Explanation:

The water table maybe defined as the boundary between groundwater saturated spaces and the soil surface. In more explicit terms, the table table is the water level in shallow dug wells. That is when a well is dug, the position of water in the well is called the water table. The water table may rise during the rainy season or areas of high water volume such that the water table meets the the land surface, when this occurs, we have the formation of a spring. This flow is the channeled to streams, rivers or lakes.

Lakes are generally a body of water surrounded by land.

Answer:

A

Explanation:

The moving object will accelerate as long as a net force is applied. If a net force is not applied, the object will continue to move at a constant speed along the same path in curved spacetime (due to gravity). If the net force continues the velocity of the object will continue to increase until nearly reaching the limit (speed of light).

Explanation:

There are a couple of assumptions I had to make here and also a couple of rules based on what I use in my classroom when I teach the Law of Momentum Conservation. First of all, I am going to call the 8kg ball 1 and say that it is moving to the right (and right is positive), and that means that the 3kg ball is ball 2 and say that it is moving to the left (and left is negative). I had to assume that the 2 balls were moving towards each other; hence, the different signs assigned to their movement. I also added in another significant digit since we have only 1 in most of these values and adding in a .0 is not going to change the value of any number. The Law of Momentum Conservation in this particular instance says

[tex][m_1v_1+m_2v_2]_b=[m_1v_1+m_2v_2]_a[/tex] which is the mathematical way of saying that the momentum after the collision is the same as the momentum before it. Filling in:

[tex][(8.0*4.0)+(3.0*-14)]_b=[(8.0*-2.0)+(3.0*v)]_a[/tex] and doing the math here simplifies to

32 - 42 = -16 + 3.0v and

-10 = -16 + 3.0v and

6.0 = 3.0v so

v = 2.0 (and the positive indicates that ball 2 is now moving to the right)

Formula - multiply the energy value by 1e+7

Answer:

1. The tightness of the wire has no effect on the strength of the electromagnet

2. The strength increases with the number of coils

3. The strength of the electromagnet increases with the number of dry cells used

4. The strength of the electromagnet increases with the wideness of the nail but not the length of the nail

Explanation:

The strength of an electromagnet is given by the following relation;

[tex]B = \dfrac{\mu_0 \cdot K \cdot N \cdot I}{L}[/tex]

Where;

B = The magnetic field strength at the center

μ₀ = The magnetic permeability of free space = 4·π × 10⁻⁷ N·A⁻²

N = The number of loops formed by the conductor around the core

I = The current flowing through wire coiled around the nail

K = The magnetic permeability of the nail

L = The length of the coil

Therefore, we have;

1. From the above equation, the tightness of the wire coil around the nail (or the radius, 'R', of the wire) does not does not affect the magnetic field strength

2. The number of coils, 'N', is directly related to the magnetic field strength, 'B', and therefore, increasing the number of turns or coils around the nail, increases the magnetic field strength

3. The current in the circuit is directly related to the magnetic field strength and the number of dry cell used increases the current in the circuit and therefore, can increase the magnetic field strength

4. The size of the nail used in a solenoid and the magnetic field strength are directly related. The wider the nail, the stronger the magnetic field

Answer:

Input power, Ip = 4 Watts

Explanation:

Given the following data;

Power output = 0.8 Watts

Efficiency = 20%

To find the power input of the sunlight onto the solar panel;

Mathematically, the efficiency of a machine is given by the formula;

[tex] Efficiency = \frac {Out-put \; power}{In-put \; power} * 100 [/tex]

Substituting into the formula, we have;

[tex] 20 = \frac {0.8}{Ip} * 100 [/tex]

[tex] 20 = \frac {80}{Ip} [/tex]

Cross-multiplying, we have;

[tex] 20Ip = 80 [/tex]

[tex] Ip = \frac {80}{20} [/tex]

Input power, Ip = 4 Watts

Answer:

The correct answer is 1

Explanation:

A light ray in medium 1 striking a boundary at an angle of theta Subscript 1 Baseline. In medium 2 is a second light ray that is at a larger angle from the normal with angle theta Subscript 2 Baseline. Thus, 1 is the correct option.

