what is load distance?​

Answer:

if one bulb burns out the other bulbs will also turn off because they are connected to each other.

Answer:

I think it is 5.6. This is my answer

Answer:

primary voltage/secondary voltage = number of turns on primary coil/number of turns on secondary coil

V1/V2= N1/N2

1.5/5 = 150/N2

0.3 = 150/N2

N2= 150/0.3

N2 = 500

Answer:

The force of gravity = 40 N

Explanation:

Given that,

The mass of a ball, m = 10 kg

The acceleration due to gravity on the surface of Mars, a = 4 m/s²

We need to find the force of gravity of the ball on Mars. The force of gravity on an object is given by :

F = mg

Substitute all the values,

F = 10 kg × 4 m/s²

F = 40 N

Hence, the correct option is (B).

Answer:

B because the earth rotational axis tilt away from the sun.

Answer:

ice is a poor conductor of heat and less dense than water. During winter, ice floats and insulates the water under it. Below the frozen layer, the water remains in its liquid state and does not freeze. Also, oxygen is trapped beneath the layer of ice. This makes it possible for aquatic animals to survive during winter.

Answer:

Electric potential = 0.00054 V

Explanation:

We are given;

Charge; q = 3 pC = 3 × 10^(-12) C

Radius; r = 2 cm = 0.02 m

Formula for the electric potential of this surface will be;

V = kqr

Where;

K is a constant = 9 × 10^(9) N⋅m²/C².

Thus;

V = 9 × 10^(9) × 3 × 10^(-12) × 0.02

V = 0.00054 V

Answer:

a. 25.59 μN b. The magnetic force is directed to the left.

Explanation:

a. The magnitude of the magnetic force

The magnetic force, F on the charge is

F = BqvsinФ where B = magnetic field strength = 1.05 T, q = charge = 6.50 × 10⁻⁶ C and v = speed of charge = 3.75 m/s and Ф = angle between B and v = 90° (since the charge is moving into the page and the magnetic field is directed vertically upwards and they are thus perpendicular to each other)  

So, substituting the values of the variables into the equation, we have

F = BqvsinФ

F = 1.05 T × 6.50 × 10⁻⁶ C × 3.75 m/s × sin90°

F = 25.59 × 10⁻⁶ N

F = 25.59 μN

b. The direction of the magnetic force on the particle

Using Fleming's right-hand rule, the first finger represents the magnetic field and the second finger the direction of the charge(or its velocity), then the thumb represents the direction of the magnetic force on the charge. Since the magnetic field is directed vertically upwards and the particle is directed into the page, the magnetic force which is represented by the thumb is directed to the left.

So, the magnetic force is directed to the left.

Answer:

The Answer is gonna be According D.separate atoms from their electrons

Answer:

A

Explanation:

potential energy is energy due to position

Solution :

Given :

Wavelength of the thin beam of light, λ = 50 μm

Distance of the screen from the slit, D = 3.00 m

Width of the fringe, Δy = ±8.24 mm

Therefore, width of the slit is given by :

[tex]$d=\frac{n \lambda D}{\Delta y}$[/tex]

  [tex]$=\frac{2 \times 50 \times 10^{-9} \times 3}{2 \times 8.24 \times 10^{-3}}$[/tex]

  = 0.000018203 m

  = 0.0182 mm

  = 0.018 mm

The intensity of light is given by :

[tex]$I=I_0\left(\frac{\sin \beta /2}{\beta/ 2}\right)^2$[/tex]   , where [tex]$\beta=\frac{2 \pi D \sin \theta}{\lambda}$[/tex]

[tex]$I=I_0\left(\frac{\sin \frac{\pi d \sin \theta}{\lambda}}{\frac{\pi d \sin \theta}{\lambda}}\right)^2$[/tex]

[tex]$I=I_0\left(\frac{\sin \frac{\pi d y}{D\lambda}}{\frac{\pi d y}{D\lambda}}\right)^2$[/tex]

Now, [tex]$\frac{dy}{D \lambda} = \frac{8.24 \times 10^{-3}\times 0.018 \times 10^{-3}}{4 \times 50\times 10^{-9}\times 4}$[/tex]

               = 0.1854

               ≈ 0.18

[tex]$I=I_0\left(\frac{\sin 0.56}{0.56}\right)^2$[/tex]

  [tex]$=I_0 \times 0.81$[/tex]

  = 2  x0.81

  [tex]$= 1.62 \ W/m^2$[/tex]

Answer:

v = 8.0 m/s

Explanation:

The diagram clearly shows that the string is vibrating in the 5th harmonic. Hence, the length of string in terms o wavelength can be given as:

[tex]L = \frac{5}{2}\lambda\\\\\lambda = \frac{2}{5} L[/tex]

where,

λ = wavelength = ?

L = Length of string = 1 m

Therefore,

[tex]\lambda = \frac{2}{5}(1\ m)\\\\\lambda = 0.4\ m[/tex]

Now, the speed of the wave can be given by the following formula:

[tex]v = f\lambda\\[/tex]

where,

v = speed of wave =?

f = frequency of wave = 20 Hz

Therefore,

[tex]v = (20\ Hz)(0.4\ m)\\v = 8\ m/s\\[/tex]

Hence, the correct answer is:

v = 8.0 m/s

Answer:

Simple harmonic motion is difficult to generate since real processes have irreversibilities, which are omitted in the physical model and represented by physical concept of damping.

Explanation:

It is very difficult to generate simple harmonic motion since real processes have irreversibilities that dissipy the mechanical energy within the system (e.g. air viscosity, friction), meaning that a permanent presence of an external load is needed to counteract such damping effects, in contrast with simple harmonic motion, where motion is self-sustained.

Answer:

K = 9000 J

Explanation:

Given that,

The mass of a boat, m = 2000 kg

The velocity of the boat, v = 3 m/s

We need to find the kinetic energy of the boat. We know that the kinetic energy of an object is given by :

[tex]K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 2000\times 3^2\\\\K=9000\ J[/tex]

So, the required kinetic energy is equal to 9000 J.

A helpful mutation like camoflage would immensely help a species survive and flourish. The reason being the appliances of such a mutation. Camoflage is one of the most apllicable of abilities. It can be used as a defense mechanism, to hide in plain sight, it can be used offensively to avoid being seen while hunting and it can even be used as a form of communication between the species. All of these appliances would greatly benefit the species and would most definitely help it survive and flourish.

Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain.

The Diagram that involves a virtual image is the third diagram  ( C )

The third diagram involves a virtual image because it has its Image on the same side as the object as seen from the description :

The convex lens is centered at 7cm and the object is located at 6cm while the Focal points are 5.5 and 8.5 cm  

and the Image is formed at 4 cm ( on the same side/ half  of the Ruler ).

For a real image to be formed the Image will appear behind the position of the convex lens as seen in the diagram attached below and in Diagrams A and B .
