PHYSICS MIDDLE SCHOOL

Can someone help me ASAP!!!! why does the united states still use the english system for everyday measurements which of the following is not a reason for worldwide use of the metric system instead

Answers

Answer 1
Answer: The US English System of measurement grew out of the manner in which people secured measurements using body parts and familiar objects. For example, shorter ground distances were measured with the human foot and longer distances were measured by paces, with one mile being 1,000 paces. Capacities were measured with household items such as cups, pails (formerly called gallons) and baskets.

Linh builds a circuit from the diagram shown. A rectangular box of lines with the long side vertical and an extra horizontal line about 2 thirds of the way up. The top line has a circle with an X in it labeled 1. The right side from top has a top circle 2 with an X in it then the connection with the extra line then a bottom circle 4 with an X in it. The extra line has a circle 3 with an X in it. The left side has a stack of horizontal lines near its bottom, which are, from top very short, short, very short, short. If Linh removes bulb 3, which bulbs will remain lit? 1 only

1 and 2 only

4 only

1, 2, and 4

Answers

If Linh removes bulb 3,the bulbs which will remain lit are 1, 2 and 4.

What is circuit?

The electric circuit provided with battery creating potential difference across resistance or capacitor or inductors.

When Linh removes the middle branch, the bulbs 1, 2 and 4 will be acting as resistor which are in series connection. The current flow will be same in all the resistors except 3.

Thus, If Linh removes bulb 3, the bulbs which will remain lit are 1, 2 and 4.

4. What type of smog do we experience in the United Sta5. Why is it harmful?6. What is one resultof air pollution?7. Rain that contains more acid than normal is called8. How does acid rain harm our environment?How are Americans improving air quality?

Answers

4. We experience brown smog, especially in Denver and LA.
5. It is harmful because brown smog is composed of NOx's which react with water vapor in the atmosphere and create acid rain.
6. One result of air pollution is acid rain.
7. Acid rain.
8. Acid rain harms our environment by decreasing the pH of the soil which can harm plant life and bacteria, disrupting the ecosystem.
9. Americans are improving air quality by passing laws such as the Clean Air Act of 1990 which puts limits on the amount of air pollutants cars, factories, ect can release into the atmosphere.

Side note: if you enjoy learning about this sort of thing or how humans impact the world, and haven't taken AP Environmental Science you totally should. It's a very eye opening class and I enjoyed it very much this year!

What are the four most common gases in dry air?

Answers

The four most common gases in dry air are nitrogen, oxygen, carbon dioxide, and water vapor.

The four most common gases in dry air are nitrogen, oxygen, carbon dioxide, and water vapor.

Nitrogen is the most abundant gas in dry air, making up about 78.6% of the air.

Oxygen is the second most abundant gas, accounting for approximately 20.9% of the air.

Carbon dioxide is present in small amounts, around 0.04%, but it plays an important role in the Earth's carbon cycle and climate. Water vapor, despite being a variable component, can make up around 0.5% of the air.

During which season is the sun highest in the sky? A.
spring

B.
summer

C.
fall

D.
winter

(this is science)

Answers

Answer: B.  summer

Explanation:

Seasons occur due to tilt of the Earth. Earth's axis is tilted 23.5° from the vertical. As the Earth revolves around the Sun, sometimes the Northern hemisphere points towards the Sun and sometimes away.

When the northern hemisphere points towards the Sun, Summer occurs and in the Southern hemisphere, winter occurs. In Summers, the Sun is highest in the sky and the sun rays fall directly. The duration of day time is greatest in summers. In winters, the Sun is lowest in the sky and sun rays fall obliquely.

summer i think because thats when its warmest
