Is it possible for a nonzero net force to act on an object without the object's speed changing?
Yes, it is possible for a nonzero net force to act on an object without changing its speed. This can happen if the force is acting perpendicular to the direction of motion, resulting in a change in direction but not speed (as in circular motion).
When there is no refraction of light and why does it happen?
There will be refraction when light passes from one substance to the other (for example, from air to water), when the two substances have different indices of refraction, and when light passes the surface at an angle. In other cases, there is no refraction.
What will happen to the angle of refraction if the angle of incidence is made smaller for light passing from rarer to denser medium and how?
If the angle of incidence is made smaller for light passing from a rarer to a denser medium, the angle of refraction will also decrease. This is because of the law of refraction, which states that light bends towards the normal when moving from a rarer medium to a denser medium. Therefore, as the angle of incidence decreases, the angle of refraction will also decrease.
What will happen if the biosphere stoped changing?
it will probley end life as we know it
Could cellular respiration happen without without phoyosynthesis?
could cellular respiration happen without photosynthesis explain your reasoning
Can reflection of light happen without changing the direction of light?
No, reflection means that the direction of light is changed.

How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
What are three things that can happen to light when it hits a new medium?
Reflection: Light can bounce off the surface of a new medium, changing direction. Refraction: Light can bend or change direction as it passes through a new medium, due to a change in its speed or wavelength. Absorption: Light can be absorbed by a new medium, converting its energy into other forms such as heat.
What is a refraction why does it happen?
Refraction is the bending of light as it travels from one medium to another with a different density, such as from air to water. This change in speed causes the light waves to change direction. Refraction happens because light travels at different speeds in different mediums, leading to a change in the angle of the light wave.
What other objects can make refraction happen refraction happen?
Other objects that can make refraction happen include prisms, lenses, water droplets (creating a rainbow), and glass objects like windows or glasses. Refraction occurs when light passes from one medium to another and changes its speed, causing the light to bend.
Why do objects look distorted under water?
A ray of light will change direction when going out of water, into the air. This is called "Refraction".A ray of light will change direction when going out of water, into the air.

When a ray of light hits a surface two things will happen to the light. What are they?
When a ray of light hits a surface, two things can happen: reflection, where the light bounces back off the surface, and refraction, where the light enters the material and changes direction.
When will acceleration happen?
Acceleration occurs when an object changes its velocity, either by speeding up, slowing down, or changing direction. It can happen when a force is applied to the object, causing it to accelerate in the direction of the force.
What can happen to light traveling through a glass filled with water?
Light traveling through a glass filled with water will experience refraction, causing it to change speed and direction. The change in speed is due to the difference in optical density between the glass, water, and air. The bending of light at the interface of water and glass is what causes the phenomenon of refraction.
What happen to an object when there is unbalaced force acting on it?
When an object experiences an unbalanced force, it will accelerate in the direction of the force. The object's velocity will change, either speeding up, slowing down, or changing direction depending on the direction and magnitude of the force.
What is most likely to happen when a light ray passes from air into water?
The light ray will change its direction and bend towards the normal as it enters the water due to a decrease in the speed of light. This is known as refraction.
