Which term is defined as the force applied to the object divided by the mass of the object?
speed
velocity
mass
acceleration
Answers
Answer:
acceleration
Explanation:
From the question: "FORCE... divided by the MASS..." is translated to a math equation as "F / m", where "F" is the force and "m" is the mass.
Now, the second Newton's law says "F = m . a ", where a is acceleration.
If you move m to the left side, clearly you have "F / m", and "a" is alone to the right. Math equation:
a = F / m
acceleration = force / mass

Which of the following gives the best description of the motion of electrons in a conductor?
A.
The electrons in conductors usually move in straight lines.
B.
The electrons in conductors are able to move about freely.
C.
The electrons in insulators are unable to move about freely.
D.
The electrons in conductors usually move in regular patterns.
Answers
Answer:
The correct answer is B. The electrons in conductors are able to move about freely.
Explanation:
The conductive materials are those that have an atomic structure that favors that the electrical charges can be easily moved inside. That is, a conductive material is one that allows the transport of electric charge, presenting little resistance to the movement of electric charge or electrons when an electric field is applied.
The arrangement and freedom of movement of the electrons along the atomic structure is what favors the circulation of electricity through the conductor.
So, the correct answer is B. The electrons in conductors are able to move about freely.

Work is the product of force and an object's
A. time
B. momentum
C. displacement
D. space
Answers
Answer:
C. displacement
Explanation:
Work is the product of force and an object's displacement. The correct answer is displacement and the correct option is option (C).
The result of a force and an object's displacement is called work. Work (W) is represented mathematically by the equation:
W = F × d
In the International System of Units (SI), the unit of work is the joule (J). When a force is applied to an object and it moves over a predetermined distance in the force's direction, work has been done.
No work is done if the item stays still or if the force and displacement are parallel to one another.
Therefore, Work is the product of force and an object's displacement and the correct option is option (C).

A uniform electric field contains a number of particles. All are experiencing forces in the same direction as the electric field. What can be concluded from this?
All the particles have negative charges.
All the particles have positive charges.
All the particles are charged, but they may be positive or negative.
All the particles must be uncharged.
Answers
Answer: D
All the particles must be uncharged
Explanation:
If all the particles are positively charged, then there will be force of repulsion between them which will give different directions away from each other. The same is applicable if they are all negatively charged.
If the particles are positively and negatively charged, their will be force of attraction between them which will give different directions towards each other.
For all to be experiencing forces in the same direction, We can conclude that
All the particles must be uncharged.
Answer:
This picture represents the electric field diagram between two particles with static charges.
Do the two particles have the same charge?
✔ no
If the particles are free to move, what affect will the two particles have on each other?
✔ They will attract each other.

What is the net force acting on a .15 kg hockey puck accelerating at a rate of 12 m/s2
Answers
Answer:
The net force is 1.8N
Explanation:
Given that the formula for force is Force = mass×acceleration. So you have to substitute the values into the formula :
[tex]force = mass \times acceleration[/tex]
Let mass = 0.15kg,
Let acceleration = 12m/s²,
[tex]force = 0.15 \times 12[/tex]
[tex]force = 1.8[/tex]
Answer:
1.8 Newtons
Explanation:
We want to figure out the net force acting on a 0.15 kg hockey puck that has an acceleration of 12 m/s². To solve this, we must apply Newton's Second Law of Motion which is denoted by the formula: f = ma.
Here, f is the force, m is the mass, and a is the acceleration. Plug our given values in to find f:
f = ma
f = (0.15 kg) * (12 m/s²) = 1.8 Newtons
Thus, the answer is 1.8 N.

The two major problems with most motor vehicles are that they burn fossil fuels and _____________.
A. Create radioactive waste
B. Create thermal pollution
C. Release chlorofluorocarbons
D. Release greenhouse gases
Answers
Answer:
The two major problems with most motor vehicles are that they burn fossil fuels and. Release greenhouse gases ( D)
The two major problems with most motor vehicles are that they burn fossil fuels and release greenhouse gases. Option (D) is correct answer.
What are the greenhouse gases?The Earth's atmosphere naturally contains these gases or compounds. But humans are also responsible for their release. These gases are essential for capturing the heat from the Sun and gradually raising Earth's temperature. Because of the balance between the energy it absorbs and the energy it reflects back into space, the Earth is habitable for people.
The greenhouse effect is the term used to describe how the greenhouse gases in the atmosphere capture and emit radiation. Without this mechanism, Earth would either be extremely cool or extremely hot, which would make life on the planet impossible.
The greenhouse effect occurs naturally. The release of industrial gases into the atmosphere, the burning of fossil fuels, and other improper human activity are all contributing to an increase in greenhouse gas emissions.
As a result, this has contributed to global warming.

An airplane moves in straight level flight at constant velocity. What is the
net force acting on it if the mass of the plane is 1000 kg and the frictional
drag of the air is 1800 N? *
Answers
Answer:
Net force = 0
Explanation:
We have, an airplane moves in straight level flight at constant velocity.
Mass of the plane is 1000 kg
The frictional force acting of the air is 1800 N.
It is required to find the net force acting on it. We know that net force is given by the product of mass and acceleration. But here the airplane moves with constant speed, it means its acceleration is equal to 0 such that net force is equal to 0.
Traveling in circle requires a net force

Circular motion requires a net inward or "centripetal" force. Without a net centripetal force, an object cannot travel in circular motion. In fact, if the forces are balanced, then an object in motion continues in motion in a straight line at constant speed.

Producing 100 L of ethanol from sugar cane
Producing 200 L of ethanol from sugar beet
Producing 300 L of ethanol from potatoes
Producing 400 L of ethanol from corn
Answers
Answer:
Producing 300 L of ethanol from potatoes
Explanation:
From the diagram, one liter of ethanol production from sugar cane requires 2000 liters of water. Hence, in order to produce 100 L of ethanol from sugar cane, 2000 x 100 = 200,000 L of water.
1000 liters of water is needed to produce 1 liter of ethanol from sugar beet. Hence, 200 x 1000 = 200,000 L of water will be needed to produce 200 liters of ethanol.
1000 liters of water is also required to produce 1 liter of ethanol from potatoes, hence, 300 x 1000 = 300,000 L of water would be required to produce 300 L of ethanol from the same material
About 500 liters of water is required to produce 1 liter of ethanol from corn, hence, 400 x 500 = 200,000 L of water would be needed to produce 400 L of ethanol from corn.
In conclusion, producing 300 L of ethanol from potatoes would require using the most water among all the options.
