We can answer the problem by Snell's Law:
Snell's law<span> (also known as </span>Snell<span>–Descartes </span>law<span> and the </span>law<span> of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.</span>
Answer:
Tension and Gravitational Force
Explanation:
The question says that a monkey is hanging, he neither drops down to the ground nor moves up. He keeps hanging on a vertical vine.
Since, the monkey is hanging, two forces acts on the monkey, one force is due to his weight, i.e., the gravitational force which tends to pull him downwards and the other is due to the tension developed in the string which is in upward direction.
Thus to keep the monkey in the hanging state both the forces must counter balance each other and maintains the system 's equilibrium.
Therefore, both the forces must be equal.
Answer:
60°
Explanation:
Formula
360/n (if the number is an odd number) or
360/n-1 (if the number is even) (to arrive at an odd number)
SO. 5 is an odd number but not a multiple of 360, so we will use 6 an even number.
360/60-1
360/60=6 images
6-1 =5 images
Thus. the images formed will be 5.
Answer:
Impulse. Impulse is when a force is applied to an object for an amount of time.
Explanation:
It can't be momentum because momentum is the motion of a moving body, that is measured as a product of its mass and velocity.
It' cant be inertia because inertia is when an object doesn't move/ it does nothing as well as an object remaining unchanged.
And it can't be acceleration because acceleration is when how fast an object can go/ there velocity.
And that leaves us with impulse, so that's the correct one.
Hope this helped!
