The distance from the lens to the focal point is called the focal length.
What is a converging lens?Converging lenses, commonly referred to as convex lenses, have thicker centers and narrower upper and lower margins. The edges are outwardly curled. This lens has the ability to concentrate a beam of parallel light rays coming from the outside onto a spot on the opposite side of the lens. Convex lenses come in three different varieties, each with a unique structure.Convex mirrors are used in a car's side wing mirrors and rearview mirrors. This is so that the driver can see a wider area than the average person because of the distorted image that is created. aids the driver in keeping a closer eye on the road and vehicles in the back.Due to the greater field of view, it provides than usual, it is also utilized in driving mirrors and store security mirrors. Using blind corner mirrors to see around blind corners on the road is advantageous. By being able to see the traffic around tight turns, it improves road safety.To learn more about converging lens, refer to

Put yourself in usual bolts running shoes-how would you feel about breaking your own world record ?
Answer:
Honestly if I broke MY OWN record, I would be shocked.
Explanation:
Breaking your own record means either nobody has succeeded your record therefor its still YOUR record, or nobody had thought to even try to break your record. It would be great to push yourself to further limits and break a record you once made. You should be very proud if you did, because not only did no one break your record yet, you broke it yourself.
If putting yourself in Usain Bolt running shoes, when you break your own record, it either means that no one has ever beaten it.
What is the world record by Usain Bolt?100 m in 9.58 seconds is the world record by Usain Bolt at the 2009 IAAF World Championships,
They predict that times will begin to plateau and that it will get harder and harder to beat the record.
Although the sub-nine seconds are on, they think: "It's safe to say that someone will break the nine-second barrier – not necessarily in our lifetime, but it will happen one day."
It would be fantastic to challenge yourself and surpass a previous record.
Therefore, if you did, you should be extremely proud because not only has no one else yet broken your record, but you also accomplished it yourself.

When you throw a sheet of paper and a stone from a certain height under what condition will the two fall to the ground at the same time?
Answer:
when there is no resistance.( in a vacuum)
Explanation:
this is because of acceleration due to gravity that is equal on both objects.
The weight of an object can be determined by multiplying the mass of the object by which of the following?
A) the object's velocity
B) the object's size
C) the object's change in speed
D) the object's acceleration due to gravity
Answer:
D.
Explanation:
Weight is determined using the formula [tex]w=mg[/tex] (m=mass, w-weight, g=gravity). In physics, weight is the force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity.

Scientists think that birds and other animals, such as sea turtles, may use Earth’s magnetic field to help them navigate. Research which animals might find their way using Earth’s magnetic field and investigate the evidence scientists have found that supports the idea. What would happen to the animal if Earth’s magnetic field were reversed?
Answer:
Magnetoreception (also magnetoception) is a sense which allows an organism to detect a magnetic field to perceive direction, altitude or location. This sensory modality is used by a range of animals for orientation and navigation, and as a method for animals to develop regional maps

What is force?It is that magnitude that affects a body and is responsible for changes in its state of motion, according to quantum mechanics ordered from weakest to strongest are:
Gravitational force is the force exerted by one mass on the other, being a weak force.Weak nuclear force is the force responsible for radioactive decay.Electromagnetic force is the force that affects electrically charged particles and has two directions (attraction-repulsion).Strong nuclear force is the force that keeps the nuclei of atoms stable, being stronger than the electromagnetic force.Therefore, we can conclude that four fundamental forces are recognized at the quantum level ordered from weakest to strongest are: the gravitational force, the weak nuclear force, the electromagnetic force and the strong nuclear force.

What is the mass of an object with a velocity of 24.1 m/s and a momentum of 28.3 kg m/s?
Answer:
1.17427...kg
Explanation:
Assumptions: no friction, no air resistance, no internal resistance, and it is 1 dimensional travel for velocity.
p=mv, where p is momentum, m is mass, and v is velocity
28.3=24.1(m)
divide both sides by 24.1
you get 1.174273859
Answer:
[tex]\boxed {\tt 1.17427386 \ kilograms}[/tex]
Explanation:
The formula for momentum is:
[tex]p=mv[/tex]
From this formula, we know that mass can be found by dividing the momentum by the velocity.
[tex]\frac{p}{v}=m[/tex]
The momentum is 28.3 kg m/s and the velocity is 24.1 m/s
[tex]p=28.3 \ kg \ m/s \\v=24.1 \ m/s[/tex]
[tex]\frac{28.3 \ kg \ m/s }{24.1 \ m/s} =m[/tex]
Divide. The meters per second or "m/s" will cancel each other out.
[tex]\frac{28.3 \ kg}{24.1} =m[/tex]
[tex]1.17427386 \ kg=m[/tex]
The mass of the object is 1.17427386 kilograms.

The characteristic which describes an organism of kingdom Animalia is able to move on its own when compared to the plants kingdom. Thus, the correct option is A.
What are the characteristics of Animalia Kingdom?Animals are the multicellular, eukaryotic organisms in the biological kingdom Animalia. Animals are the organisms which consume organic material, breathe oxygen gas, are able to move on their own, can reproduce sexually and produce organisms which contain genetic information which is recombination of both the parents, and these organisms go through an ontogenetic stage in which their body consists of a hollow sphere of the cells, the blastula, during the embryonic development of organisms.
Organisms belong to Animal kingdom show some characteristics which are not found in the organisms which belong to the plant kingdom including movement. Animals can move on their own while plants cannot.

predict the long term cost and benefit of using renewable or non renewable resources. please help will give brainliest
Answer:
The long term cost and benefit of renewable resources is that it is most likely a one-time purchase kind of thing. For example, if you use solar energy, you only have to buy the solar panels for your roof once. However, if you use gas oil to cook, you have to keep buying since it runs out. Sunlight doesn't run out.
The long term cost and benefit of non renewable resources is that it is something you can profit off of very easily. It will take a lot of time for people to completely switch over to renewable resources, so it is something that can steadily bring in money. Examples of non renewable resources that people constantly use is oil, gas, coal, etc.
