Answer:

it's says that equal and opposite force are equal

that means earth and the small piece of junk orbitingexert equal forces so gravitational attraction happens

How much current is drawn by a television with a resistance of 30 ω that is connected across a potential difference of 120v?

melomori [17]

By using the Ohms law, we can calculate the current.

Ohms law,

$\frac{V}{I} = R$

Here, V is potential difference, and R is the resistance.

Given, $V=120 V$ and $R = 30 ohm$ .

Therefore, putting the given values in above relation , we get

$\frac{120V}{I} = 30 ohm$

or $I=\frac{120}{30} = 4 A$

Thus, the current is drawn by a television 4 Ampere

A car travels at a constant speed of 15 m/s for 2 minutes. The car increases its speed from 15 m/s to 25 m/s during the next min

Rzqust [24]

Answer:

Graph F.

Explanation:

From the question given above, the following information were obtained:

1. The car travelled at a constant speed of 15 m/s for 2 minutes. This implies that the car is already moving and the graph can not be drawn from the origin.

Therefore, graph G is wrong.

2. The car increases its speed from 15 m/s to 25 m/s during the next minute and travels at a constant speed of 25 m/s for 2 more minutes.

This implies that the graph of the motion will project upward.

Therefore, graph H and J are wrong.

From the illustrations above, graph F gives the correct discription for the motion of the car.

The index of refraction for red light in water is 1.331, and that for blue light is 1.340. If a ray of white light enters the wa

UNO [17]

Answer:

The underwater angles of refraction for the blue and red components of the light is 47.8° and 48.2°

Explanation:

Using the Snell's law

n1 * sin Ф1 = n2 sin Ф2

1 * sin 83 = n2 sin Ф2

Ф2 = $sin^{-1} (\frac{1}{n2} * sin 83)$

Red light

n2 = 1.331

Ф2 = $sin^{-1} (\frac{1}{1.331} * sin 83) = 48.2$ °

Blue light

n2 = 1.340

Ф2 = $sin^{-1} (\frac{1}{1.340} * sin 83) = 47.8$ °
