Answer:

d) q=k

Explanation:

When a battery is "dead" it means that the chemical components are at equilibrium. When that occurs,

Δ

G

= 0, and Q = K.

A 'dead' battery mean chemically Q=1. At this position, the battery is at equilibrium condition, and considered as dead.

Dead battery is the battery in which no flow of electron take place as there is no potential difference.

Chemically, the battery is considered as dead battery, when there is no chemical process happens in battery.

Thus, a 'dead' battery mean chemically Q=1. At this position, the battery is at equilibrium condition, and considered as dead.

The radius of the given circular path moved by the proton which is perpendicular to a magnetic field of 0.87 T determined as 4 cm.

The magnitude of the magnetic force on the proton is determined using the following formula;

F = qvBsin(θ)

The centripetal force of the circular path is given as;

F = mv²/r

Solve the two equations together,

[tex]\frac{mv^2}{r} = qvBsin(90)\\\\r = \frac{mv}{qB}[/tex]

Where;

The speed of the proton is determined from its kinetic energy;

[tex]K.E = \frac{1}{2}mv^2\\\\ v= \sqrt{\frac{2K.E}{m} } \\\\v = \sqrt{\frac{2 \times 9.3 \times 10^{-15}}{1.67 \times 10^{-27}} } \\\\v = 3.33\times 10^6 \ m/s[/tex]

The radius of the circular path is calculated as follows;

[tex]r = \frac{(1.67 \times 10^{-27}) \times (3.33 \times 10^6)}{(1.6\times 10^{-19}) \times (0.87)} \\\\r = 0.04\ m\\\\r = 4 \ cm[/tex]

Sound waves cannot travel through empty space

sound can travel through liqui

Sound waves cannot travel through empty space but can travel through liquids. Waves make the particles of matter up and down but do not along with them. The light waves are not true mechanical waves. Therefore, options (A), (B), (C), and (E) are correct.

Sound can transmit through liquids, gases, and plasma as longitudinal waves, also known as compression waves. It needs a medium to propagate so it can be propagated through solids as both longitudinal waves and transverse waves.

Longitudinal sound waves contain alternating pressure deviations causing compression and rarefaction, while transverse waves have waves of alternating shear stress perpendicular to the direction of propagation.

Waves can make matter move up and down or from side to side but do not carry along with them. Light waves are not considered true waves because they carry without the involvement of the motion of matter.

After the collision, object X will move at a speed of 2 m/s in its original direction while object Y will move at a speed of 5 m/s in its original direction.

When the two objects collide but do not stick together, the type of collision is elastic collision.

In elastic collision, both momentum and kinetic energy are conserved.

mu₁ + mu₂ = mv₁ + mv₂

5m + 2m = mv₁ + mv₂

m(5 + 2) = m(v₁ + v₂)

7 = v₁ + v₂ -------- (1)

Apply the concept of one direction velocity;

u₁ + v₁ = u₂ + v₂

5 + v₁ = 2 + v₂

v₂ = v₁ + 3 ------ (2)

Solve (1) and (2) together;

7 = v₁ + v₁ + 3

4 = 2v₁

v₁  = 2 m/s

v₂  = 2 + 3 = 5 m/s

Thus, after the collision, object X will move at a speed of 2 m/s in its original direction while object Y will move at a speed of 5 m/s in its original direction.

Electromagnetic radiation are a group of waves which are are produced by the vibrations of electromagnetic fields.

Electromagnetic radiation are a group of waves which are are produced by the vibrations of electromagnetic fields. Electromagnetic waves/radiation possess the ability to travel through vacuum (i.e. they do not require a material medium for their propagation) while also carrying radiant energy.

Electromagnetic fields which are the sources of electromagnetic radiation, exist as a result of the combination and interaction of travelling electric and magnetic field forces.

Electromagnetic radiations consists of the following waves: radio waves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays.

These waves have differing and unique properties such as wavelength, frequencies, ionizing properties, penetrating ability, sources as well as well as uses. However, they have a common property of velocity- they travel with the speed of light, 3.0 * 10⁸ m/s.

In addition to having the same velocity, all electromagnetic radiation exhibit interference and diffraction.

The low-pitched sound corresponds to the sound source moving away; its wavelength is longer. The high-pitched sound corresponds to the sound source getting closer; its wavelength is shorter.

Just took the quiz, and it said this answer was correct.

In this picture, The low-pitched sound corresponds to the sound source moving away; its wavelength is longer. The high-pitched sound corresponds to the sound source getting closer; its wavelength is shorter.

Wave is is a disturbance in a medium that carries energy as well as momentum . wave is characterized by amplitude, wavelength and phase. Amplitude is the greatest distance that the particles are vibrating. especially a sound or radio wave, moves up and down. Amplitude is a measure of loudness of a sound wave. More amplitude means more loud is the sound wave.

Wavelength is the distance between two points on the wave which are in same phase. Phase is the position of a wave at a point at time t on a waveform.

There are two types of the wave longitudinal wave and transverse wave.

Longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave. Sound wave is a longitudinal wave.

Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave. Light wave is a Transverse wave.

According to the Doppler's effect, a sound source moves away from the observer its wavelength increases and when it moves towards the observer the wavelength decreases.

The centripetal force of the rock tied to a string and swung in a circular path is determined as 1.65 N.

The angular speed of the rock is calculated as follows;

ω = 2π N

[tex]\omega = 35^0 \times \frac{2 \pi \ rad}{360^0} \times \frac{100}{3\min} \times \frac{1 \min}{60 \ s} \\\\\omega = 0.339 \ rad/s[/tex]

The centripetal force of the rock is calculated from the product of mass and centripetal acceleration as shown below;

Fc = ma

Fc = m(ω²r)

Fc = mω²r

Fc = 8 x (0.339)² x 1.8

Fc = 1.65 N

Given a set of vectors, you can determine if they are linearly independent by writing the vectors as the columns of the matrix A, and solving Ax = 0.

Explanation:

You may verify if a group of vectors is linearly independent by expressing the vectors as columns of the matrix A and solving Ax = 0.

A vector is a quantity or phenomena with magnitude and direction that are independent of one another. The phrase also refers to a quantity's mathematical or geometrical representation.

If no vector can be written as a linear combination of the others, a set of vectors is said to be linearly independent.

If no vector in a collection of vectors can be written as a linear combination of the ones mentioned before it, the set is said to be linearly independent.

A nontrivial linear combination yields the zero vector, the vectors are said to be dependent.

Answer: KE = 172.872 J

PE = 307.328 J

Explanation:

For KE: acceleration = change in velocity / time → 9.8 = final velocity - 0 (because initial velocity is zero) / 6s → final velocity after 6s = 58.8 m/s.

Now, plug this into: KE = 1/2(m)(v^2) → KE = 1/2(.1)(58.8^2) = 172.872 J.

For PE: Find the velocity after 10 s: acceleration = change in velocity / time → 9.8 = final velocity - 0 (because initial velocity is zero) / 10s → final velocity after 10s = 98 m/s.

Now, find the total height: (v final)^2 = (v initial)^2 + 2*a*d → 98^2 = 0^2 + 2*9.8*d → d = total height = 490 m.

Now, find the change in height after 6 s: (v final)^2 = (v initial)^2 + 2*a*d → 58.8^2 = 0^2 + 2*9.8*d → d = change in height after 6 s → 176.4 m

Now, subtract the change in height from the total height to get its height after 6s: 490-176.4=313.6m

PE = m*g*h → Pe=.1*9.8*313.6 = 307.328 J :)
