the 0.5???????? collar c starts from rest at ???? and slides with negligible friction on the fixed rod in the vertical plane. determine the velocity ???? with which the collar strikes end ???? when acted upon by the 5 ???? force, which is constant in direction. neglect the small dimensions of the collar.

Answers

Answer 1

The velocity with which the collar strikes end B is 2.32 m/s.

How to calculate the work done by external forces on a body?
We conclude from the work energy theorem that any work performed on a body results in a change in total energy.

Given, mass of the collar = m = 0.5 kg
Therefore, effective weight of the collar = m*g = (0.5)*(9.81) = 4.905 N
Force acting on the collar = 5 N
We know, work done by external forces equates to the change in kinetic energy of the body.
Thus, ΔU = T ⇒ 0.5 * 0.5 * (v²-0) = 0.2[5 cos(30°) - 5 sin(30°) + 4.905)
⇒ v² = 5.39 m²/s² ⇒ v = 2.32 m/s.
Therefore, the velocity with which the collar strikes end B when acted upon by the 5N force is 2.32 m/s.

starting from rest, an iron block with mass mb slides down a frictionless hill of height h. at the base of the hill, it collides with and sticks to a magnet with mass mm.

Answers

The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction. There are various kinds of friction: Two solid surfaces in touch are opposed to one another's relative lateral motion by dry friction.

"V = √2gH*{mb/(mM+mM)}"

Given

First block's mass is mB.

Second block's mass is mM.

H = Height

The mass's speed right before impact is m.

V = √2gH

Since there is no external force acting on the masses, the linear momentum will remain constant.

Initially linear momentum equals ultimately linear momentum

Pi = mB V

Let's assume that the system's final speed is v.

Pf = (mM + mB)

V = (mM + mB)

There are four different challenges in the example given. The first one refers to the initial ball's mass. This is assumed assuming that each person is equivalent to 1.5 telegrams and the second pool ball's mass. M2 is that This also equates to an initial speed of 2.3 kg.

The first pool ball is moving at 25 meters per second, whereas the second pool ball was initially at rest. The first ball ultimately comes to rest after colliding with the second pool ball, becoming zero, and we must determine the second ball's final speed. To do this, we will apply the principle of conservation of linear momentum, which states that the linear momentum of both balls remains constant.

The balls before to impact indicate M 1. We have a total of two from one plus M. That corresponds to the ultimate momentum and one we F plus M. This is 1.5 kg in 2 25 m per second plus zero, and we need to plug in all the known variables.

explain and justify what would happen to the work done by the cable and magnitude of tension force as the crate was lifted the same height h but with a longer ramp.

Answers

Friction comes in two flavors: kinetic and static. Static friction affects a system or an object at rest, whereas kinetic friction affects an object in motion.

Typically, the maximal static friction between the objects is greater than the kinetic friction. Consider attempting to move a large crate across a concrete floor. The crate might not budge no matter how much you push on it. In other words, the static friction reacts to your actions by increasing to match and move in the opposite direction of your push.

However, if you exert enough force, the crate eventually looks to slip and begin to move. The kinetic friction force is lower than the static friction force, making it simpler to maintain motion once it is underway.

You would have to push more harder to initiate and maintain motion if you added mass to the crate (by, say, stacking a box on top of it). On the other hand, if you greased the concrete, it would be simpler to start and maintain the box.

a roller coaster starts at rest at the top of a 51-meter-high frictionless track. at the bottom of the track, what is the approximate speed of the roller coaster?

Answers

The approximate speed of the roller coaster is 32m/s.  

Considering that the earth and the roller coaster are both parts of one system.

We can use the law of conservation of energy,

This law states that in a system, the sum of total energy is always conserved.

So we can say that the energy at the top of roller coaster will be equal to the energy at the bottom of the roller coaster.

At top, whole energy is potential energy and the bottom whole energy is kinetic energy,

So we can write,

PE = KE

Mgh = 1/2Mv²

Where M is mass of roller coaster,

v is the speed of roller coaster,

g is acceleration due to gravity and,

h is the height of the roller coaster,

Putting all the values,

gh = 1/2v²

v² = 2gh

v² = 2×9.8×51

v² = 999.6

v = 31.61 m/s.

