The aqueous humor in a person’s eye exerts a force of 0.295 n on the 1.15-cm2 area of the cornea pressure is this in mm Hg P = 2565.2173 N/m².

Pressure is defined as the normal force F per unit area A over which the force is applied or

P = F / A

Where :

P is the pressure acting on the cornea .

F if the force acting on the cornea .

A is the area of the cornea .

Givens : F = 0.3 N and A = 0.00011 m

Plugging known information to get :

P = F / A

P = 0.295 / 0.000115

P = 2565.2173

P =2565.2173 N/m²

Thomson could not observe any deflection of the beam due to gravitation.

Cathode ray refers to the beam of electrons that moves from the negatively charged cathode to the positive anode at the other end of the pipe.

J. J. Thomson demonstrated that the identical beam deflections produced tubes with cathodes composed of varied materials and containing a range of gases prior to evacuation.

The gravitational force is approximately 10⁴⁰.

The movement of the light beam shouldn't be impacted because it is 10²⁸ times weaker than the electric force.

Thomson was unable to detect any gravitational beam deflection.

Thus, Thomson could not observe any deflection of the beam due to gravitation.

The radiation pressure directed at normal incidence onto a perfectly reflecting sheet is 2.71 × 10⁻⁷ Pa

Given that a linearly polarized microwave of wavelength 1.50cm is directed along the positive x axis and the electric field vector has a maximum value of 175V/m and vibrates in the x y plane.

Also, assuming the magnetic field component of the wave can be written in the form B=Bmax sin (k x-Ω t) give values for (f) If this wave were directed at normal incidence onto a perfectly reflecting sheet, we desire to find the radiation pressure.

The radiation pressure for total reflection is given by P = 2I/c where

So, P = 2I/c

P = 2E²/2μ₀c ÷ c

P = E²/μ₀c²

Substituting the values of the variables intot he equation, we have

P = E²/μ₀c²

P = (175 V/m)²/[4π × 10⁻⁷ T/m × (3 × 10⁸ m/s)²]

P = 30625 V²/m²/[4π × 10⁻⁷ T/m × 9 × 10¹⁶ m²/s²]

P = 30625 V²/m²/[36π × 10⁹ Tm/s²]

P = 30625 V²/m²/113.097 × 10⁹ Tm/s²

P = 270.78 × 10⁻⁹ Pa

P = 2.7078 × 10⁻⁷ Pa

P ≅ 2.71 × 10⁻⁷ Pa

So, the radiation pressure directed at normal incidence onto a perfectly reflecting sheet is 2.71 × 10⁻⁷ Pa

Answer:

You should weigh about 16 pounds.

Explanation:

To find this, you need to find your weight and divide it by 6 to find your weight on the moon.

Answer:

Ahmed did more work in lifting the weight than Omar.

Explanation:

Work done can be determined as the product of a force and the distance moved in the direction of the force.

Work done = F x s

In the given question, since the weight is lifted through a height, then the work done equals potential energy.

i.e Work done = Potential energy

                       = mgh

But,

Force = weight = mg

So that,

Work done = Fh

where F is the weight and h is the height.

i. Work done by Omar = Fh

                            = 200 x 2.0

                            = 400

Work done by Omar is 400 Nm.

ii. Work done by Ahmed = Fh

                                     = 200 x 2.1

                                     = 420

Work done by Ahmed is 420 Nm.

Thus, Ahmed did more work in lifting the weight than Omar.

Although not always practical, Ampere's law is true for all closed channels around a conductor. The integral can be calculated along many different paths, although it is difficult to do so. Think about a path that is circular but not coaxial with a long, straight wire that carries current. If the current in a conductor has enough symmetry to allow the line integral to be reduced to the size of B times an integral, Ampere's law can be used to calculate B.

The current in the load will be 10 A.

given,

resistance of the load (R) = 6.5Ω

voltage in the load (V) = 120V

Back emf in the load (E)= 108V

now to measure current we will use the formula

current (I)= {voltage (V)-Back emf (E)}/resistance(R)

now as the speed is halved so will the back electro motive force will be halved.

i.e.

back  electro motive force will be =  108V/2

=54V

Answer:

2.64 m/s

Explanation:

Given that a 600 kilogram great "yellow" shark swimming to the right at a speed of 3 meters traveled each second as it tries to get lunch. An unsuspecting 100 kilogram blue fin tuna is minding its own business swimming to the left at a speed of 0.5 meters traveled each second. GULP! After the great "yellow" shark "collides" with the blue fin tuna

Momentum = MV

Momentum of the yellow shark before collision = 600 × 3 = 1800 kgm/s

Momentum of the tun final before collision = 100 × 0.5 = 50 kgm/s

Total momentum before collision = 1800 + 50 = 1850 kgm/s

Let's assume that they move together after collision. Then,

1850 = ( 600 + 100 ) V

1850 = 700V

V = 1850 / 700

V = 2.64285 m/s

Therefore, the momentum of the shark after collision is 2.64 m/ s approximately

It is proved that the speed of the light measured in the laboratory frame is , u =c/n(1+ nv/c)/(1+ v/nc) .

Given ,

The motion of a transparent medium influences the speed of light .

The water moves with speed v in a horizontal pipe .

Assume that the light travels in the same direction as the water moves .

The speed of the light with respect to the water is c/n

Where n = 1.33 is the refractive index of water .

Let us assume ,

u' be the speed of light in water , in the frame moving with the water .

u' is related to the refractive index of water ,n as :

u'=c/n

where , c is the speed of light .

let , u be the speed of light in water in the lab frame .

Now , u and u' are related as : u = (u'+ v )/(1+ u'v/c^2)

Here v is the speed of water in the horizontal pipe .

we know the value of u' , so by substituting the value , we will get ,

u= (c/n+ v)/(1+cv/nc^2)

u= c/n(1+ nv/c)/(1+v/nc)

Hence , it is proved that the speed of the light measured in the laboratory frame is , u =c/n(1+ nv/c)/(1+ v/nc) .

Answer:

You need a motor and a battery

Explanation:

The currents through 4 ohm, 2 ohm and 5 ohm are 0.42 amp, 0.15 amp and 0.26 amp respectively.

Kirchhoff's Current Law states that no charge is lost and that the total current flowing into a junction or node equals the charge leaving it.

Kirchhoff's Voltage Law states that for any closed network, the voltage around a loop is equal to the total of all voltage drops in that loop and is equal to zero.

Let the current through 4 ohm is I₁.

the current through 2 ohm is I₂.

Applying Kirchhoff's Current Law, current through 5 ohm is I = I₁ + I₂.

Applying Kirchhoff's Voltage Law in two loops we get:

4 I₁ + 5(I₁+I₂) = 3

2I₂ + 5(I₁+I₂) = 1

Hence, I₁ = 0.42 amp

I₂ = - 0.15 amp

I₃ = 0.26 amp

Hence, the currents through 4 ohm, 2 ohm and 5 ohm are 0.42 amp, 0.15 amp and 0.26 amp respectively.

Therefore, even at a great distance, the intensity of the reflected beam is unaffected.

Parabolic In search lights, concave mirrors with sizable apertures are utilized. For searching items in search light, we require a powerful parallel beam of light. The reflected rays from an object placed at a concave mirror's focus are parallel to one another and likewise parallel to the main axis.

Explanation:

Newton's second law states that the force exerted on an object is equal to the rate of change of its momentum.

Let F represent force and p momentum and p = mv where m = mass and v = velocity
