Q. If the net force acting on an object is in the positive x-direction, the object moves only in the positive x-direction.
It is not true, the object will accelerate only in the x-direction, but it may be traveling in the y-direction and it could continue to do so making the path it follows a parabola. Think about a ball kicked off a cliff. There is a net force only in the y-direction (gravity) so the ball will accelerate downwards while continuing with a constant horizontal velocity.
Q What is Tyndal scattering? Tyndal scattering- When light passes throughout a colloidal solution its path is visible inside the solution. This is for the reason that the
An electron is constrained to the central perpendicular axis of a ring of charge of radius 2.2 m and charge 0.015 mC. See Section 22-6. Suppose the electron is released from rest a
Q. Does sunlight reflected off a mirror raise the temperature of the sun-rays? Answer:- A standard planar mirror will not raise the energy contained in the rays that refle
Huygens' construction; Huygens' principle (C. Huygens): The mechanical propagation of any wave (exclusively, of light) is equal to supposing that each point on the wavefront b
Surface Imperfection: These are two dimensional and refer to a region of distortions that lies around a surface having a thickness of a some atomic diameters.
The time needed for a net force of 10 newtons to change the velocity of a 5 kilograms mass by 3 meters/second is: a) 1.5 seconds b) 6 seconds c) 16.7 seconds d
how to verify the laws which govern the resistance which are connected in series
State Huygens' Principle. With the help of a suitable diagram, prove Snell's law of refraction using Huygens' Principle.
3 scenarios: You have an object such as a jar, and you submerge it under water to 50m depth. (Every 10m down increases pressure by 1 bar, thus the pressure is 5 bar). Scenario 1:
If the angle of incidence is 60 degrees,then what is the angle of deviation?