The simplest type of capacitor is the parallel plate capacitor. The capacitance value in Farads is fixed by the surface area of the conductive plates and the space between them, and it can be built using two metal or metallized foil plates placed parallel to one another at a distance.

Chloroprene is polymerized to create the family of synthetic rubbers known as neoprene. Good chemical stability and flexibility are displayed by neoprene over a broad temperature range.

A parallel-plate capacitor's capacitance is calculated by multiplying the dielectric constant by the permittivity of free space, the area of the plates, and the distance between them.

The generalised formula for a parallel plate capacitor's capacitance is given as C = ε(A/d), where stands for the absolute permittivity of the material being utilised as the dielectric. The value of the dielectric constant, commonly referred to as the "permittivity of open space," is 8.854 x 10-12 Farads per metre.

Therefore, Capacitance = ε x (area of plates / thickness of rubber)

Using this information as well as the formula above, we can calculate the specific heat capacity of the substance:

c = [tex]\frac{5200\ \mathrm{J}}{2\ \mathrm{kg} \times 5^{\circ}\mathrm{C}}[/tex]

  = 5 J/kg °C

Therefore the specific heat capacity of the substance is 5 J/kg °C.

Answer: 520 J

Explanation:

find the difference between the moon’s gravitational force on a 1 kg mass on the side of the earth facing the moon and an identical mass on the side of the earth opposite the moon (this difference is called the tidal force).

Answers

The tidal force is a gravitational phenomenon that, as a result of a gradient in the gravitational field from the other body, stretches a body along a line towards the center of mass of another body.

The surface gravity of the Moon is around 1/6th as strong, or 1.6 meters per second every second. Because the Moon is significantly less massive than Earth, its surface gravity is weaker. The surface gravity of a body is inversely related to the square of its radius but directly proportional to its mass.

The Earth is forced to orbit around the Earth-Moon center of mass, which is situated roughly 1600 km beneath the surface of the planet along a line connecting it to the Moon. It is possible to think of the tidal force as the difference between the force at the Earth's center and all other locations.

At sea level, where we can see the ocean tides, this distinction is evident. (Remember that the tidal forces' impact on sea level is measured relative to the baseline sea level.

As we previously observed, the rotation of the Earth causes a significant bulge along its equator. Here, we merely take into account the much smaller tidal bulge measured from that baseline sea level, which establishes the baseline sea level.)

_______ is essential for building amino acids.

(Choose One)


Nitrogen


Oxygen


Calcium


Carbon


Hydrogen


Phosphorus

Answers

Answer:

Oxygen or Hydrogen?

Explanation:

To make amino acids, fermentation tanks are filled with molasses and sugar ingredients such as sugar cane, corn and cassava. Ideal conditions are achieved for stirring, oxygen supply, temperature and pH levels. The desired amino acids are then purified from this fermented broth.

"An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid."

Hope this helps

Which would conduct the least amount of electricity?

a
A copper wire
b
A piece of wood
c
An iron rod
d
A tin can

Answers

Answer:

The one that conducts the least amount of electricity is a piece of wood.

Explanation:

We are given four options of which three are metals and one is not, and we have to decide which one would conduct the least amount of electricity or, in other words, which one is the better insulator.

Metals, because of their molecular properties, are the best electricity and heat solid conductors. This means they do not resist  too to the flow of current. Therefore, they conduct high amounts of electricity.

Materials such as wood, plastic, or rubber are known as insulators because they have a higher resistance to the flow of electric current. In other words, they conduct very small amounts of electricity.

Hence, of these options, the one that conducts the least amount of electricity is a piece of wood.

(Hi fyi this answer took a lot of time & effort to make sure it was accurate, precise and to the point to be produced, so if you could opt this answer as the brainliest it would mean the world to me,)

To measure the capacitance C of a capacitor, you attach the capacitor to a battery and wait until it is fully charged. You then disconnect the capacitor from the battery and let it discharge through a resistor of resistance R. You measure the time T1/2 that it takes the voltage across the resistor to decrease to half its initial value at the instant that the connection to the capacitor is first completed. You repeat this for several different resistors. You plot the data as T1/2 versus R and find that they lie close to a straight line that has slope 7.50 F.What is the capacitance C of the capacitor? help me please!!!!!!!!!!!
