What is Lens?
A lens is a transmissive optical tool that uses refraction to focus or disperse a light beam. A compound lens is made up of multiple simple lenses (elements), typically arranged along a common axis, as opposed to a simple lens, which is one solid piece of transparent material. Glass or plastic are used to make lenses, which are then polished or moulded into the desired shape. In contrast to a prism, which simply refracts light without focusing it, a lens can focus light to create an image. Lenses are also devices that focus or disperse waves as well as radiation other than visible light, such as <u>explosive lenses, microwave lenses, particle lenses, and acoustic lenses</u>.
Lenses are a common component of <u>telescopes</u><u>, binoculars, and cameras, among other imaging devices</u>.

The answer is Galileo Galilei. Hope this helps :)
Answer:
The short answer is that velocity is the speed with a direction, while speed does not have a direction.
Explanation:
Speed is how fast an object is moving. It is calculated by the displacement of space per a unit of time. Velocity is the rate at which an object changes position in a certain direction. It is calculated by the displacement of space per a unit of time in a certain direction. Velocity deals with direction, while speed does not.
Answer:
The mass of the block of ice is 90.91 kg.
Explanation:
The expression for the equation of motion is as follows;
Here, u is the initial speed, a is the acceleration, t is the time and s is the distance.
Calculate the acceleration of the given block.
Put t= 5 s, s= 11 m and u= 0 in the above expression.
The expression for the force in terms of mass and acceleration is as follows;
F= ma
Here, F is the force and m is the mass.
Put F= 80 N and .
80= m(0.88)
m=90.91 kg
Therefore, the mass of the block of ice is 90.91 kg.
Answer with Explanation:
"Wind" is abundant everywhere, thus it becomes one of the options for producing <em>electricity</em> in the world. Although it is said to be one of the cleanest sources, it also has an environmental impact on the society.
One of these is the amount of land that is being used when wind turbines are being installed. The wind turbines are the ones which allow the conversion of wind to electricity. Those that are located offshore require <u>bigger spaces. </u>
Another impact is <em>its threat to flying animals like birds and bats.</em> Some claim that these animals sometimes <em>collide with the wind turbines that spin causing their death.</em>
The wind turbines also produce noise pollution that <u>bothers residents who are living nearby. </u>
These are just some of the environmental impacts that occur when wind energy is converted into electricity.
