traveling a distance of 10 m?

A) Beaker

B) Voltmeter

C) Thermometer

D) Stopwatch

Answers

Answer 1

The stopwatch will be the most useful in determining the kinetic energy of a 50 g battery- powered car traveling a distance of 10 m.

What is kinetic energy?

Kinetic energy is the energy of a body possessed due to motion.

This means that for an object to possess kinetic energy, it must be in motion.

The kinetic energy is measured in Joules, which is a product of the mass of the substance and the time taken to travel a distance.

A stopwatch is an instrument used to measure time as one of the components of kinetic energy.

Therefore, the stopwatch will be the most useful in determining the kinetic energy of a 50 g battery- powered car traveling a distance of 10 m.

The law of reflection specifies that upon reflection from a downy surface, the slope of the reflected ray is similar to the slope of the incident ray.

The reflected ray is consistently in the plane determined by the incident ray and perpendicular to the surface at the point of reference of the incident ray.

When the light rays descend on the smooth surface, the angle of reflection is similar to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in a similar plane.

Three 20W resistors are connected in series across a 120 V generator. What is the total resistance of the circuit and what current flows in the circuit?

Answers

The total resistance and current flowing through the circuit is equal to 60 Ohms and 2 Amperes respectively.

Given the following data:

Resistors = 20 Ohms.

Voltage = 120 Volts.

How to determine the total resistance.

Since the three resistors are connected in series, we would calculate their total resistance by adding them up as follows:

RT = R1 + R2 + R3

RT = 20 + 20 + 20

RT = 60 Ohms.

Next, we would determine the current that is flowing through the circuit by applying Ohm's law.

A builder drops a brick from a height of 15 m above the ground. The gravitational field strength g is 10 N/ kg. What is the speed of the brick as it hits the ground?

Answers

The speed of the brick dropped by the builder as it hits the ground is 17.32m/s.

Given the data in the question;

Since the brick was initially at rest before it was dropped,

Initial Velocity; [tex]u = 0[/tex]Height from which it has dropped; [tex]h = 15m[/tex]Gravitational field strength; [tex]g = 10N/kg = 10 \frac{kg.m/s^2}{kg} = 10m/s^2[/tex]

Final speed of brick as it hits the ground; [tex]v = \ ?[/tex]

Velocity

velocity is simply the same as the speed at which a particle or object moves. It is the rate of change of position of an object or particle with respect to time. As expressed in the Third Equation of Motion:

[tex]v^2 = u^2 + 2gh[/tex]

Where v is final velocity, u is initial velocity, h is its height or distance from ground and g is gravitational field strength.

To determine the speed of the brick as it hits the ground, we substitute our giving values into the expression above.

[tex]v^2 = u^2 + 2gh\\\\v^2 = 0 + ( 2\ *\ 10m/s^2\ *\ 15m)\\\\v^2 = 300m^2/s^2\\\\v = \sqrt{300m^2/s^2}\\ \\v = 17.32m/s[/tex]

Speed of a wave

The speed of a wave v = fλ where

f = frequency and λ = wavelengthWhat is Wavelength?

This is the distance a wave travels in one cycle of the wave.

Making λ subject of the formula, we have

λ = v/f

Given that the range of frequencies of FM radio is 88.0 MHz to 108 MHz and

v = speed of electromagnetic wave = 3 × 10⁸ m/s, f' = lowest frequency = 88.0 MHz = 88.0 × 10⁶ Hz and f" = highest frequency = 108 MHz = 108 × 10⁶ HzThe longest wavelength, λ'

λ' = v/f'

= 3 × 10⁸ m/s ÷ 88.0 × 10⁶ Hz

= 0.0341 × 10² m

= 3.41 m

The shortest wavelength, λ"

λ" = v/f"

= 3 × 10⁸ m/s ÷ 108 × 10⁶ Hz

In outer space, a piece of rock continues moving at the same velocity for
thousands of years. What makes this possible?

Answers

The absence of external force in the outer space, allows the piece of rock to continue moving at the same velocity for thousands of years.

Absence of external force on the outer space

The outer space is almost an absolute vacuum, because it's nearly empty. There is no matter such as air in the outer space that will provide an external force needed to change the velocity of the piece of rock.

From Newton's first law of motion, an object in a state of rest or uniform motion in a straight line, will continue in that state unless it is acted upon by an external force.

Thus, the absence of external force in the outer space, allows the piece of rock to continue moving at the same velocity for thousands of years.

Frequency: Is the number of waves that pass a certain point in a specified amount of time.

Trough: The low point of the wave cycle.

Wavelength: The distance between two successive peaks.

Electromagnetic wave: One of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity.

Use the electron arrangement interactive to complete the table

Answers

The number of electrons that is needed to fill the following sublevels are:

1s = 2 electrons. 2s = 2 electrons. 2p = 6 electrons. 3s = 2 electrons.

What is the number of electrons needed to complete the table?

The formula to find this out is:

= 2 x (2 x Level +1)

1s = 0 levels

Number of electrons:

= 2 x (2 x 0 + 1)

= 2 electrons

2s = 0 levels

= 2 x (2 x 0 + 1)

= 2 electrons

2p = 1 level

= 2 x (2 x 1 + 1)

= 6 electrons

3s = 0 levels

= 2 x (2 x 0 + 1)

= 2 electrons

What is electron arrangement?

The electron arrangement is the way or process to arrange the electrons in an atom. The number of electron  needed per sublevel are expressed in following points.

The number of electron need to feel sublevel 1s is 2.The number of electron need to feel sublevel 2s is 2.The number of electron need to feel sublevel 2p is 6.The number of electron need to feel sublevel 3s is 2.

The image of the table which fill the sublevel is attached below. In this table all the electron is fulfilled with needed electrons.

Thus, the completed table using the electron arrangement interactive is attached below. In this table for sublevel 1s, 2s, 2p and 3s electron needed is 2,2,6 and 2 respectively.
