Answer: Corpuscular.
Explanation:
There is a theory called the Corpuscular Theory of Light, which says that light is made of small particles called "corpuscles".
But as we know, light has a duality associated to it (it behaves like a wave and like a particle), and here is where one of the largest problems of this theory appears, because it does not explain things like diffraction or interference.
Then the correct option is corpuscular.
Answer:
Explanation:
The figure is not provided and we don't know the force applied to the books.
Therefore, here we are going to assume the force applied is 3 N:
F = 3 N
We can find the acceleration of the stack of books by using Newton's second law of motion, which states that the net force on an object is equal to the product between its mass and its acceleration:
where
F is the force
m is the mass
a is the acceleration
In this problem we have
m = 1.5 kg is the mass of the books
Therefore, the acceleration is:
Answer:
Explanation:
To estimate the focal length of a convex lens follow the following steps.
1. take a convex lens.
2. Stand near a window which is just opposite to a wall.
3. Look at a tree which is far away from the window by the convex lens.
4. focus the image of the tree on the wall which is opposite to the window.
5. You wll observe that by changing the position of convex lens a sharp and inverted and small image is seen on the wall.
5. Now measure the distance between the lens and the wall.
7. This distance is the rough focal length of the convex lens.
A line that is falling towards the x axis represents an object that is negatively accelerating, or slowing down. When the line hits the x axis, the object has stopped moving. If the graph continues below the x axis, the object has changed direction and is moving backwards at increasing velocity.
Explanation:
Newton's second law shows that there is a direct relation ship between force and acceleration . the grater force that is applied on a object of given mass the more the accelerate. for example doubling the force in the object doubles it's acceleration.
