Explanation:

Answer:

The nucleus and all non-valence electrons.

Answer:

1. The weight of the column of water above

2. Due to Gravity

(I would say there are two answers for this question)

Explanation:

1.

The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions. For example, the pressure acting on a dam at the bottom of a reservoir is greater than the pressure acting near the top.

2.

Fluid pressure can be caused by gravity, acceleration, or forces in a closed container. Since a fluid has no definite shape, its pressure applies in all directions. Fluid pressure can also be amplified through hydraulic mechanisms and changes with the velocity of the fluid.

MAGNETIC FORCE...

Answer:

Magnetic force

Explanation:

I'm going to assume you mean

[tex]y = 14t^2 - \dfrac{t^2}{2+5t} - 3[/tex]

Taking the derivative with respect to t on both sides gives

[tex]\dfrac{\mathrm dy}{\mathrm dt} = 2\cdot14t - \dfrac{(2+5t)(2t)-t^2(5)}{(2+5t)^2} - 0 \\\\ \dfrac{\mathrm dy}{\mathrm dt} = \boxed{28t - \dfrac{4t+5t^2}{(2+5t)^2}}[/tex]

You could go on to expand the rational expression into partial fractions. One way to do this:

[tex]\dfrac{5t^2 + 4t}{(2 + 5t)^2} = \dfrac{t(5t+2) + 2t}{(2+5t)^2} \\\\= \dfrac{t}{2+5t} + \dfrac{2t}{(2+5t)^2} \\\\= \dfrac15 \cdot \dfrac{t}{\frac25+t} + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 \cdot \dfrac{t+\frac25-\frac25}{\frac25+t} + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 \left(1 - \dfrac{2}{2+5t}\right) + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 - \dfrac{2}{10+25t}+ \dfrac{2t}{(2+5t)^2}[/tex]

and this would give

[tex]\dfrac{\mathrm dy}{\mathrm dt} = 28t - \dfrac15 + \dfrac2{10+25t} - \dfrac{2t}{(2+5t)^2}[/tex]

Answer:

the average velocity between two points on the path in the limit that the time (and therefore the displacement) between the two points approaches zero.

Explanation:

Over the course of the 4 hours for which farmer Joe's tractor is pulling the heavy plow, the plow is gaining energy by virtue of its displacement --termed the Kinetic energy.

According to the question, Farmer Joe drives the tractor for 4 hours.

However, the tractor is connected to a heavy plow and is used to pull the plow across a rocky field.

The question requires that we determine if the plow is gaining or losing energy.

However, the focus of the question is during the pulling action of the tractor on the plow.

Ultimately, the plow is gaining energy as it is being pulled by the tractor and now has Kinetic energy.

Speed = 342.86 m/s

EXPLANATION

s = v × t/2

600 m = v × 3.5 s/2

600 m × 2 = v × 3.5 s

1200 m = v × 3.5 s

v = 1200 m/3.5 s

The speed of sound in that place  342.86 m/s

The speed of sound is defined as the distance through which a sound wave’s point, such as a compression or a rarefaction, travels per unit of time.

given

distance of cliff= 600 m

time = 3.5 seconds

speed of sound  = ?

distance = speed * time

distance travelled by the sound to come back to the place where the girl was standing will be = 600 * 2 m

speed = distance / time

speed =  600 * 2 m / 3.5 seconds

Drinking water usually helps with gaining hydration cause usually when you get sick you get weak. thats what u think though

Water will help expel toxins from the body that's why it is recommended to sick people to consume more water. Therefore, option (A) is correct.

Proper hydration can be helpful to the skin and mucous cell membranes play a barrier to stop bacteria from entering the body when sick with a virus. Fluid can also help decrease irritation when sneezing, coughing, and even breathing.

Water can help to regulate body temperature, maintain healthy skin and joints, digest food, and help the brain function at its best. Producing requires bodily fluids, like tears and saliva, and removing waste through sweat, and urination.

Dehydration can happen when we lose a high amount of bodily fluids than we’re consuming. This can occur through bodily functions that bring the loss of fluids and electrolytes.

Therefore, it is important to stay hydrated when you are sick.

Explanation:

Hope this helps My Dude.

The acceleration is approximately 4 m/s². Therefore, the correct answer is:

A. 4 m/s²

To determine the acceleration from the graph, we need to look at how the velocity changes over time. Acceleration is defined as the rate of change of velocity with respect to time. In other words, it is the slope of the velocity-time graph.

Looking at the graph, we can see that the velocity changes from 0 m/s to 4 m/s over a time interval of 2 seconds. To calculate the acceleration, we use the formula:

Acceleration (a) = Change in velocity / Change in time

Acceleration (a) = (4 m/s - 0 m/s) / (2 s) = 4 m/s²

So, the acceleration is approximately 4 m/s². Therefore, the correct answer is:

A. 4 m/s²

Answer::27 km per hour West + 17 km per hour North

Explanation:

:27 km per hour West + 17 km per hour North

he or she is right good jod

The velocity for the trip would be 31 km per hour, therefore the correct answer is option B.

An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard. Displacement describes this shift in location.

As given in the problem, on a trip you travel at a constant speed of 50 kilometers per hour North for 1 hour. Then you turn West and travel at a constant speed of 40 kilometers per hour for 2 hours.

The final displacement of the trip = √(50² + 80²)

                                                         = 94.34 kilometers

The velocity of the trip = total displacement of the trip / time period

                                      =94.34 kilometers / 3

                                      = 31 kilometers per hour

Thus, the velocity of the trip would be 31 kilometers per hour.
