Imagine that you are sitting in a closed room (no windows, no doors) when, magically, it is lifted from Earth and sent accelerating through space with an acceleration of 1g (9.8 m/s2). According to Einstein's equivalence principle, which of the following is true?You won't feel any change and will have no way to know that you've left the earth.
You'll feel a force that will cause your head to repeatedly bang into the ceiling.
You'll know that you left the Earth because you'll be floating weightlessly in your room.
You'll know that you left the Earth because when you drop a ball it will fall sideways.

Answers

Answer 1
Answer:

Answer:

You won't feel any change and will have no way to know that you've left the earth.

Explanation:

One of the formulations of the principle says that the properties of an inertial system under the effect of a gravitational field are the same as a non-inertial(accelerated) system. The inertial system under the effect of a gravitational field occurs when you are in the room on earth, and when the room is sent accelerating through space you have the non-inertial system. Both have the same properties, so it's impossible to tell the difference if you can't look outside.

Which statement best describes the relationship between forces?a.Magnetic and electrical forces are the most alike because they are both caused by positive and negative charges.

b. Gravitational and magnetic forces are the most alike because they are both types of charges that occur in nature.

c. Nuclear and magnetic forces are the most alike because they are both related to mass and weight.

d. Strong nuclear force is most like electric because they are both related to distance.

Answers

The statement which best describes the relationship between forces is the last option represented above d. Strong nuclear force is most like electric because they are both related to distance. According to the general characteristics, it can't be caused by positive or negative charges and does not relates to mass and weight.

Answer:

d) strong nuclear force is most like electric because they are both realted to distance.

Why is a raindrop a particularly damaging element to soil

Answers

Answer:

Raindrops are considered damaging to the soil in the following ways:

  1. If it is too wet or too dry, nutrients in the soil can run off and not make it to the plants' roots, leading to poor growth and overall health.
  2. over-watering or too much rain can also lead to bacteria, fungus, and mold growth in the soil
  3. If the average rainfall is much lower or higher than the ideal, it can lead to significant problems, from drowned crops to lower yields.
  4. The soil can also start to collect bacteria, mold, and fungus, which can then be absorbed by the plant. While this isn’t as common in crops as it is in indoor plants, poor drainage and irrigation systems can lead to these types of growths taking control over your crops.
  5. raindrops when it is excessive can lead to erosion and leaching of the soil
  6. soil loss is mostly affected by increasing runoff discharge of rainwater                                      

Cheers!

All life that we know of is based on carbon. Carbon's ability to form many chemical bonds is an important characteristic that allows it to form the basis of life. Identify two other elements that can probably also form a large number of bonds and that probably have similar properties to carbon.

Starch and cellulose have the same substance but different structures. They are both polysaccharides. The basic unit of a polysaccharide is the glucose. Glucose, which contains carbon, hydrogen, and oxygen, have two forms. The alpha-glucose with an alcohol group attached to carbon 1 is down and the beta-glucose with the alcohol group attached to carbon 1 is up. Starch is the alpha-glucose while cellulose is the beta-glucose. Starches are linked into a straight chain whereas the cellulose are connected like a pile of stack paper. When the human body eats starch, it can digest the starch but not the cellulose because it has no enzyme that can break it down.

B. Loop of wire
C. Permanent magnets
D. Battery


PLS HELP

Answers

Commutator is part of a motor causes its electromagnet to turn in the same direction consistently, transforming electrical energy into mechanical energy.

What is energy?

Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.

A commutator is a rotary electrical switch in certain types of electric motors and electrical generators.
