Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1=14.25 kg is on a horizontal table and the other block with mass m2=7.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Find the magnitude of the tension in the rope, T, in newtons.

Answers

The magnitude of the tension in the rope of this two-block system is:

[tex]T=73.56\: N[/tex]

We have here an equilibrium system, which means that all forces acting are equal to zero.

We can analyze the hanging block. We just two forces acting in this block, the tension upwards (T) direction and the weight downward (W) direction.

[tex]T-W_{2}=0[/tex]

[tex]T=W_{2}[/tex]

[tex]T=m_{2}g[/tex]

The mass of the second mass is 7.5 kg and g = 9.81 m/s².

[tex]T=7.5*9.81[/tex]

[tex]T=73.56\: N[/tex]

Therefore, the tension will be 73.56 N.

What is velocity ?

The directional speed of an item in motion, as measured by a specific unit of time and viewed from a certain point of reference, is what is referred to as velocity.

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route. In other words, velocity is a vector, whereas speed is a scalar number.

Velocity is a unit of measurement for motion that begins in one location and moves to another. There are several practical uses for velocity, but one of the more frequent ones is figuring out how quickly you or anything in motion will go from one place to another.

Answers

Answer: “Chemical equations need to be balanced in order to satisfy the law of conservation of matter, which states that in a closed system matter is neither created nor destroyed. There are some things called mole ratios, which are important because mole ratios allow you change moles of a substance to moles of another substance. The mole ratio is the magic that changes from A to B. The mole ratios come from the chemical formula or equation.”

You need to make sure you have an equal balance so that you don’t make a mistake and mess up the reaction. If anything goes minutely wrong, it may alter the substance. Knowing the ratios of substances can help to make the product as expected.

It is important to know the ratio of substances because:

Mole ratios are important because mole ratios allow you change moles of a substance to moles of another substance. The mole ratio is the magic that changes from A to B. The mole ratios come from the chemical formula or equation.The mole ratios are determined using the coefficients of the substances in the balanced chemical equation.

The Hall effect is to be used to find the sign of charge carriers in a semiconductor sample. The probe is placed between the poles of a magnet so that magnetic field is pointed up. A current is passed through a rectangular sample placed horizontally. As current is passed through the sample in the east direction, the north side of the sample is found to be at a higher potential than the south side. Make a sketch of the situation, then decide if the number density of charge carriers is positively or negatively charged.

Answers

Answer:

the sign of these carriers is POSITIVE

Explanation:

In the effect, he found the charge carriers that were subjected to two forces, one electric and the other magnetic.

F = F_e + F_m = q E + q v x B

bold indicates vectors

The electric field goes to the east, therefore the current also has this direction, the vector product of the velocity of the charge carriers towards the east and the magnetic field upwards, using the right hand rule a magnetic force is created towards the north if the carriers are positive.

In the exercise they indicate that the north side has a higher potential than the south side, therefore there must be an accumulation of carriers on this side that create an electric field (Hall) that is put to the magnetic force until reaching equilibrium when the total force is zero.

Therefore the sign of these carriers is POSITIVE

Answers

Answer: A. Work is done on the system and heat is transferred from the system for a net decrease in internal energy.

Explanation:

A refrigerator is a device which dispenses heat from the close system to a warmer area or in the surrounding. By dispensing the heat the internal temperature of the refrigerator drops. The system of refrigerator violates the second law of thermodynamics. As it performs the work to cool the region instead of heating the region. The work is done on the system and the internal energy decreases and the heat energy is liberated to the surrounding area. A refrigerator is an open system.

the track to the surroundings. How does lack of friction affect the energy of the roller coaster
System?

Answers

Answer:

No energy leaves the system if there’s no friction between the cars and the tracks.

Explanation:

The lack of friction affects the energy of the roller coaster system. Because no energy leaves the system if there is no friction between the cars and the rails.

What is the friction force?

It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N).

Gravitational potential and kinetic energy, which are the roller coaster's usable energies, are converted to heat energy by friction.

A roller coaster is affected by air friction and resistance since it is in the air, and this creates a force that opposes the movement of the cart.

A portion of the energy is lost as a result of friction caused by the brakes, wind drag on the train, and friction between the wheels and the rails.

Since there is no friction on the roller coaster track, there is no heat transmission from the track to the environment.

The roller coaster system's energy is impacted by the absence of friction. Because if there is no friction between the automobiles and the rails, no energy exits the system.

Hence, lack of friction affects the energy of the roller coaster system.

g You shine orange laser light that has a wavelength of 600 nm through a narrow slit. The slit forms a diffraction pattern on a distant screen that has been set up behind the slit. The first dark fringe in the diffraction pattern is 4.0 cm from the center point of the pattern. If you replace the orange laser with an unknown laser and observe that the second dark fringe of the diffraction pattern appear at 4.0 cm from the center point, what is the wavelength of the unknown laser

Answers

Answer:

λ = 3 10⁻⁷ m, UV laser

Explanation:

The diffraction phenomenon is described by the expression

a sin θ = m λ

let's use trigonometry

tan θ = y / L

as in this phenomenon the angles are small

tan θ = [tex]\frac{sin \ \theta}{cos \ \theta}[/tex] = sin θ

sin θ = y / L

we substitute

a y / L = m λ

let's apply this equation to the initial data

a 0.04 / L = 1 600 10⁻⁹

a / L = 1.5 10⁻⁵

now they tell us that we change the laser and we have y = 0.04 m for m = 2

a 0.04 / L = 2 λ

a / L = 50 λ

we solve the two expression is

1.5 10⁻⁵ = 50 λ

λ = 1.5 10⁻⁵ / 50

λ = 3 10⁻⁷ m

After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 48.0 cm . The explorer finds that the pendulum completes 93.0 full swing cycles in a time of 144 s . Part A What is the magnitude of the gravitational acceleration on this planet

Answers

Answer:

g = 12.22 m/s²

Explanation:

The time period of this pendulum is given as follows:

[tex]T = \frac{time\ taken}{no. of cycles}\\\\T = \frac{144\ s}{93}\\\\T = 1.55\ s[/tex]

but the formula for the time period of a simple pendulum is as follows:

[tex]T=2\pi \sqrt{\frac{l}{g}}\\[/tex]

where,

L = length of pednulum = 48 cm = 0.48 m

g = magnitude of th gravitational acceleration on this planet = ?

Therefore,

[tex]1.55\ s=2\pi \sqrt{\frac{0.48\ m}{g}}\\\\\sqrt{g} = 2\pi \sqrt{\frac{0.48\ m}{1.55\ s}}\\\\g = 3.49^{2}\\[/tex]

The take-up reel of a cassette tape has a radius of 2.5 cm. Find the length of the tape that passes around the reel in 7.1 s when the reel rotates at an average angular speed of 1.9 rad/s.

Answers

Answer:

s = 0.337 m

Explanation:

First, we will find the angular displacement of the reel:

[tex]\theta = \omega t[/tex]

where,

θ = angular displacement = ?

ω = angular speed = 1.9 rad/s

t = time taken = 7.1 s

Therefore,

θ = (1.9\ rad/s)(7.1 s)

θ = 13.5 rad

Now, we will find out the length of tape:

s = rθ

where,

s = length of tape = ?

r = radius of reel = 2.5 cm = 0.025 m

Therefore,

s = (0.025 m)(13.5 rad)

s = 0.337 m
