Answer:

E to F

Explanation:

The velocity decreases during segment E to F since the slope of the curve decreases with time.

We have 5 segments in the given graph between position and time. Analyzing each segment we can conclude the following:

Segment A to B: the position remains constant as time increases, this means that the velocity is zero.

Segment B to C: the rate of increase in the position slowly becomes greater as time passes, which means velocity is increasing and the object is accelerating

Segment C to D: The rate of increase in the position is constant with respect to the rate of increase in time, the slope of the curve is constant, which means that the velocity is constant.

Segment D to E: same as the segment A to B, the velocity is zero.

Segment E to F: The rate of increase in the position slowly decreases with time, and the slope of the curve decreases with time, which means the velocity is decreasing.

Answer:

The mass of the cars and people and the height of the track where the cars are located determine the potential energy in the system. Potential energy depends on an object’s mass and height and the gravitational pull on the object. A change in gravity would result in a change in potential energy. For example, if the track were located on the Moon instead of Earth, the potential energy would be different.

Answer:

the magnet is not moving relative to the wire so B

Explanation:

The magnet is not moving relative to the wire if, A permanent magnet is placed in a coil of wire, If there is no electric current in the wire so, option B is correct.

Electric current is a term used to describe how much electricity flows across a circuit and how it flows in an electronic circuit. Amperes are used to measure it (A). The more electricity flowing across the circuit, the higher the ampere value.

When current flows through a coil of wire, it transforms into an electromagnet. The coil spins as a result of the electromagnet's interaction with a permanent magnet.

An electromagnet is created when current passes through a coil of wire. Because of the electromagnet's interaction with a permanent magnet, the coil spins.

En donde:

[tex]v_{f}[/tex]: es la velocidad final = 0 (se detiene)

[tex]v_{f}[/tex]: es la velocidad inicial

a: es la aceleración=?

Answer:

Workdone = 1250Nm

Explanation:

Given the following data;

Force, F = 500N

Distance, d = 2.5m

Workdone is given by the formula;

[tex] Workdone = force * distance[/tex]

Substituting into the equation, we have

[tex] Workdone = 500 * 2.5 [/tex]  

Workdone = 1250Nm

Therefore, the actual work done by the worker is 1250 Newton-meter.

The actual work done by the worker is 1250 J.

Work can be defined as the product of force and distance. The s.i unit of work is Joules

The formula of work is

W = Fd....................... Equation 1

Where W = work done by the worker, F = Force, d = distance.

From the question,

Given: F = 500 N, d =  2.5 m

Substitute these values into equation 1

W = 500×2.5

W = 1250 J

Hence, the actual work done by the worker is 1250 J

Given :

Reem took a wire of length 10 cm. Her friend Nain took a wire of 5 cm of the same material and thickness both of them connected with wires as shown in the circuit given in figure. The current flowing in both the circuits is the same.

To Find :

Will the heat produced in both the cases be equal.

Solution :

Heat released is given by :

H = i²Rt

Here, R is resistance and is given by :

[tex]R = \dfrac{\rho L}{A}[/tex]

So,

[tex]H = i^2\times \dfrac{\rho L}{A} t\\\\H = \dfrac{i^2\rho Lt}{A}[/tex]

Now, in the question every thing is constant except for the length of the wire and from above equation heat is directly proportional to the length of the wire.

So, heat produced by Reem's wire is more than Nain one.

Hence, this is the required solution.

The particles in the gas are farther apart from each other, therefore illustration (C) represents the arrangement of particles in a gas.

Matter exists in different forms in nature in which three common states are solid, liquid, and gaseous. Some substances have a definite shape and some can flow, and take the shape of their container like water, some forms of matter do not have certain shapes or sizes.

The particles in solids are highly closely packed so illustration (D) represents the particles in a solid state. The compact packing of solids means that the particles are very close to each other and do not show movement.

In liquids, the particles are some distance away from each other and they show some movements. The particles in a liquid have some kinetic energy.

In gases, the particles are farther from each other and thus their particles show large movement. The kinetic energy of particles in gases is the greatest in comparison to that of solids and liquids.

Answer:

7167.27N/m

Explanation:

To get the force constant k, we will use the formula;

F = kx where

F is the force acting on the object down the plane

k is the spring constant

x is the extension

The force acting down the ramp us F = Wsintheta. The formula will become;

Wsintheta = kx

mgsintheta = kx

K = mgsintheta/x

K = (800)(9.8)sin47°/0.8

K= 7840sin47°/0.8

K = 5733.81/0.8

K = 7167.27N/m

Hence the spring constant of the spring is 7167.27N/m

Answer:

As the temperature increases, the volume of the material also increases. This is known as thermal expansion. It can also be explained as the fractional change in the length or volume per unit change in the temperature.

The relation between alpha, beta, and gamma is given in the form of a ratio and the ratio is 1:2:3 and can be expressed as:

alpha=fracbeta2=fracgamma3

Following is the relation between the three:

L = L (1 + α.ΔT)

Where, α is the coefficient of linear expansion  

A = A (1 + β.ΔT)

Where, β is the coefficient of aerial expansion

V = V (1 + γ.ΔT)

Where, γ is the coefficient of cubical expansion  

V = V + γV.ΔT

V = V (1 + γ.ΔT)  

L3 = L3 (1 + α.ΔT)3

L3 = L3 (1 + 3α.ΔT + 3α2.ΔT2 + α3.ΔT3)

L3 = L3 (1 + 3α.ΔT)

Alpha, beta, and gamma are related to one another in the form of a ratio, and that ratio is 1:2:3, and yes they are universal constants.

A substance's volume expands while its mass stays constant. Heating is typically the cause of expansion. When a substance is heated, the molecular bonds separating its particles weaken, the particles move more quickly, and the substance expands as a result.

Determine the relation as shown below,

L = L (1 + α × Δ T)

here, α is the coefficient of linear expansion  

A = A (1 + β × Δ T)

here, β is the coefficient of aerial expansion

V = V (1 + γ × Δ T)

here, γ is the coefficient of cubical expansion  

V = V + γ × V × Δ T

V = V (1 + γ × ΔT)  

L3 = L3 (1 + α × Δ T)3

L3 = L3 (1 + 3α × ΔT + 3α2 × ΔT2 + α3 × ΔT3)

L3 = L3 (1 + 3α × Δ T)

where Q is the quantity of electricity and it is measured coulombs (C); 2.8 × 10⁻⁸ C or 0.000000028 C

I is current and it is measured in ampere (amps or A); unknown

t is time and it is measured in seconds (s); 0.05 s
