Answer:

Explanation:

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. ... Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time.

Answer:

1788.402 MJ

Explanation:

Work done = Force (N) x distance (m)

First we have to convert distance into metres:

173.8 x 1000 = 173,800 m

Then plug these values into the equation above:

173,800 x 10290 = 1788402000 J

The reason it's Joules (the unit for energy) is because work done = energy transferred

Now we have to convert Joules into Mega Joules:

1 J = 1/1000000 MJ

1788402000 J = 1788402000/ 1000000 = 1788.402 MJ

Answer:

A

Explanation:

The image that shows an alignment of earth, moon and sun during spring tide is option A. All of them will be in a straight line.

A spring tide is a type of tide that occurs when the Earth, sun, and moon are aligned in a straight line. During a spring tide, the gravitational pull of the sun and the moon combine, resulting in higher-than-normal high tides and lower-than-normal low tides.

During a spring tide, the position of the sun, moon, and earth is aligned in a straight line. The gravitational force of the moon and sun both act upon the oceans of the Earth, creating a combined effect that results in unusually high tides.

During a spring tide, the moon is either new or full, which means it is in a position that aligns with the sun and Earth. The gravitational pull of the moon and sun reinforce each other, creating a stronger gravitational force on the Earth's oceans.

This causes the water level to rise higher than normal during high tide and lower than normal during low tide. Here, image A shows the correct alignment.

Explanation:

Answer:

ΔK = -6 10⁴ J

Explanation:

This is a crash problem, let's start by defining a system formed by the two trucks, so that the forces during the crash have been internal and the moment is preserved

initial instant. Before the crash

        p₀ = m v₁ + M 0

final instant. Right after the crash

        p_f = (m + M) v

        p₀ = p_f

        mv₁ = (m + M) v

        v = [tex]\frac{m}{m+M} \ v_1[/tex]

we substitute

        v = [tex]\frac{20}{20+40}[/tex]   3

        v = 1.0 m / s

having the initial and final velocities, let's find the kinetic energy

        K₀ = ½ m v₁² + 0

        K₀ = ½ 20 10³ 3²

        K₀ = 9 10⁴ J

        K_f = ½ (m + M) v²

        K_f = ½ (20 +40) 10³  1²

        K_f = 3 10⁴ J

the change in energy is

       ΔK = K_f - K₀

       ΔK = (3 - 9) 10⁴

       ΔK = -6 10⁴ J

The negative sign indicates that the energy is ranked in another type of energy

Answer:

E = 24000 N/C = 24 KN/C

Explanation:

The electric field experienced by a test charge is given by the following formula:

[tex]E = \frac{F}{q}\\\\[/tex]

where,

E = Electric Field = ?

F = Force of attraction = 3 x 10⁻⁶ N

q = Charge on piece of lint = 1.25 x 10⁻¹⁰ C

Therefore, using these values in the equation, we get:

[tex]E = \frac{3\ x\ 10^{-6}\ N}{1.25\ x\ ^{-10}\ C}\\\\[/tex]

E = 24000 N/C = 24 KN/C

I hope this helps a little bit.

The statement is false.

Answer:

TRUE

Explanation:

Answer:

A. 13.3

Explanation:

First, we find the velocity of the electron in meters/sec, as follows:

[tex]v = \frac{d}{t}\\[/tex]

v = velocity of electron = ?

d = distance between plates = 2 cm = 0.02 m

t = time elapsed = 1.5 x 10⁻⁸ s

Therefore, using these values in the equation, we get:

[tex]v = \frac{0.02\ m}{1.5\ x\ 10^{-8}\ s}\\\\v = 1333333.33\ m/s[/tex]

Now, we convert this to million m/s:

[tex]v = (1333333.33\ m/s)\frac{1\ million\ m}{100000\ m}\\\\v =13.3\ million\ m/s[/tex]

Therefore, the correct answer is:

A. 13.3

Answer:

a) time taken = 1.427 s

b) final speed before hitting the ground = 14 m/s

Explanation:

height of cliff = 10 m

acceleration due to gravity = 9.81 [tex]m/s^{2}[/tex]

time taken for stone to reach bottom of cliff = ?

velocity of stone just before hitting the ground = ?

To find the time taken, we will use Newton's equation of motion

using

[tex]v^{2} = u^{2} + 2as[/tex]

where

v = final speed of stone before hitting the ground

u = initial speed of the stone (u = 0 since the stone started falling from rest)

a = acceleration due to gravity = 9.81 [tex]m/s^{2}[/tex]

s = height of the cliff = 10 m

Solving, we have

[tex]v^{2} = 0^{2} + 2(9.81 * 10)[/tex]

[tex]v^{2} = 2*98.1[/tex]

[tex]v^{2} = 196.2[/tex]

[tex]v=\sqrt{196.2} = 14 m/s[/tex]

From the first equation of motion,

[tex]v = u + at[/tex]

where t = time taken for stone to reach bottom of cliff

imputing values, we have

[tex]14 = 0 + (9.81 * t)[/tex]

[tex]t = \frac{14}{9.81} = 1.427 s[/tex]

Answer:

wave

Explanation:

A wave is defined as the disturbance that causes the movement of energy. The energy is transferred as the waves move from one place to another. A medium is required for the transfer of energy. Usually a wave travels through air or water. The process is carried on at a specific speed that is termed as the speed of propagation.
