Explanation:

The distribution of touch receptors in human skin is not consistent over the body. In humans, touch receptors are less dense in skin covered with any type of hair, such as the arms, legs, torso, and face.  If two points are felt as two separate points, each is in the receptive field of two separate sensory receptors.

Answer:

A. 4 m³

B. 1 m³

Explanation:

A. Determination of the new volume.

Initial Volume (V₁) = 2 m³

Initial temperature (T₁) = 27 °C + 273 = 300 K

Final temperature (T₂) = 327 °C + 273 = 600 K

Final volume (V₂) =?

V₁ / T₁ = V₂ / T₂

2 / 300 = V₂ / 600

Cross multiply

300 × V₂ = 2 × 600

300 × V₂ = 1200

Divide both side by 300

V₂ = 1200 / 300

V₂ = 4 m³

B. Determination of the new volume.

Initial Volume (V₁) = 2 m³

Initial temperature (T₁) = 27 °C + 273 = 300 K

Final temperature (T₂) = –123 °C + 273 = 150 K

Final volume (V₂) =?

V₁ / T₁ = V₂ / T₂

2 / 300 = V₂ / 150

Cross multiply

300 × V₂ = 2 × 150

300 × V₂ = 300

Divide both side by 300

V₂ = 300 / 300

V₂ = 1 m³

Answer:

D. Current with not flow through a wire if the magnet is outside the coil.

Explanation:

have a good day

The movement of the electrons caused by the magnetic field's pull on them causes an electric current to flow through a wire coil when it is passed over a stationary bar magnet, hence option D is correct.

It is possible to think of the magnetic field as a scalar object with a single magnitude in space.

The magnetic field is described as a field around a magnet that exerts a magnetic force on electrically charged particles present in the magnetic field. Teslas are a unit of measurement for the magnetic field.

Magnetic fields, or vector fields, have an impact on electric currents, electric charges, and magnetic materials. In a magnetic field, a moving charge experiences an external force that is perpendicular to the magnetic field and has its own velocity.

Therefore, current will not flow through a wire if the magnet is outside the coil is a false statement.

Answer:

360J

Explanation:

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

Answer:

32.1176°

Explanation:

In the picture above, I hope that it's a correct answer.

From the Snell's law, the angle of refraction will be 32.117°.

The Snell's law states that the ratio of sine of angle of incidence and angle of refraction is equal to the ratio of refractive index of second medium to the first medium.

sin i/sin r = n(water) / n(air)

r =sin⁻¹ (sin 45 x 1/ 1.33)

r =32.117°

The angle of refraction is 32.117°.

I'm not sure how to use it using the Series, but it would be the plastic comb

Explanation:

In the winter, it's likely to be cold and the glass would absorb that energy, also making it cold. in order to be able to hold it, you would need something warm, thus making the plastic one the better option as it is less likely to absorb the cold energy

Answer:

heat is a measure of how energy flows from hot to Cold object. It means the same thing as temperature

Heat is a measure of how much energy flows from hotter objects to cold objects. It flow the same thing as temperature.

Temperature is a physical quantity which measures hotness and coldness of a body. Temperature measures the degree of vibration of molecule in a body. Temperature is measured in centigrade (°C), Fahrenheit (°F) and Kelvin (K) in which Kelvin (K) is a SI unit of temperature. Absolute scale of temperature means Kelvin scale of temperature. relation between Kelvin(K) and centigrade (°C), °C= K - 273.15 from equation, 273.15 K means 0 °C, which is freezing point of water (ice). when we give temperature to the body, its molecule or atom absorbs thermal energy and vibrate about their mean position. Amplitude of vibration get increases as we go on increasing temperature and for higher temperature force of attraction between molecules gets weaker. Hence for higher temperature, due to weaken the force of attraction between molecule, solid goes into liquid state. and further increase in temperature liquid goes into gaseous state.

Answer:

Electricity comes from power generation plants (some homes have solar cells which produce most of the electricity

Older plants use coal and gas as fuels for power generation (if you see a train go thru with 100 or so cars loaded with coal, that may be from Wyoming and going to a coal fired plant)

Wind farms are becoming more plentiful and produce some portion of the electricity generated

Solar cell farms are also used to produce a small portion of electricity

Heat pumps can use geothermal sources (heat from the ground)

Wave motion of water can also be used to produce electricity
