How do the particles in a Longitudinal Wave move?

A) Parallel to the direction of the wave
B) Perpendicular to the direction of the wave
C) Particles do not move
D) The particle is the wave (wave packet)

Answers

Explanation:

In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions. Pick a single particle and watch its motion.

complete circuit. The ammeter reads 0.50 ampere (current).

a. Determine the resistance of Rz.
R2

Answers

Complete question is;

A 50.-ohm resistor, an unknown resistor R, a 120-volt source, and an ammeter are connected in a complete circuit. The ammeter reads 0.50 ampere.

A) Calculate the equivalent resistance of the circuit shown.

B) Determine the resistance of resistor R shown in the diagram.

Answer:

A) R_eq = 240 Ω

B) R = 190 Ω

Explanation:

A) To get the equivalent resistance, we will use the formula;

R = V/I

Where;

V is Voltage

I is current

R is equivalent resistance

From the question, V = 120 V and I = 0.5A

Thus;

R_eq = 120/0.5

R_eq = 240 Ω

B) From the image, we see that the resistors are connected in series.

Formula for resistors in series is;

R = R1 + R2 +..... Rn

Thus;

240 = 50 + R

R = 240 - 50

R = 190 Ω

A) The equivalent resistance of the circuit shown will be  240 Ω.

B) The resistance of resistor R will be 190 Ω

What is resistance?

Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.

The given data in the problem is;

R is the resistance = 50.-ohm

v is the voltage = 120-volt source

I is the value of the current =0.50 ampere.

A) The equivalent resistance of the circuit shown will be  240 Ω.

According to ohm's law

[tex]\rm R= \frac{V}{I} \\\\ \rm R= \frac{120}{0.5} \\\\ \rm R=240 \ ohm[/tex]

Hence the equivalent resistance of the circuit shown will be 240 Ω.

B) The resistance of resistor R will be 190 Ω

The given resistors are connected in the series;

R = R1 + R2 +..... Rn

240 = 50 + R

R = 240 - 50

R = 190 Ω

Hence the resistance of resistor R will be 190 Ω

A van of mass 2500kg travelling at a velocity of 12 m/s collides with a stationary car of mass 700kg. The vehicles move together after the impact. Calculate their velocity.​

Answers

Answer: 9.375m/s

Explanation: This is an inelastic collision, so the formula is mv1+mv2=(m1+m2)v-final. My work is a follows:

2500kg(12m/s) + 700kg(0m/s)=(2500kg+700kg)(v-final)

30,000kg(m/s)+0=3200kg(v-final)

30,000kg(m/s)/3200kg=9.375m/s

What is the equation used to find the image distance? Identify each variable

Answers

Answer:i f I understand your question correctly, the formula is as follows:

Note: The sign convention is based on distances which are measured from the lens to the object or image of regard. Distances measured in the same direction the light is moving are positive and distances measured in the opposite direction the light is moving are negative.

The measurements are in meters

The “ambient” index of refraction is assumed to be n=1.00

The inverse of the object distance plus the dioptric power of the lens (convex—positive and concave—negative) equals the inverse of the image distance.

Or 1/Od +Dl =1/Id

Please note, it has been a long time since I thought about teaching this concept to students.

When drawing a vector, you should represent the magnitude of the vector by the length of the arrow. A. True O B. False​

Answers

Answer: A. True

Explanation:

Answer:

A. True

Explanation:

A vector in this sense is a thing that has both magnitude (length) and direction.

Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.

This doesn't give any information about where you started or any information about where you ended up after those 2 hours.

This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.

Velocity is a vector.

How the choice of building materials and techniques can help them cool down faster, after heating up.

Answers

Answer:

The choice of building materials and techniques can help them cool down faster, after heating up is explained below in brief details.

Explanation:

Building materials

Buildings that are composed of rock, bricks, or pavement, or inserted into the territory, can seem cooler thanks to the great "thermal mass" of these elements – that is, their capability to assimilate and discharge heat gently, thereby softening temperatures over time, producing daytime cooler and night-time warmer.

For an object falling at the terminal velocity, list all the forces (magnitude and direction) acting it?

Answers

Answer:

Three stages of falling

There are three stages as an object falls through a fluid:

at the start, the object accelerates downwards due to the force of gravity

as the object's speed increases, frictional forces such as air resistance or drag increase

at terminal velocity, the weight of the object due to gravity is balanced by the frictional forces, and the resultant force is zero

In terms of activation energy, why does increasing the temperature of a reaction make it proceed more quickly? A. Increasing the temperature increases how many reactant molecules reach activation energy. B. Increasing the temperature reduces the activation energy C. Increasing the temperature increases the potential energy of the reactants D. Increasing the temperature makes the molecules move slower.​

Answers

Answer:

A. Increasing the temperature increases how many reactant molecules reach activation energy.

Explanation:

The correct statement is " Increasing the temperature increases how many reactant molecules reach activation energy"

What is activation energy?

"Activation energy is the minimum amount of energy that must be provided to molecules /atoms of the compounds/ elements to result in a chemical reaction."

When temperature increases the kinetic energy of the molecules increases hence more reactant molecules reach the activation energy.

So it can be concluded that by Increasing the temperature increases how many reactant molecules reach activation energy.

Explain the melting of a solid in terms of molecules and energy​

Answers

When you melt a solid the heat creates energy, when you heat up molecules they will move quicker and start to somewhat break apart into a liquid structure.

Heat generates energy when you melt a solid; as you heat up molecules, they move faster and begin to break apart into a liquid form.

What is the melting point?

The melting point is the point at which a substance transforms from a solid to a liquid.

The melting point of a liquid is the temperature at which it transforms from a solid to a liquid at atmospheric pressure. This is the point where the liquid and solid phases are in balance.

Heat generates energy when you melt a solid; as you heat up molecules, they move faster and begin to break apart into a liquid form.

The kinetic energy of the molecule is due to the movement of the molecule as the temperature of the system increases the melting point comes closer.

As the temperature increases the kinetic energy of the molecule increases.

Hence the energy, melting point, and temperature relatively affect each other.
