B. Interference is observed with light.
C. Diffraction is observed with light.
D. Unlike sound, light waves don't need a medium to self-propagate
The correct answer to the question is : D) Unlike sound, light waves don't need a medium to self-propagate
EXPLANATION:
Before coming into any conclusion, first we have to understand the nature of sound and light.
A sound wave is a longitudinal wave which requires a medium for its propagation. It can not move in space as space contains no material medium for its propagation.
Light is normally considered as electromagnetic wave which does not require any medium for its propagation. It can travel in space also.
The interference and diffraction can not be explained by the particle nature of light.
Hence, the argument that partially support that light behaves just like a particle is the last statement i.e Unlike sound, light waves do not need a medium to self-propagate.
Answer:
240 miles
Explanation:
in 1 hour = 80 miles
in 3 hours= 80×3 = 240 miles
The strength of electric field depends on the distance from the charge and also the distance between the electric field lines. If the electric field lines are closer to each other, the electric field is strong there. closer the electric field lines to each other in a region, stronger is the electric field. Electric field lines are closest in region Y. hence the electric field is strongest in region Y.
So correct choice is
3) Y
The electric field strength at a given point is determined by how densely the lines on a diagram represent it. The denser the lines, the stronger the field. Therefore, the field strength is strongest where the lines are most closely packed.
The electric field strength at a given point in space is determined by how close the point is to the charge source and the quantity of the charge. In diagrams, the electric field strength is represented by the density of the lines - in other words, the area with the most lines is where the electric field strength is strongest. Based on this principle, if we are to choose between points W, X, Y, and Z, the electric field is strongest at the point where the lines are most densely packed.

A person who is not wearing a seatbelt during a collision will be thrown forward because it maintains forward motion
In Newton's law, it is stated that if the resultant force acting on an object of magnitude is zero, it can be formulated :
then the object tends to defend itself from its state. So for objects in a state of movement, objects tend to move forever. Likewise, for objects in a state of rest, they tend to remain forever. The tendency of objects like this is called inertia
The size of inertia is proportional to mass, the greater the mass of the object, the greater the inertia of the object.
In objects with mass m that move translatively, the object will maintain its linear velocity
When we are in a vehicle that moves forward, then we will still maintain a state of forwarding motion. If our vehicle stops suddenly, then we keep moving forward so we will be pushed forward. From this point, the use of a safety belt serves to hold back our movements so that there are no fatal accidents or collisions.

The person not wearing the seat-belt during a collision may hit the dashboard of the car very hard and this injury might be fatal.
Explanation:
The inertia of a body is a property contained by the body by virtue of its mass. Higher the mass of a body, higher will be the inertia.
According to the Newton's first law of motion i.e. law of Inertia, a body continues to be in its state of rest or motion until and unless an external force acts on the body to change its state.
When a car is moving on a road, the car is in motion and the body of the person in the car is also in the motion along with the car. Now if the car faces any collision, the car will suddenly come to rest.
But the body of the person sitting in the car continues to be in motion as there is no external force acting on the body. If the person is not wearing the seat-belt, the body moves forward and the person may hit the dashboard very hard.
The seat-belt stops the person's body to move ahead and hit the dashboard. So, the seat-belt prevents the person from injury by stopping the body.
Thus, The person not wearing the seat-belt during a collision may hit the dashboard of the car very hard and this injury might be fatal.
