Stars appear to move at _______ through the sky every night.
A.
unpredictable speeds
B.
different speeds
C.
the same speed
D.
a very fast speed

Answer:

Because the force required to produce this acceleration equals the mass of the car x acceleration, the group of the car is the same but the acceleration is a lot more hence a much bigger force is required. So this is why it's harder for cars to corner at a high speed rather than lower.

Answer:

Vehicles are heavy and have a lot of inertia. This means that if you drive too fast on a curve, your vehicle will keep going straight instead of going around the curve, no matter how hard you drive or slow down to keep it in your lane. Centrifugal force creates a strong outward pull on your vehicle. So all you need to do is slow down before entering a corner. Reducing your speed when you are already on a bend can cause your car to skid.

Explanation:

Answer:

All of them are correct

Explanation:

Earth is revolving around the sun in an elliptical orbit, with sun as one of its focus. So, the correct shape is A.

Newton's law of gravity states that, every body in the universe attract each other with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Here,

Earth is revolving around the sun in an elliptical orbit, with sun as its focus.

According to Kepler's law of orbits, every planet moves in an elliptical orbit with sun as one of its focus.

From, Newton's law of gravity and Kepler's law of orbital motion, we can say that the earth is moving in an elliptical orbit because, the earth is experiencing gravitational force of attraction due to the sun at the centre and also due to the other planets revolving in the solar system.

Due to the overall gravitational force, the earth will have to adjust the orbital motion in order to attain stability. As a result, the orbit of earth will have a distortion from its circular shape, forming an elliptical shape for orbit, which is a stable shape.

Hence,

Earth is revolving around the sun in an elliptical orbit, with sun as one of its focus. So, the correct shape is D

Answer: When they're the same temperature.

...

Thermal equilibrium. The condition under which two substances in physical contact with each other exchange no heat energy. Two substances in thermal equilibrium are said to be at the same temperature.

Answer:

196J or 200J

Explanation:

Potential Energy = mgh

m( mass) = 10gm

h ( height) = 2m

g = 9.8 or 10 m/s ^2 ( choose whichever one is taught to you, usually in my school its 9.8 if the value isn't given )

PE = 10 × 10 × 2 = 200 J

or

PE = 10 × 9.8 × 2 = 196 J

Hope it helps

Answer:

200J

Explanation:

2m x 10gm = 200

Answer: Get stronger. Strength is critical to running fast because the more force you can exert against the ground the faster you can run.

Apply your new strength. Being strong is important for sprinting, but the ability to apply it is even more important. Sprinters move in a horizontal direction.

Take longer steps more quickly. Today, the concept of exerting more force against the ground is very popular for improving speed. ...

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.

Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)

Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.

2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.

3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.

The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.

Explanation:

The answers that apply for the stars are 1,2,4 and 5. Stars usually seem bright if they are close to Earth.

A star is a heavenly body made up of a brilliant spheroid of plasma held together by gravity. The Sun is the closest star to Earth.

Many additional stars may be seen with the normal eye at night, but due to their great distance from Earth, they appear as stationary points of light in the sky.

The answers that apply for the stars are as follows;

1. Usually seem bright if they are close to Earth.

2. Stars are terrestrial bodies.

4. They generate their own energy.

Answer:

1. The field of biology concerned with the relationships between species and their physical environments.

2. Abiotic components are non-living chemical and physical factors in the environment that influence ecosystems in ecology and biology. The term "biotic" refers to a living part of an ecosystem, such as plants and animals.

3. Since photosynthesis is the primary source of oxygen in the atmosphere, it is vital to living organisms. Photosynthesis is the process by which green plants and trees produce food from sunlight, carbon dioxide, and water in the atmosphere: it is their primary source of energy.

4. Decomposers break down dead plants and animals and return nutrients to the soil. Carnivores get their nutrition by eating other species. Herbivores obtain their energy from the plants they consume. Plant and animal forms of nutrition are used by omnivores.

5. Energy is required for all living organisms to develop and reproduce, sustain their structures, and react to their surroundings. Metabolism is a series of life-sustaining chemical processes that enable organisms to convert chemical energy stored in molecules into energy for cellular processes.

6. Organisms compete for resources such as air, water, food, and space in order to live. In areas where these are sufficient, organisms coexist peacefully, and in areas where resources are plentiful, the ecosystem boasts a diverse range of species (diversity).

7. The word "niche" is used in ecology to describe the role that an organism plays in a group. The physical and environmental conditions that a species needs (such as temperature or terrain) as well as the relationships it has with other species make up a species' niche (like predation or competition).

8. Prey animals are species that serve as food for predatory animals. Many predators could end up as food for larger predators. The top predator is a predator species that does not prey on other animals.
