How does the law of conservation of energy apply to machines?Machines create energy from scratch.

Machines consume energy until no energy remains.

Energy transferred to a machine equals energy transferred from it.

Engineers break the law of conservation of energy by using ma

Answers

Answer 1
Answer: Energy transferred to a machine equals energy transferred from it. It is because according to conservation of energy we can't create or destroy energy so, energy remains constant however, their form can be change by machine's

In short, Your Answer would be Option C

What does work depend on in scientific terms?

As the speed of a fluid increases, ____.a. the pressure decreases
c. the force decreases
b. the pressure increases
d. the volume decreases

Answers

The correct answer for the question that is being presented above is this one: "a. the pressure decreases." As the speed of a fluid increases, the pressure decreases." The relationship of the speed and the pressure is inversely proportional. As the pressure increases, the speed decreases.

I think the answer is A.

All of the following are true of models except

Answers

I did this.
If your answers look like this... 
a. models have the ability to communicate 
b. models have the ability to correctly predict all outcomes 
c. model have the ability to test predictions
d. models have the ability to save time 
Then it's D

Final answer:

Models are representations that help us understand and analyze real-life situations, but they may have limitations or assumptions that make some statements not universally true.

Explanation:

Models are representations of real-life situations or things that help us understand and analyze them better. However, the statement, 'all of the following are true of models except,' implies that there are some characteristics that do not apply to models. Different models may have different purposes, limitations, or assumptions that may make some statements not universally true. For example, while models can provide insights and predictions, they cannot capture the full complexity of the real world or account for all variables. Models are valuable tools in various fields and disciplines, including social studies, as they help us simplify, analyze, and communicate complex phenomena and processes.

Which statement describes dynamic equilibrium? A. The forces on an object in motion are balanced. B. An object is accelerating due to forces acting on it. C. The forces on an object are unbalanced. D. The forces on a stationary object are balanced.

Answers

Answer: A. The forces on an object in motion are balanced.

Explanation:

The dynamic equilibrium is defined as the phase when an object moves at a constant velocity such that all forces on the object are balanced.

Simple case of dynamic equilibrium: A horizontal force is applied to an object making it run with a constant velocity across a surface.

Hence, the statement describes dynamic equilibrium is " The forces on an object in motion are balanced. "

So, the correct option is "A".

Which of the following statements about iron filings placed upon glass resting on top of a bar magnet is false? A. The density of the filings will match the intensity of the magnetic field. ield outlined by the filings will be from the north pole of the magnet to the south pole. C. The filings will be clustered more densely where the field is weakest. D. The filings will sit on the glass on curved paths between the north and south poles.

Answers

The correct answer for the question that is being presented above is this one: " C. The filings will be clustered more densely where the field is weakest." The statement about iron filings placed upon glass resting on top of a bar magnet that is false is that the filings will be clustered more densely where the field is weakest. 

Correct answer choice is:

C. The filings will be clustered more densely where the field is weakest.

Explanation:

The closer mutually the field lines will be the more powerful the field would be present. The field is really powerful in the axis of the magnet, though as they are frequently accommodated in the magnet itself, the field is quite weak in the air close to the axis. As the field lines make rings, they have to penetrate in one spot and drop at different, the two poles must be extremely close mutually indeed in the air, and the field is consequently stronger. These points are the North and the south poles.

What is the metric unit of force? kg kg/cm^3 kg/cm^2 N

Answers

force is found by multiplying mass (kg) and acceleration (m/s^2), so the metric unit of force is kg*m/s^2 or N (newtons)

A spring is stretched 0.75 m by using a force of 30 N. What is the spring constant

Answers

Hi there!

40 N/m

We can use Hooke's Law:

F = kx or F = -kx

F = force (N)

k = Spring constant (N/m)

x = displacement (m)

We are given the force and displacement, so:

F/x = k

30/0.75 = 40 N/m
