, which depends on their height above the ground and their mass. As the vaulter descends, the gravitational potential energy is converted back into kinetic energy until they land on the mat. So, both elastic potential energy (stored in the pole) and gravitational potential energy (related to the vaulter's height) are involved in pole-vaulting.

Answer:

a. 26.7 cm. b. 11.4 cm.

Explanation:

a. We know h'/h = d'/d where h' = image height = + 2 cm (since it is a real image), h = object height = + 1.5 cm, d' = image distance from mirror and d = object distance from mirror = 20 cm

So, from h'/h = d'/d

d = h'd/h

= 2 cm × 20 cm/1.5 cm

= 40/1.5 cm

=  26.67 cm

≅ 26.7 cm

The position of the image is 26.7 cm from the mirror

b. Using the mirror formula

1/d + 1/d' = 1/f where d = object distance from mirror = + 20 cm, d' = image distance from mirror = + 26.7 cm (its positive since its a real image) and f = focal length of mirror.

So, 1/d + 1/d' = 1/f

⇒ f = dd'/(d + d')

= 20 cm × 26.7 cm/(20 cm + 26.7 cm)

= 534/46.7

= 11.43 cm

Explanation:

Hydrostatic pressure is the pressure exerted by a fluid at equilibrium at any point of time due to the force of gravity. Hydrostatic pressure is proportional to the depth measured from the surface as the weight of the fluid increases when a downward force is applied. The hydrostatic pressure at any point in a fluid can be calculated by using the formula:

P = P0 + ρgh

where P is the hydrostatic pressure, P0 is the atmospheric pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the depth of the point from the surface.

a) In which fluid is pressure of 610 kPa first achieved?

It can be found out by adding up the hydrostatic pressures of each layer of fluid until we reach 610 kPa. Starting from gas layer:

Pgas = 60 kPa + (1 kg/m3)(9.81 m/s2)(1 m) = 60.00981 kPa

Palcohol = Pgas + (780 kg/m3)(9.81 m/s2)(60 m) = 460.00981 kPa

Poil = Palcohol + (840 kg/m3)(9.81 m/s2)(10 m) = 542.40981 kPa

Pwater = Poil + (990 kg/m3)(9.81 m/s2)(2 m) = 561.60981 kPa

Pglycerine = Pwater + (1236 kg/m3)(9.81 m/s2)(3 m) = 605.46981 kPa

Pmolasses = Pglycerine + (1500 kg/m3)(9.81 m/s2)(10 m) = 752.96981 kPa

The pressure of 610 kPa is first achieved in glycerine layer.

b) If the bottom of the pipe is at zero elevation what is

b) If the bottom of the pipe is at zero elevation what isthe pressure at bottom in kpa?

The bottom of pipe corresponds to molasses layer so use it to calculate hydrostatic pressure as calculated above:

Pbottom = Pmolasses = 752.96981 kPa

c) At what elevation is pressure of 640kpa?

It can be found out by subtracting hydrostatic pressures from each layer until it reach below 640kpa and then use interpolation to find exact elevation.

Starting from molasses layer:

Pmolasses - Pglycerine= (752.96981 - 605.46981)kpa=147.5kpa

This means that somewhere between glycerine and molasses layers there is a point with pressure of 640kpa.

Let x be distance from top surface of molasses layer to this point then:

640kpa=605.4698+1500(9.8)x

x=0.023m

Therefore elevation from bottom surface of pipe to this point is:

10-0-0-023=9-977m

d) If an open manometer attached to side pipe anywhere on oily portion determine height liquid level manometer.

An open manometer measures difference between atmospheric pressure and fluid pressure inside pipe.

Let y be height liquid level manometer above oil level then:

Patm-Poil=yρg

y=(Poil-Patm)/ρg

y=(542-4098-101325)/(1000*9-8)

y=-44-6m

This means that liquid level manometer will be below oil level by -44-6m or oil level will be above liquid level manometer by +44-6m.

The kinetic energy of the car is four times greater at the bottom than it is at the top. At the base of the hill, the car's kinetic energy is 1800 joules.

The momentum an object has as a result of motion is known as kinetic energy. We must exert force on an object if we desire to accelerate it. To apply a force, we must exert effort. Once the work is finished, the objects will be moving because energy has now been transferred to it.

Describe that a travelling internal force and speed are major factors that impact the amount of kinetic energy it will possess. Partially particles can result in the loss of kinetic energy through frictional, sound, and heat.

k = 1 /2 mv²

K = 1 /2 (100 kg) (3 m/s)²

= 450 J

K = 1 /2 (100 kg) (6 m/s)²

Explanation:

While it is true that a version of the second law of thermodynamics stated with respect to entropy states that the entropy of  a system only increases or remains the same. It never decreases!

It then appears to be a contradiction when the freezing of ice leads to a more ordered structure and a seeming decrease in entropy of the ice as water changes from liquid to solid.

This law of thermodynamics is not violated here because the entropy of the universe increases (freezing is an exothermic process). This outweighs the decrease in entropy of the system hence the change in entropy is positive and the second law of thermodynamics is not violated.
