What is the difference between applied force and normal force

Answers

If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person. The normal force is the support force exerted upon an object that is in contact with another stable object.

The slope on a distance-time graph shows a ball moving from 20 m to 40 m in 1 s and from 40 m to 80 m in the next second

Answers

Slope in the first second: 20 m/s

Slope in the next second: 40 m/s

Average slope: 30 m/s

Explanation:

On a distance-time graph, the slope of the curve represents the speed of the object.

In fact, we have:

The distance covered is the change in the y-variable, so $\Delta y$
The time elapsed is the change in the x-variable, so $\Delta x$

Speed is the ratio between distance and time, therefore

$speed = (distance)/(time)=(\Delta y)/(\Delta x)$

which corresponds to the slope of the line.

In this problem, we have a ball moving from 20 m to 40 m in 1 s, so

$distance = 40-20 = 20 m = \Delta y$

$time = 1 s = \Delta x$

So the slope in the first second is

$(\Delta y)/(\Delta x)=(20)/(1)=20 m/s$

In the next second, the ball moves from 40 m to 80 m, so

$distance = 80-40 = 40 m = \Delta y$

$time = 1 s = \Delta x$

So the slope in the next second is

$(\Delta y)/(\Delta x)=(40)/(1)=40 m/s$

While if we consider the overall graph in the 2 seconds, we have

$distance = 80-20 = 60 m = \Delta y$

$time = 2 s = \Delta x$

So the average slope is

$(\Delta y)/(\Delta x)=(60)/(2)=30 m/s$

Hi, I am Nathan, I have a question if you answer correctly I give you more points. what works all the time but never sleeps. that is the question

Answers

Answer: The answer to the question "what works all the time but never sleeps" can vary depending on the context or interpretation. Here are a few possible answers:

Explanation:

1. A machine or technology: Machines such as computers, servers, or automated systems can work continuously without needing sleep. They can perform tasks, process information, or operate machinery 24/7.

2. The human brain: While humans do need sleep for rest and rejuvenation, the brain never stops working. Even during sleep, the brain continues to regulate bodily functions, process information, and even dream.

3. Nature: The natural world is constantly active and functioning. For example, plants continue to photosynthesize, animals continue to move and hunt, and ecosystems continue to interact and evolve, even during the night.

4. Time: Time is always progressing and never stops. The concept of time keeps working, and events and processes occur continuously, regardless of day or night.

These are just a few possible answers. The correct response may depend on the specific context or intended interpretation of the question.

Answer: A man

Explanation:

A man works all day and never gets the chance to sleep.
