A charged particle is placed in a space. The particle experiences a force. What can be concluded?
A.
The space contains a magnetic field.
B.
The space contains an electric field.
C.
The space has a charge opposite to the particle's.
D.
Oppositely charged particles must be present.
Answers
Answer: A.
The space contains a magnetic field
Explanation:
A charged particle is surrounded by electric field and exerts force on other charges in the field, attracting or repelling them.
But a charged particles in a magnetic field can escape into infinity without ever stopping due to magnetic force. We can therefore conclude that the space contains a magnetic field

6.
Answer:
45 meters
Explanation:
notice that is you multiply the time with the speed the units cancel to get distance.
therefore
distance=velocity(time)
distance=(3)15
distance =45 meters
7.
Answer:
1. the speed is constant
2. the average speed is .5 m/s
Explanation:
I have attached a graph of the data in excel.
from excel i got the equation of the line to be y=.5x with y being distance and x being time.
the function is a position function so if you take the derivative of it you get the velocity which is .5.
since the derivative is a constant the the speed does not change and the average velocity is the derivative.

The woman supports a 100 N load with the friction free pulley system shown below. Fill in the spring scale readings that show how much force she must exert.
Answers
Answer:
1. 100N 2. 50N 3. 50N
Explanation:
The spring scale reading that shows how much force she must exert is 1. 100N 2. 50N 3. 50N.
What is the spring scale?A simple and affordable way to determine mass is by using spring balances. The mass is suspended from the end of the spring, and the spring's deflection as a result of the mass's downward gravitational pull is measured in relation to a scale.
The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains."
One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.
Therefore, her required force is indicated by the spring scale readings of 1. 100N, 2. 50N, and 3. 50N.

b 100 m/s
C 10000 m/s
d 1000 m/s
Answers
Answer:
D) 1000 m/s
Explanation:
[tex]wavelength = \frac{velocity}{frequency}[/tex]
You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.

In terms of forces, what makes the arrow start moving?
Answers
Answer:
the answer is A force is a push or pull that changes the motion of an object. Forces can make objects start or stop moving, cause objects that are already moving to speed up or slow down, or make objects change direction. Force arrows are used to represent both the magnitude and direction of forces.

Increase in greenhouse gases in the atmosphere leads to climate change because these gases have what property?
A. They absorb infrared radiation
B.They transit visible light
Answers
The answer would be A. They absorb infrared radiation.
Water vapor, carbon dioxide, methane, and other trace gases in Earth's atmosphere absorb the longer wavelengths of outgoing infrared radiation from Earth's surface. These gases then emit the infrared radiation in all directions, both outward toward space and downward toward Earth.

For any energy source including batteries, there will be conduction of electricity if there is a potential
difference
similarity
Answers
Answer:
Difference
Explanation:
The electricity conduction happens when there is a flow of current. The flow of current from one point to another can only occur if there is a potential difference.
If there is not potential difference between two points the current will not flow and thus electricity conduction will also be not possible. The current in the circuit will flow from higher potential point to lower potential point.

1. What are three things you think of when you think of energy?
Answers

Food, wind, water.
Explanation:
This is supposed to be a personalized question so I answered with things that can make/give energy.
Answer:
This is personal question, very interesting! Depend on who is the person, where the person is working at, how old is that person - we can have various answers.
Personally, I think first about that human and other animals needs energy to survive, that means we need to eat, to drink; The plants need energy to survive too - that is the energy from the Sun.
Secondly, the human being needs such types of energy as electricity, wind, solar energy, etc. in oder to live. Even the acient people learnt to use solar and wind and water - natural energy from the nature.
Thirdly, the human being needs spiritual energy to have a good life.
Another specific terms of energy related to physics and chemistry, and even biology - actually are not in my mind in everyday life.
