Tony is creating a model showing how Earth rotates over the course of one day. He uses a globe to represent Earth.
Tony knows that Earth spins on its axis, completing one rotation every 24 hours. He slowly spins the globe counterclockwise, completing one rotation in about 6 seconds.
In Tony's model, 1 second of rotation represents about
hours.

Answers

Answer:

1 second of rotation represents 4 hours

Explanation:

1 sec = 4 hours

2 sec = 8 hours

3 sec = 12 hours

4 sec = 16 hours

5 sec = 20 hours

6 sec = 24 hours

Tony is creating a model showing how Earth rotates over the course of one day. In Tony's model, 1 second of rotation represents about  four hours.

What is rotation ?

The circular movement of an item about a primary axis is referred to as rotation or spin. A revolving object in two dimensions only has one conceivable central axis and can revolve either clockwise or counterclockwise. There are many conceivable central axes and rotating orientations for a three-dimensional object.

The positions of the various parts of the Earth in regard to the Sun fluctuate as it revolves on its axis. A city on Earth will rotate to face away from the Sun 12 hours after it faces the Sun at midday. Sunrise, sunset, day, and night are caused by the relative locations of the Earth and the Sun throughout a 24-hour rotation.

Thus, In Tony's model, 1 second of rotation represents about  four hours.

Which event may occur when ocean salinity increases?

mass of water increases
freezing point of water increases
sunlight in deeper locations decreases
amount of dissolved gases in water increases

Answers

Answer:

sunlight in deeper location decreases

Explanation:

because the more salinity water has the harder it is to see and the harder it is for light to travel through the ocean

sunlight in deeper locations decreases, This event may occur when ocean salinity increases. Hence option C is correct.

What is sunlight ?

Sunlight is a kind of electromagnetic radiation emitted by the Sun, namely infrared, visible, and ultraviolet light. When the Sun is above the horizon, sunlight is scattered and filtered through the Earth's atmosphere and appears as daylight. Sunlight, a mix of brilliant light and radiant heat, is experienced when direct solar radiation is not hindered by clouds. Sunlight is dispersed when it is obstructed by clouds or reflected off other things. According to sources, a worldwide average of between 164 and 340 watts per square metre over a 24-hour day is estimated by NASA to represent roughly a fifth of the Earth's typical total sun irradiation.

Describe how voltage, current and resistance behave in a parallel circuit.

Will give BRAINLIEST to best answer.

Answers

Answer: the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather than add to make the total.

The voltage is equal across all components in a parallel circuit. The total circuit current is equal to the sum of the individual branch currents. While individual resistances diminish to equal a smaller total resistance rather than add to make the total.

What is Voltage?

In physics, the voltage may be characterized as a quantitative expression of the potential difference in charge between two points in an electrical field. It is also called electromotive force (EMF).

According to the context of this question, the current in a parallel circuit splits into different branches and then combines again before it goes back into the supply. When the current splits, the current in each branch after the split adds up to the same as the current just before the split.

In a parallel circuit, the net resistance decreases as more components are added, because there are more paths for the current to pass through. The two resistors have the same potential difference across them.

Therefore, the relation of voltage, current, and resistance behave in a parallel circuit is well described above.
