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 m/s2

Explanation:

Given: 200 N, 50 kg

To find: a

Formula: [tex]A = \frac{f}{m}[/tex]

Solution: To find a, divide the force by the weight

A = F ÷ m

=  200 ÷  50

= 4 m/s²

Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

Answer:

[tex]\frac{n}{t} = 30\ photons/s[/tex]

Explanation:

The radiated power can be given in terms of the wavelength as follows:

[tex]Rasiated\ Power = \frac{nE}{t} = \frac{nhc}{\lambda t}[/tex]

where,

Radiated Power = 1.2 x 10⁻¹⁷ W

n = no. of photons = ?

h = plank's constant = 6.625 x 10⁻³⁴ J.s

c = speed of light = 3 x 10⁸ m/s

λ = wavelength = 500 nm = 5 x 10⁻⁷ m

t = time

Therefore,

[tex]1.2\ x\ 10^{-17}\ W = \frac{n(6.625\ x\ 10^{-34}\ J.s)(3\ x\ 10^8\ m/s)}{(5\ x\ 10^{-7}\ m)(t) }\\\\\frac{n}{t} = \frac{1.2\ x\ 10^{-17}\ W}{3.975\ x\ 10^{-19}\ J}\\\\\frac{n}{t} = 30\ photons/s[/tex]

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:

   q = 224 mm,   h ’= - 98 mm, real imagen

Explanation:

For this exercise let's use the constructor equation

        [tex]\frac{1}{f} = \frac{1}{p} + \frac{1}{q}[/tex]

where f is the focal length, p and q are the distance to the object and the image respectively.

In a mirror the focal length is

        f = R / 2

indicate us radius of curvature is equal to the diameter of the eye

       R = 3,50  10² mm

       f = 3.50 10² /2 = 1.75 10² mm

they also say that the distance to the object is p = 0.800 10³ mm

        1 / q = 1 / f - 1 / p

        1 / q = 1 / 175 - 1 /800

        1 / q = 0.004464

         q = 224 mm

to calculate the size let's use the magnification ratio

          m = [tex]\frac{h'}{h} = - \frac{q}{p}[/tex]

          h '= [tex]- \frac{q}{p} \ h[/tex]

          h ’= - 224 350 / 800

          h ’= - 98 mm

in concave mirrors the image is real.

Answer:

No the statement is incorrect.

Explanation:

Mathematically, force F experience of a charge particle of magnitude q in an uniform electric field E is given as

F = E/q

In uniform electric field is where the intensity of electric field remains same throughout. However, from the above equation it is clear that force experience by the charge particle also depends upon the magnitude of charge particle as well. So, with change in charge particles the force experienced by it also changes.

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:

constructive interference.

Explanation:

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.

Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m.

In this scenario, an experiment is conducted by Pierce in which waves collide in a way that the energy increases. Thus, this is an example of constructive interference i.e constructive interference has occurred.

An interference occurs when two pair of waves such as sound and light waves pass through each other i.e crossing each other's path while traveling through the same medium or space.

Answer:

C- How much water it displaces

Explanation:

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:

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:

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°.

Answer:

F = 2.68 x 10²³ N

Explanation:

The force between lo and Jupiter is given by Newton's Gravitational Formula:

[tex]F = \frac{Gm_1m_2}{r^2} \\[/tex]

where,

F = Force = ?

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²
