Explanation:work is force x distance. The wall doesn’t move any distance in A so that’s not work. B involves tasks that do work but I don’t think this is what they’re going for. For a short instance while kicking a ball, your foot is applying a force to the ball which moves a distance before following its own trajectory after contact with your foot. Because the contact has a short duration and isn’t instantaneous, this is work

The path difference is 1.57 × 10⁻⁶ m

Distance is the amount of space between things. From distance, it is the hard to tell if someone's wearing the a vampire costume abd just a chic black outfit.

For constructive interference thai is formation of bright fringe through a diffraction grating is given by:

d sin θ = n λ

here, d is the distance between slits.

θ is the angle of diffraction

n is the order of fringe

and λ is the path difference.

λ = (d sin θ)/ n = (0.60 *10 ⁻³m) (sin 0.30°) ÷ 2 = 1.57 * 10⁻⁶ m

3/7 of the fabric equals 18.

[tex]\large \bold {SOLUTION}[/tex]

To find the solution to your task, we will have to find 3/7 of 42, that is. How much is 3/7 of 42?

So, to find the value we must do the following way, multiply the value of the length of the fabric 42, by the numerator of the fraction 3 and divide by the denominator 7, See:

[tex]\begin{gathered}\Large\begin{array}{c}\tt\dfrac{3}{7}\:in\: 42\\\\ \tt 42\cdot 3=126\\\\ \tt 126\div 7=\boxed{\boxed{\tt 18}}\end{array}\end{gathered}[/tex]

The interior part of Jupiter and Saturn are different from each other due to difference of core and magnetic field.

The interiors of Jupiter and Saturn differ from one another because Jupiter has a larger metallic hydrogen core as compared to Saturn. It has stronger magnetic field as compared to Saturn.

So we can conclude that the interior part of Jupiter and Saturn are different from each other due to difference of core and magnetic field.

Explanation:

1) P = F/A

P = 500 / 0.5

P = 1000N/m²

2) W = mg

W = 50 x 9.8

W = 490

P = F/A

P = 490 / 0.01

P = 49000N/m²

3) P = F/A

For E:

P = 40000 / 0.5

P = 80000N/m²

For W:

P = 600 / 0.0075

P = 80000N/m²

Ultimate tensile strength is the maximum stress that a material can withstand just before fracture.

Stress is defined as the force acting per unit area. It is denoted by Sigma(σ)

When a body is undergoing stretch by applying a pull force, it stretches more and more until it reaches its elastic limit. A point comes when the body no more stretches and breaks or fractures at bottle neck formation. This strength of any material is known as Ultimate breaking Stress or Ultimate tensile strength.

Thus, Ultimate tensile strength is the maximum stress that a material can withstand just before fracture.

The conditions established by forward- and reverse-bias conditions on a P-N junction diode are: For forwarding bias, the current flows easily without opposition, this causes more current to pass, For reversed bias, the current flow is restricted and this causes less amount of current to pass.

A forward bias is a state attained by a diode as a result of its positive terminal that is connected to the positive part of a circuit and its negative terminal connected to the negative part of the circuit.

A reversed bias is a state attained by a diode as a result of its positive terminal that is connected to the negative part of a circuit and its negative terminal connected to the positive part of the circuit.

In conclusion, The conditions established by forward- and reverse-bias conditions on a P-N junction diode are: For forwarding bias, the current flows easily without opposition, which causes more current to pass, For reversed bias, the current flow is restricted and this causes less amount of current to pass.

Periodic

Explanation:

The groups in the periodic table that want to gain electrons are groups; 15, 16 and 17. The members of these groups are mostly nonmetals.

a. The voltmeter reads 0.053 volts

b. The electromotive force, emf of the battery is 0. 106 volts

a. Given the current  = 1. 15A

Voltmeter reads the voltage = V

Resistance could be gotten from the diagram = R

V = IR

To find the resistance from the structure

First, find the resistance in parallel

Resistance in parallel = 1/R1 = 1/R2 + 1/R3 = 1/25 + 1/15 + 1/15 = 0. 17 Ohms

Now, find the resistance in series

Resistance in series = R1 + R2 + R3 = 45 + 0. 17 + 10 = 55. 17 Ohms

Finally, the  resistance in parallel = 1/35 + 1/55. 17 = 0. 028 + 0. 018 = 0. 046 Ohms

Substitute values into the equation

V = IR

V = 1. 15 * 0. 046

V = 0. 053 Volts

b. To find the Emf, use the formula

Emf =  V + Ir

Substitute the values into the formula

Emf = 0. 053 + 1.15 * 0.046

Emf  = 0. 053 + 0. 0529

Emf = 0. 106 volts

Therefore, the voltmeter reads 0.053 volts and the electromotive force of the battery us 0. 106 volts

Answer:

C

Explanation:

you need to be able to see through a colour filter, which means youd need transparent or translucent

Transparent materials passes light and they reflect also. The color filters are made by transparent or translucent materials. Thus option c is correct.

The ability of a material to pass light through it is called transparency. Some transparent materials can reflect the light. For example mirror, glasses etc. The materials which passes light but are not transparent is called translucent materials.

The material which does not pass light inside is called opaque. Wood, plastics etc. are opaque materials. Transparent covers, glasses make their inside visible.

Colour filters are made by transparent or translucent materials. They are used to filter or choose a particular colour from a group of reflected lights.

Color filters are used in spectrometers and other optical devices. They filter the incoming wavelengths to select the desired one. Hence, option c is correct.
