Answer:

1.)When you arrive from school and you smell cookies baking in the kitchen your brain will tell you that you are hungry and that you should go to the kitchen at that point your sense organs like your nose helps you to detect that something is baking(cookies)and your nervous system (brain)will tell you that you are hungry and it will command/direct your brain to go to the kitchen then for you to eat the cookies and drink the milk the digestive system is going go help you to chew,swallow and digest the food which has been taken and when you also run to the kitchen at the beginning your brain will direct your skeletal and muscular system because the skeletons and muscles work hand in hand,and when you finish your meal the body will circulate some nutrients or minerals from the food or snack taken to other parts of the body for energy.

2.)When you sleep the whole body is asleep except the heart which needs to continue circulating blood around the whole system and sometimes the brain may not rest when you are sleeping it may continue to do it's work that's why some people usually sleep walk or sleep talk,it means the brain is not at rest and still doing some things....Thank you for the question I hope it is very useful to you.

A car is rounding a 100-m-radius curve at 25 m/s.What is the minimum possible coefficient of static friction between the tires a
Crazy boy [7]

Answer:

The minimum possible coefficient of static friction between the tires and the ground is 0.64.

Explanation:

if the μ is the coefficient of static friction and R is radius of the curve and v is the speed of the car then, one thing we know is that along the curve, the frictional force, f will be equal to the centripedal force, Fc and this relation is :

Fc = f

m×(v^2)/(R) = μ×m×g

    (v^2)/(R) = g×μ

               μ = (v^2)/(R×g)

                  =  ((25)^2)/((100)×(9.8))

                  = 0.64

Therefore, the minimum possible coefficient of static friction between the tires and the ground is 0.64.

Assume that each cubic centimeter of water has a mass of exactly 1.00 g. what is the mass of one cubic meter of water in kilogra
statuscvo [17]

The mass of one cubic meter of water in kilograms is 1 kg.

This is a conversions case. First, we must determine how many cubic centimeters there are in a cubic meter. We have 1000 of these after conversion.

This essentially indicates that 1000 units of water, each with a volume of one cubic centimeter, would have to combine before we could create a cubic meter of water.

Knowing that one cubic centimeter weighs one gram, 1000 cubic centimeters would weigh 1000 * 1, or 1000g, or one kilogram.

Thus, 1 cubic meters of water will weigh 1 * 1000g = 1000g, or just 1 kg.

A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open to the air at the top. Fr
maw [93]

Answer:

x = 0.081 m.

Explanation:

a) To find how much does the atmospheric pressure cause the spring to compress we need to use the following equation:

F = k*x    (1)

<u>Where</u>:

F: is the force

k: is the spring constant = 3300 N/m

x: is the distance of compression =?

The force can be found as follows:

F = P*A    

<u>Where</u>:

P: is the atmospheric pressure = 101325 Pa

A: is the area of the piston = πr²

r: is the radius = 0.029 m

F = 101325 Pa*\pi*(0.029 m)^{2} = 267.7 N    

Now, from equation (1) we can find x:

x = \frac{F}{k} = \frac{267.7 N}{3300 N/m} = 0.081 m    

Therefore, the atmospheric pressure causes the spring to compress 0.081 m.      

I hope it helps you!

A capacitor is connected to an ac generator. As the generator’s frequency is increased, what happens to the capacitor connected
Bad White [126]

Answer:

Current in the capacitor increases as the frequency of the generator increases

Explanation:

Xc = 1/2πfC = 1/ wC

Since frequency is inversely proportional to reactance of a capacitor,

as the frequency increases, the capacitance decreases and tend towards behaving like a wire with zero resistance as such the generator send high current to the capacitor, the current in the capacitor increases.
