Theo is learning about sensation and perception. He is familiar with the five senses. He knows that the human sensory systems send information to the brain through the cranial nerves, but one sensory system sends information to the brain through the spinal nerves as well. Theo will recall which of our sensory systems can also send information to the brain through the spinal nerves? Select one: a. Taste b. Vision c. Hearing d. Touch
Answer:
Touch ( D )
Explanation:
The sense of touch can send information to the brain via the spinal cord and also in some cases the information sent by the sense of touch can as well be processed via the spinal cord
The Touch sensory system is made up of sense receptors which carry the information to be sent to the Central nervous system which the brain and the spinal cord is an essential part

An object with a mass of 5kg has a force of 20N applied to it. What is the resulting acceleration of the object?
Answer:
The answer is 4 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
where
f is the force
m is the mass
From the question
f = 20 N
m = 5 kg
We have
[tex]a = \frac{20}{5} \\ [/tex]
We have the final answer as
4 m/s²Hope this helps you
velocity is derived physical quantity why
Answer:
Velocity is “how much distance you cover in a particular time.” Space and time are fundamental quantities, and meters and seconds are their base units. Velocity is a combination of a space and a time, and therefore its units — “m/s” – are “derived” from the units for space and time
A car starts from rest and accelerates for 2.9 s
with an acceleration of 2 m/s2.
How far does it travel?
Answer in units of m.
Answer:
[tex]a \: = \frac{v - u}{t} [/tex]
2 = v-0/2.9
2× 2.9 = v
v = 5.8 m/s
[tex]v \: = \frac{d}{t} [/tex]
5.8 = d/2.9
5.8×2.9 = d
d = 16.82 m
A racehorse coming out of the gate accelerates from rest to a velocity of 12.0
m/s due west in 2.30 s. What is its average acceleration?
27.6 m/s^2
5.22 m/s^2
-5.22 m/s^2
-27.6 m/s^2
-0.19 m/s^2
O 0.19 m/s^2
Answer:
5.22 m/s²
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 0 m/s
Final velocity (v) = 12 m/s
Time (t) = 2.3 s
Acceleration (a) =.?
Acceleration is defined as the change of velocity with time. Mathematically, it is expressed as:
Acceleration (a) = final velocity (v) – initial velocity (u) / time (t)
a = (v – u) /t
With the above formula, we can obtain the acceleration of the racehorse as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 12 m/s
Time (t) = 2.3 s
Acceleration (a) =.?
a = (v – u) /t
a = (12 – 0) / 2.3
a = 12 /2.3
a = 5.22 m/s²
Therefore, the average acceleration of the racehorse is 5.22 m/s²

difference between fundamental unit and derived unit
Answer:
Fundamental units are the units of the fundamental physical quantities in SI system. They are not formed from other units. There are a total of seven fundamental units such as meter, kilogram, ampere, and second. Derived units are those units that are used for derived quantities.
What is the energy of a 478 kg object that is moving with a speed of 15 m/s
Thermal energy is added to water. Which of the following describes the new state of matter?
A- An exothermic process has caused the phase change.
B- Kinetic energy of particles has decreased.
C- Bonds have been broken that hold particles in place.
D- Particles are attracted to each other and form bonds.
Answer:
Bonds have been broken that held particles in place
Explanation:
Boiling took place with use of thermal energy(heat energy), this will make particles to move faster and apart from each other bcos temperature is increased. Increase in temperature causes increase in kinetic energy
a car slows down from 50.0m/s to 20.0m/s in 60s what is the acceleration
Answer:
-2m/s^2
Explanation:
final velocity = 20m/s
initial velocity = 50 m/s
time taken = 60 s
20-50=30m/s
30/60 = -2
If an object starts accelerating from rest at a rate of 35 m/s2, then how far does it travel during the first second?
How do streams flow?
Answer: When rain falls on the land, it either seeps into the ground or becomes runoff, which flows downhill into rivers and lakes, on its journey towards the seas. As small creeks flow downhill they merge to form larger streams and rivers. Rivers eventually end up flowing into the oceans.

What is meant by the term total internal reflection? What two conditions must be met for total internal reflection to occur?
Answer:
Hello....
Explanation:
Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.
The conditions required for total internal reflection (TIR) to occur are:
1)the light must be travelling from a more dense medium into a less dense medium (ie glass to air)
2)the angle of incidence must be greater than the critical angle.

Which of the following is an accurate description of synaptic pruning?
Answer options:
A) Some connections are lost because critical stages of development were missed.
B) Some connections are lost so others can be strengthened.
C) Some connections are lost because of experimentation with drugs or alcohol.
D) Some connections are lost so that children become less dependent and are less tied to their parents.
Answer:
B) Some connections are lost so others can be strengthened.
Explanation:
Synaptic pruning refers to a natural process that occurs in the brain between childhood and adulthood. Extra synaptic connections are eliminated in order to increase the efficiency of neuronal communications. It is thought to be the brain’s way of removing connections that are no longer needed.

If a 3.1g ring is heated using 10.0 J, its temperature rises 19.7°C. Calculate
the specific heat capacity of the ring.
Answer:
Since 10 J / 4.19 J /cal = 2.39 cal is the heat absorbed by the ring
Q = Cs * m * (T2 - T1) heat absorbed by ring
Cs = 2.39 cal / (3.1 g * 19.7 deg C) = .039 cal / (gm deg C)
10 J / 4.19 J /cal = 2.39 cal is the heat absorbed by the ring, Q = Cs * m * (T2 - T1) heat absorbed by ring. Cs = 2.39 cal / (3.1 g * 19.7 deg C) = .039 cal / (gm deg C).
What is Specific heat capacity?The amount of heat required to raise the temperature per unit mass is known as specific heat capacity. The heat in Joules required to increase the temperature of 1 gram of sample by 1 Kelvin or degree Celsius is typically stated.
Water is an excellent temperature regulator because it has a very high specific heat capacity.
The amount of heat in joules needed to raise 1 gram of a substance by 1 Kelvin is known as the specific heat capacity (symbol: c). It could also be written as J/kgK. Molar heat capacity, measured in J/mol K, and volumetric heat capacity, measured in J/m3 K, are comparable values.
Therefore, 10 J / 4.19 J /cal = 2.39 cal is the heat absorbed by the ring, Q = Cs * m * (T2 - T1) heat absorbed by ring. Cs = 2.39 cal / (3.1 g * 19.7 deg C) = .039 cal / (gm deg C).

How can Newton's third law describe the forces affecting a rocket as it
descends to Earth's surface?
A. The rocket can move downward because the forces acting on it
are unbalanced.
B. The maximum amount of force the rocket engines can provide
determines how much mass the rocket can lift.
C. The rocket pushes through the air with a force equal to that of
Earth's gravity pulling on the rocket.
D. The force the rocket exerts on the air is in the direction opposite to
the force that the air exerts on the rocket.
Answer:
its D
Explanation:

The force the rocket exerts on the air is in the direction opposite to
the force that the air exerts on the rocket.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Every action has an equal and opposite response, according to Newton's Third Law. Burning fuel in a rocket causes a push that propels the rocket forward from the front. As a result, the exhaust gas is pushed in the opposite direction and equally.
The force the rocket exerts on the air is in the direction opposite to
the force that the air exerts on the rocket.
