The relationship between electricity and magnetism is option 4 when the solar winds have interacted.

These two are phenomena that are inter-connected to each other that generated by the electromagnetic force.

When the electric charge produced the magnetic field so it induces the movement to the electric charge that generated the electric current.

hence, the fourth option is correct.

Answer:

The maximum height reached by the body is 313.6 m

The time to return to its point of projection is 8 s.

Explanation:

Given;

initial velocity of the body, u = 78.4 m/s

at maximum height (h) the final velocity of the body (v) = 0

The following equation is applied to determine the maximum height reached by the body;

v² = u² - 2gh

0 = u² - 2gh

2gh = u²

h = u²/2g

h = (78.4²) / (2 x 9.8)

h = 313.6 m

The time to return to its point of projection is calculated as follows;

at maximum height, the final velocity becomes the initial velocity = 0

h = v + ¹/₂gt²

h = 0 + ¹/₂gt²

h =  ¹/₂gt²

2h = gt²

t² = 2h/g

[tex]t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 313.6}{9.8} }\\\\t = 8 \ s[/tex]

Answer:

Explanation:

Since this is a distance v time graph, the slope of the line from 1s to 3s is the velocity. However, it looks like, at t=3, the velocity is 0, so getting the definite velocity is not going to happen. We can estimate it as closely as possible. Since the line is tending from the upper left to the lower right, the slope is negative, so the velocity is also negative. That leaves only C or D as our answers. And the slope is closer to -1 than to -5, so choice D. is the one you want.

The correct option about electric circuit diagram question is option C).

To solve this question we have to apply on ohms law on every given circuit and have to find out the value of current flowing through it.

The circuit in which the value of current flowing is equal to 12V that will be our answer.

Let us analyse option A

V = 12 V, R = 16 + 12 ohm = 28 ohm

I = V/R = 12/28

I = 0.42

Let us analyse option B

V = 12 V, R = 24 + 8 ohm = 32

I = V/R = 12/32 A

I = 0.375 A

Let us analyse option C

V = 12 V, R = 16 + 8 ohm = 24

I = V/R = 12/24 A

I = 0.50 A

Let us analyse option D

V = 12 V, R = 24 + 24 ohm = 48

I = V/R = 12/48 A

I = 0.25 A

From above analyses we can easily understand that the value of current is 0.5 A only in option C.

Thus, we can conclude that as after solving the circuits using ohms law we are getting the value of current as 0.5 A only in option C, So the correct option to the question will be option C.

Replace s and t with their units [ignore all constants]

[tex]a_0 = \frac{L}{T^2}\\[/tex]

[tex]a_0 = LT^{-2[/tex]

The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω

Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather than add to make the total.

Answer: 3

Explanation: If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

Explanation:

the second diagram depicts the phenomenon which is refraction and this stems from light moving from a medium to another......and in this case light moves from a less dense medium to a denser medium hence is refracted away from the normal(the straight line between the medium of air and glass)

PLS GIVE BRAINLY

Diagram B shows the refraction event and this is from light to medium, in this case, the light travels from a slightly narrower area to a compact area and is, therefore, further away from the normal (vertical line between the air and glass).

When a ray of light travels from a dense area to a rare place, it bends away from normal.

Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.
