The speed, wavelength, and frequency of a wave are related by a scientific theory.
True or False?
Answers
It is a false statement to say that speed, wavelength, and frequency are related by a scientific theory.
What is speed?This is defined as the distance travelled per unit time.
Speed = distance / time
What is frequency?This is defined as the number of oscillations made in one second. It is expressed as
Frequency (f) = 1 / period (T)
f = 1 / T
What is wavelength?This is simply defined as the distance between two successive crests or trough
Relationships between frequency, wavelength and velocityThe velocity, frequency and wavelength of a wave are related according to the following equation
Velocity (v) = wavelength (λ) × frequency (f)
v = λf
From the above definitions, we can see that the speed, wavelength and frequency are only related by mathematical equation and not by scientific theory.

What is the reason for sprinkling iron filings around these two magnets?
Answers
The reason for sprinkling iron filings around these two magnets is to make it possible to see where the magnetic field lines are, therefore the correct option is C.
What is a magnetic field?A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted. The SI unit of the magnetic field is tesla.
The behavior of the magnetic material around the magnetic field is such that they align themselves in accordance with the path of the magnetic field lines, therefore, these iron filings are very handy for knowing the magnetic field line's path ad the poles of a bar magnet as well.
The reason for sprinkling iron filings around these two magnets is to make it possible to see where the magnetic field lines are, therefore the correct option is C.

Answers
Answer:
Friction
Explanation:
There are some forces that will work against the motion in every situation, the force of air resistance is often observed to oppose the motion of an object, Frictional Force, Gravitational Force, Normal Force, Magnetic Force, and Tension Force.
What is Force?Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.
Newton is a unit of force used by physicists that is part of the International System (SI). The force required to move a body weighing one kilogram one meter per second is known as a newton.
Therefore, the force of air resistance is often observed to oppose the motion of an object, Frictional Force, Gravitational Force, Normal Force, Magnetic Force, and Tension Force.

Why do you think a compass needle always points north? (Write your initial ideas. It is OK if you are unsure about them.)
Answers
Answer:
A compass points north because magnets have two poles (north and south pole). The north pole of one magnet is attracted to the south pole of another magnet.
Explanation:
Hope this makes sense! :D
The geographic north of Earth is close to its magnetic south pole. Because they are attracted to each other, the Earth's south magnetic pole is where the north pole of a compass points. That's why, a compass needle always points north.
What is compass?A compass is a tool used for geographic orientation and navigation that displays the cardinal directions. It typically consists of a magnetized needle or other component that may pivot to line up with magnetic north, like a compass card or compass rose.
Angles are frequently displayed on compasses as degrees: north is 0°, east is 90°, south is 180°, and west is 270°. The compass may display azimuths or bearings, which are often expressed in degrees, thanks to these numbers. True north can be determined by knowing the local difference between magnetic north and true north, and vice versa.

What is an inelastic collision?
Answers
Answer:
An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities inelastic collisions.
Explanation:
Suppose two similar trolleys are traveling toward each other with equal speed. They collide, bouncing off each other with no loss in speed. This collision is perfectly elastic because no energy has been lost. In reality, examples of perfectly elastic collisions are not part of our everyday experience. Some collisions between atoms in gases are examples of perfectly elastic collisions. However, there are some examples of collisions in mechanics where the energy lost can be negligible. These collisions can be considered elastic, even though they are not perfectly elastic. Collisions of rigid billiard balls or the balls in Newton's cradle are two such examples.
