Each of 116 identical blocks sitting on a frictionless surface is connected to the next block by a massless string. The first block is pulled with a force of 116 N. What is the tension in the string connecting block 100 to block 99? What is the tension in the string connecting block 50 to block 51?

Answers

Blocks 50 and 51 are connected by a string with a 50 N tension.

The definition of tension

The force transmitted through a rope, string, or wire when pulled by forces acting from opposite sides is referred to as tension. The tension force is applied along the entire length of the wire and exerts an equal amount of force on the bodies at each end. Every physical object that comes into contact with another one applies some sort of force.

A massless string links each of the 116 identical blocks that are perched on a surface without friction to the block in front of it. 116 N of force is used to pull the first block.

Considering that each block weighs 1 kg

The force's equation is given as

F = ma

a = F/M

a = 116/116

a = 1m/s².

Now, from block 100 to block 99,

F = ma

F = 1×1

F = 1 N

At this time, the blocks 50 and 51. 50 blocks are behind the 51st block, so,

m = 50 kg

a = 1m/s²

F = 50×1

F = 50N.

Light is refracted and spread out by a ____. Question 14 options: concave lens convex mirror concave mirror convex lens

Answers

Light is refracted and spread out by a concave lens.

What is refraction?

Refraction refers to a phenomenon which describes a change (bend) in the path taken by light when it comes in contact with surfaces between different transparent materials. The refraction of light is inversely proportional to its wavelength.

When parallel rays of light enter into a concave lens, the light waves refract outward (spread out). The light rays refract twice: first when entering the lens and second when leaving the lens. Only the light rays passing through the center of the lens remain straight.

Answers

The resultant force exerted by the magnets on the charge will be zero.

According to the Lorentz force equation, only moving charges experience magnetic forces. Therefore, a charge at rest experiences no force and does not move. Only moving charges can experience a magnetic force, so the force on a stationary charge is zero. The magnetic force is always perpendicular to the velocity of the charged particles, so the particles move in a circular motion.

Answers

Kinetic energy is the energy that the pendulum have when it is hanging straight down and at the lowest point pendulum is the potential and kinetic energy is maximum.

A simple pendulum consists of a small mass suspended on an approximately massless, non-stretchable string. It is free to oscillate from side to side. The forces acting on the mass are the force of gravity and the tension in the string.

The tension cancels out the component of mg that lies along the string; this keeps the object from accelerating in the direction of the string, and thus keeps the string's length constant.

The net force is simply the remaining component of mg, which is pointed perpendicular to the string and is equal to Fnet=-mgsinФ

The pendulum only has gravitational potential energy, as gravity is the only force that does any work. The total energy of the pendulum is the potential energy at the maximum displacement, when the displacement is equal to the amplitude is 1/2mgLA^2.

❧ What are the uses of mirrors and other reflecting surfaces?

Answers

Mirrors and other reflecting surfaces can be used in the following way; used in kaleidoscopes, periscopes which are widely used in submarines,  used in headlights to reflect parallel rays of light in a straight line etc.

What is a mirror?

A mirror is a reflecting surface that reflects light almost totally and does not allow it to refract, producing a clear image. It produces either real or virtual images.

Types of Mirrors

Plane Mirror - These are made by putting some reflective substance like silver nitrate onto a piece of glass. When we place an object in front of a plane mirror, an image is formed by reflection.

Concave - It is a mirror that is bent inside at its center. The law of reflection also holds for the concave mirror, but the angle of incidence is not equal to the angle of reflection. A concave mirror can produce a real or virtual image in front of it at its point of focus.

Convex -  is also called a diverging mirror. The reflective surface of the convex mirror is slightly extended towards the source of light. A convex mirror can reflect all rays falling on it in the outward direction. It produces a virtual image. The size of the image produced by this kind of mirror is smaller than the actual object.

Uses of mirrorsA plane mirror is used in kaleidoscopes. Plane mirrors are also used in periscopes which are widely used in submarines.They are used in headlights to reflect parallel rays of light in a straight line. Convex mirrors are used as side mirrors in vehicles because they form erect images and cover wider views. Plane mirrors are also used in flashlights and torches to give the source light a straight path. They are also used in microscopes to reflect the beam of light. Plane mirrors are used in solar cookers because they excellently reflect solar rays.

You may have observed that the pitch of a siren decreases sharply as it passes you at a high rate of speed. When the pitch is higher, the siren first approaches you. The siren is moving away from you and becomes quieter once it has passed you. The Doppler effect is manifested in this way.

The region that the sound waves cover grows as one gets farther from the source of the sound. The intensity and loudness of the sound are reduced because the same quantity of energy is dispersed over a larger region.

Thus, a bar magnet is quite different from an electromagnet, and its magnetism is due to electron spins, not electric currents. Spins of electrons in neighboring atoms are aligned by the exchange interaction, which is a consequence of the Pauli exclusion principle.

Answers

The maximum energy stored in the circuit Q = 3.44 × [tex]10^{-8}[/tex]

Umax = L[tex]I^{2}[/tex]max/2  = [tex]Q^{2}[/tex]/2C

L[tex]I^{2}[/tex] /2 = [tex]Q^{2}[/tex]/2C

[tex]Q^{2}[/tex] = LC[tex]I^{2}[/tex]

Q = 0.780 ([tex]\sqrt{81 X 10 ^{-3} }[/tex])([tex]\sqrt{1.55 X 10^{-9} }[/tex])

The maximum energy stored in the circuit Q = 3.44 × [tex]10^{-8}[/tex]

Energy is the quantitative attribute that is transferred to a body or to a physical system. It is recognized in the execution of work as well as in the form of heat and light (from the Ancient Greek: v, enérgeia, "activity"). Energy can be transformed in form but cannot be created or destroyed, according to the rule of conservation of energy. The joule is the SI's (International System of Units) unit of measurement for energy.

A moving object's kinetic energy, a potential energy stored by an object (for instance because of its position in a field), the elastic energy contained in a solid object, chemical energy linked to chemical reactions, radiant energy carried by electromagnetic radiation, and internal energy contained within a thermodynamic system are examples of common forms of energy. Energy is continuously taken in and released by all living things.

Any item that has mass when it is motionless (referred to as rest mass) also has an equivalent amount of energy, known as rest energy. As a result, any additional energy (of any type) that the object acquires above that rest energy will increase the object's total mass as well as its total energy.
