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 statement correctly describes the differences between positive and negative acceleration?
Positive acceleration describes a change in speed: negative acceleration describes no change in speed.
Positive acceleration describes no change in speed; negative acceleration describes a change in speed.
Positive acceleration describes an increase in speed; negative acceleration describes a decrease in speed.
Positive acceleration describes a decrease in speed negative acceleration describes an increase in speed.

Answers

positive accel.=increase in speed

negative accel.= decrease in speed

Answer: positive accel.=increase in speed

negative accel.= decrease in speed

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

Answers

Answer:

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.

How much current must be applied across a 60 Ω light bulb filament in order for it to consume 55 W of power? Unserious answers will be deleted, and reported. (Please show some work)

Answers

Answer: current I = 0.96 Ampere

Explanation:

Given that the

Resistance R = 60 Ω 

Power = 55 W

Power is the product of current and voltage. That is

P = IV ...... (1)

But voltage V = IR. From ohms law.

Substitutes V in equation (1) power is now

P = I^2R

Substitute the above parameters into the formula to get current I

55 = 60 × I^2

Make I^2 the subject of formula

I^2 = 55/60

I^2 = 0.92

I = sqr(0.92)

I = 0.957 A

Therefore, 0.96 A current must be applied.

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.

If a third particle was added to this field with a positive charge, what would it be attracted to?

✔ B

If an uncharged particle was placed between A and B, which way would it move?

✔ neither direction

What is a solution?

A solution is the combination of a solute and a solvent. The solute can be of completely soluble , partially soluble or insoluble in the solvent. The completely dissolving solute forms a homogeneous solution.

A partially soluble or insoluble solution solutes form heterogeneous solutions. The solubility depends on the bond type, mass, pressure, temperature etc.

The solution salt water is formed by dissolving salt in the solvent, water. Similarly, the seltzer water or carbonated water is formed by carbon dioxide dissolved in water solvent.The solute in lemonade is lemon juice and solvent is water.

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.

Length is measure in cm (centimeter)

Mass is measured in g (gram)

Time is measured in s (second).

SI unit: The International System of Units

Length is measure in meter (m)

Mass is measured in kilogram (kg)
