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
Answers
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

How do the lights in a series circuit behave when one bulb burns out?
O The rest of the bulbs continue to shine at maximum brightness.
OThe rest of the bulbs continue to shine at a lower brightness.
OThe rest of the bulbs continue to shine at a higher brightness
OThe rest of the bulbs stop shining and shut off.
Answers
Answer:
D. The rest of the bulbs stop shining and shut off.
Explanation:
When one bulb in a series circuit burns, out, the rest of the bulbs stop shining and shut off. Option D is correct.
What is an electric bulb?
An electric bulb is a gadget that uses electricity to create visible light. It is the most popular type of artificial lighting and is necessary for modern society.
The light bulb is connected to a switch in a parallel configuration. The switch is open, which means there will be a lot of resistance and no current will flow via this route.
Across the parallel connection, the battery would create the same potential difference. Because the current would not go via the open switch, it would instead flow through the light bulb, causing it to illuminate.
When one bulb in a series circuit burns, out, the rest of the bulbs stop shining and shut off.
Hence, option D is correct.

how is kinetic energy is stored
Answers
Answer:
Explanation:
Kinetic energy can be stored. For example, it takes work to lift a weight and place it on a shelf or to compress a spring. ... Kinetic energy can also be transferred from one body to another in a collision, which can be elastic or inelastic. One example of an elastic collision would be one billiard ball striking another.

You are given a sample of metal and asked to determine its specific heat. You weight the sample and find that its weight is 28.4n.Ypu carefully add of heat heat energy to he sample and find that its temperature rises.Ehat is the samples specific heat?
Answers
Answer:
The samples specific heat is 14.8 J/kg.K
Explanation:
Given that,
Weight = 28.4 N
Suppose, heat energy [tex]E=1.25\times10^{4}\ J[/tex]
Temperature = 18°C
We need to calculate the samples specific heat
Using formula of specific heat
[tex]Q=mc\Delta T[/tex]
[tex]c=\dfrac{Q}{m\Delta T}[/tex]
Where, m = mass
c = specific heat
[tex]\Delta T[/tex] = temperature
Q = heat
Put the value into the formula
[tex]c=\dfrac{1.25\times10^{4}}{\dfrac{28.4}{9.8}\times(18+273)}[/tex]
[tex]c=14.8\ J/kg. K[/tex]
Hence, The samples specific heat is 14.8 J/kg.K

The eight types of energy are Kinetic Energy, Potential Energy, Thermal Energy, Chemical Energy, Electrical Energy, Radiant Energy, Nuclear Energy, and Sound Energy.
The eight types of energy are:
Kinetic Energy: The energy possessed by an object due to its motion.
Potential Energy: The energy stored in an object based on its position or condition.
Thermal Energy: The energy associated with the motion of particles in a substance. It is related to temperature.
Chemical Energy: The energy stored in the bonds of chemical compounds.
Electrical Energy: The energy associated with the movement of electric charges.
Radiant Energy: The energy carried by electromagnetic waves, such as light or radio waves.
Nuclear Energy: The energy released or absorbed during nuclear reactions or radioactive decay.
Sound Energy: The energy produced by the vibration of objects and transmitted through a medium as sound waves.
These are the commonly recognized types of energy. It's important to note that energy can often be converted from one form to another.

A car accelerates from 1.5 to 18 m/sec in 9.6 seconds. Calculate its acceleration. and the other one is During a race, you speed up from 2.2 m/sec to 4 m/sec in 3.2 seconds. (a) What is your change in speed? ____ m/sec (b) What is your acceleration? ___ m/sec2
Answers
Answer:
(1) The acceleration is 1.72 m/s²
(2) (a) The change in speed is 1.8 m/s
(2) (b) The acceleration is 0.563 m/s²
Explanation:
(1)
Given;
initial velocity, u = 1.5 m/s
final velocity, v = 18 m/s
time of motion, t = 9.6 s
The acceleration is given by;
a = (v - u) / t
a = (18 - 1.5) / 9.6
a = 1.72 m/s²
(2)
Given;
initial speed, u = 2.2 m/s
final speed, v = 4 m/s
time of motion, t = 3.2 s
(a) The change in speed is given by;
Δv = v - u
Δv = 4 m/s - 2.2 m/s
Δv = 1.8 m/s
(b) the acceleration is given by;
a = Δv / t
a = 1.8 / 3.2
a = 0.563 m/s²
