Why are there so few eclipses in 2014? Shouldn't there have been a lunar eclipse every month?
- Because the Moon was not close enough to the Earth to be completely in its shadow.
- Because there is not a New Moon every month.
- Because the Moon's orbit around Earth is tilted.
- Because the Earth is tilted.
Answer:
Because there is not a New Moon every month.
Explanation:
hope it helped!
There are so few eclipses in 2014 because there is not a New Moon every month. The correct option is B.
What are lunar eclipses?When the moon is covered by the shadow of the earth, a lunar eclipse happens. The following total lunar eclipse won't take place until March 14, 2025, thrilling skywatchers throughout the world on the last total lunar eclipse, which took place on November 8, 2022.
In order for the Earth's shadow to be cast onto the Moon by the Sun, the Moon and Earth must be in the same orbital plane as the Sun. This is why, as opposed to monthly, lunar eclipses only take place one or two times a year on average.
It is advised to avoid eating anything cooked, even raw, right before the lunar eclipse. This is due to the widespread perception that an eclipse favors the growth of microbes in food.
Therefore, the correct option is B. Because there is not a New Moon every month.

What two gases in the atmosphere do animals and plants need to breathe and grow?
Answer: Explanation:
Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.

4. The Himalayan Mountains tower as high as 8,854 m above sea level. The rate of plate motion is about 10 cm per year. Use the diagram to explain how the Himalayas formed. Predict how they might look in 10 million years.
Answer:
Forty million years ago, the continent of India, which was being carried northward by the Indo-Australian plate, collided with Asia forming the Himalayan mountain range (fold mountains). Since the initial encounter, the subcontinent of India has moved 2,000 kilometers farther north at a rate of 5 centimeters a year, sliding beneath Asia as it moves. In 10 million years India will plow into Tibet a further 180km. This is about the width of Nepal.

What does it mean when something asks to put a proposed hypothesis?
Do nutrients cause seagrass to grow more in this area? If so, are both nitrogen and phosphorus equally important? Explain your answer.
Seagrasses are a vital part of the marine ecosystem..
Seagrasses are submerged flowering plants found in shallow marine waters, such as bays and lagoons and along the continental shelf in the Gulf of Mexico. A vital part of the marine ecosystem due to their productivity level, seagrasses provide food, habitat, and nursery areas for numerous vertebrate and invertebrate species. The vast biodiversity and sensitivity to changes in water quality inherent in seagrass communities makes seagrasses an important species to help determine the overall health of coastal ecosystems. Seagrasses perform numerous functions:
Stabilizing the sea bottom
Providing food and habitat for other marine organisms
Maintaining water quality
Supporting local economies

When you drop something, first of all it accelerates.
The faster it falls, the bigger the force of ______ that acts on it.
choose from the list to complete the sentence:
friction gravity air pressure
note: apparently the answer is friction but it doesn't make sense to me so please explain.
The faster an object is going, the more resistance there will be. An example of this would be if you're running the faster you run, the more air is going against you.

What are the four forms of matter that waves can travel through?
Answer:
It can be a solid, liquid, gas,plasma,etc. When waves travel through a medium, the particles of the medium are not carried along with the wave.For example, water waves have to travel in water. Sound waves need a solid, a liquid or a gas to travel in.
The four states of matter are gas, liquid, solid and plasma. Waves can travel through all these states of matter but by different transfer modes.
What are waves?Waves are energy transfer through matter. There are two types of waves namely, mechanical waves and electromagnetic waves. Mechanical waves can travel through a medium only whereas, electromagnetic waves can travel through vacuum also.
The four states of matter are liquid , gas , solid and plasma. All of these states are allotting waves to pass through. Through solids the energy is transferred by conduction. and in gases and liquids, convection is the mode for energy transfer.
Only electromagnetic waves can pass through plasma state of matter. When the frequency of the waves is greater than the plasma frequency, then electromagnetic waves can pass through it.

You probably use the term heat many times a day. As an example, when you cook, dinner, you heat your dinner on a hot stove. When you place a piece of cool metal in the sun, it is heated by the sun’s energy. Why is heat the correct term to use in these examples?
A. They show that when objects are touching, they are the same temperature.
B. They show that heat flows from something warmer to something cooler.
C. They indicate that heat is created to raise the temperature of something.
D. They indicate that the kinetic energy of the particles decreases when something is heated.
Answer: Pretty sure it is B
Explanation:
When you cook, dinner, you heat your dinner on a hot stove. When you place a piece of cool metal in the sun, it is heated by the sun’s energy. Heat is the correct term to use in these cases because they show that heat flows from something warmer to something cooler. So, option(B) is correct.
What is heat?As a result of a temperature difference, energy is transferred from one body to another and is known as heat. The hotter body transfers energy—heat flows—from the cooler body when two bodies with different temperatures are brought together.
An increase in the temperature of the colder body and a reduction in the temperature of the hotter body are typically, though not always, the results of this energy transfer.
A substance can absorb heat without increasing in temperature by transitioning from one physical state (or phase) to another, such as melting, sublimation, boiling, or shifting from one solid form to another (usually called a crystalline transition).

Consider these scenarios.
Scenario 1- Your ear is resting on the end of a metal bar that is stuck by a drumstick about 7 meters away from your ear.
Scenario 2- You are about 7 meters away from a metal bar that is struck with a drumstick. The sound travels through the air to your ear.
In which of these scenarios would the sound of the drumstick hitting the metal bar get to you in the least amount of time? Explain your answer.
Answer:
The sound of the drumstick hitting the metal bar will get to me in a shorter amount of time in Scenario 1. The sound wave will travel faster in the metal bar than through the air because the speed of sound waves in solids is faster than it is in gases.

What is the answer to mgh =1/2 mv^2 + 1/5 mv^2 ???
Answer:
v = sqrt((10/7)gh)
Explanation:
The given equation is:
mgh = (1/2)mv^2 + (1/5)mv^2
To solve for v, we can start by simplifying the right side of the equation:
mgh = (7/10)mv^2
Dividing both sides by (7/10)mv^2, we get:
mgh / (7/10)mv^2 = 1
Multiplying both sides by (10/7)m/gh, we get:
v^2 = (10/7)gh
Taking the square root of both sides, we get:
v = sqrt((10/7)gh)
Therefore, the solution for v in terms of m, g, h is:
v = sqrt((10/7)gh)
