Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.

Cerebellum: is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.

Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.

A coin completes 18 spins in 12 seconds. The centripetal acceleration of the edge of the coin is 2.2 m/s2. The radius of the coi

nlexa [21]

In order to find the radius of the coin, we need to use:

Ac = V^2 r

In which,
Ac = acceleration of the coin = 2.2 m/s^2
V= rotational Speed = (18/12) * 2πr
r= Radius

so,
2.2 = 9(π^2)(r^2) / r
= 9(π^2)r

r = 2.2 / 9(π^2) = 0.02476740044 m . . .or you can rounded it up to 0.025 m

A 9800-N automobile is pushed along a level road by four students who apply a total forward force of 600 N. Neglecting friction,

Alexandra [31]

Answer:

c). $a = 0.60 m/s^2$

Explanation:

As we know that weight of the automobile is given here

so weight = mass times gravity

$W = mg$

$9800 = m(9.8)$

$m = 1000 kg$

now from Newton's law

$F = ma$

$600 = 1000 a$

$a = \frac{600}{1000}$

$a = 0.60 m/s^2$

Why does the Moon not have an atmosphere?

Elena-2011 [213]

Answer: Moon is much smaller in size and has very less mass, when compared to our mighty earth and there is absence of strong magnetic field on the moon which could protect from the incoming solar radiation from the sun. Since there is no magnetic field, it can swipe off any materials that are present there on the moon, diminishing the atmosphere.

This is the reason why moon does not have any atmosphere.

0.5000 kg of water at 35.00 degrees Celsius is cooled, with the removal of 6.300 E4 J of heat. What is the final temperature of

kogti [31]

Answer:

=30.22°C

Explanation:

The enthalpy change made the water to cool.

Enthalpy change = MC∅ where M is the mass of the water, C is the specific heat capacity of water and ∅ the temperature change.

ΔH=MC∅

∅=ΔH/MC

=(6.3×10⁴J)/(0.5kg×4186J/(kg°C))

=30.1

Final temperature = 35.00°C-30.1°C

=4.9°C

You have a suspect on the run in a dry, wooded area; they’ve ditched the gun but are hiding from you. how long do you have to fi

erma4kov [3.2K]

Answer:

C. a few days

Explanation:

The evidence that we will have to investigate is the gunshot residue on the body of the suspect. When a person fires a gun there will be a deposition of material from the components of the chemicals present in the gun. This deposit is called gunshot residue and consists of particles of the propellant or explosive primer.

Experimentation has shown that the period of time that is person will test possible for gunshot residue is 5.27 days.