Wavelength is the distance between two identical or similar positions it means that it is the distance between crests or trough in the adjacent cycle of the waveform.

Wavelength is denoted by (lambda).

It is measured in meter, or centimeter, or millimeters.

Mathematically,

Wavelength is equal to velocity divided by frequency,

So,

Wavelength (lambda) = Velocity/frequency.

Velocity is in meter per second.

Frequency is in 1/second.

Prism is a transparent object in which if  sunlight is passed then it will be split in a VIBGYOR

where V = vilot, I = indigo, B = blue, G = green, Y = Yellow, O = orange, R = red.

In this series wavelength of red is higher and vilot is smaller and frequency of violet is higher and red is smaller.

Therefore, A light ray in medium 1 striking a boundary at an angle of theta Subscript 1 Baseline. In medium 2 is a second light ray that is at a larger angle from the normal with angle theta Subscript 2 Baseline. Thus, 1 is the correct option.

Answer:

The velocity of an object thrown straight up would be zero at maximum height (just before it starts falling)

Find the initial velocity:

Time = speed/gravitational constant.

Speed = gravitational constant * time

Initial speed = 9.81*3.16

Initial speed = 30.9996

Maximum height:

h = Vinitial^2/ 2g

h = 960.9752/ 2*9.81

h = 48.979368

Answer:

75 N

Explanation:

Given that,

The angle of incline of the ramp is 42°.

The gravitational force of the box, W = 112.1 N

We need to find the force of static friction on the box.

We have that the component of the gravitational force acting along the inclined plane i.e.

[tex]F=W\sin\theta\\\\F=112.1\times \sin(42)\\\\F=75\ N[/tex]

So, the force of static friction is equal to 75 N.

Answer:

F = 6.12 10⁻¹⁵ N,    a = 3.66 10¹² m / s²

Explanation:

The magnetic force is

            F = q v x B

bold letters indicate vectors, the modulus of this expression is

            F = q v B sin θ

as they indicate that the magnetic field is vertical the proton moves horizontally the angle is 90º

suppose that the energy of the proton is totally kinetic

        E = 5.3 MeV (10⁶ 1.6 10⁻¹⁹J / 1 eV) = 8.48 10⁻¹³ J

       E = K = ½ m v²

       v = [tex]\sqrt{2E/m}[/tex][tex]\sqrt{2 \ 8.48 \ 10^{-13} / 1.67 \ 10^{-27}}[/tex]

       v = [tex]\sqrt{2 \ 8.48 \ 10^{-13} / 1.67 \ 10^{-27}}[/tex]

       v = [tex]\sqrt{10.155 \ 10^{14}}[/tex]

       v = 3.19 10⁷ m / s

we calculate

        F = 1.6 10⁻¹⁹  3.19 10⁷  1.2 10⁻³

        F = 6.12 10⁻¹⁵ N

The direction of this out is given by the right hand rule,

thumb in the direction of speed, south to north

fingers extended in the direction of the magnetic field, vertical

the probe points in the direction of the force for a positive charge,  East

To calculate the acceleration we use Newton's second law

        F = ma

        a = F / m

        a = 6.12 10⁻¹⁵ / 1.67 10⁻²⁷

        a = 3.66 10¹² m / s²

the direction of the acceleration is the same as the direction of the force

Explanation:

According to the question, the refractive index of the solid is approximately 2.42.

The refractive index may be defined as the measure of the bending of a light ray when passing from one medium to another. It can also be defined as the ratio of the velocity of a light ray in an empty space to the velocity of light in a substance, n = c/v.

The Refractive index for a medium may be defined as the ratio of the speed of light in a vacuum to the speed of light in that particular medium. It is a pure ratio and hence it does not have a unit.

According to the question,

The speed of light in a solid = 1.24 × 10⁸ m/s.

The refractive index of the solid = ?

The formula for the Refractive index of a medium = (Speed of light in vacuum) / (Speed of light in the medium).

The Speed of light in vacuum = 3 × 10⁸ m/s

[(3 × 10⁸)m/s] ÷ [(1.24×10⁸)m/s]

= (3×10⁸)/(1.24×10⁸)

= 3/1.24

≈ 2.42

Therefore, the refractive index of the solid is approximately 2.42.
