Explanation:
The given data is as follows.
mass = 0.20 kg
displacement = 2.6 cm
Kinetic energy = 1.4 J
Spring potential energy = 2.2 J
Now, we will calculate the total energy present present as follows.
Total energy = Kinetic energy + spring potential energy
= 1.4 J + 2.2 J
= 3.6 Joules
As maximum kinetic energy of the object will be equal to the total energy.
So, K.E = Total energy
= 3.6 J
Also, we know that
K.E = 
or, v = 
= 
= 
= 6 m/s
thus, we can conclude that maximum speed of the mass during its oscillation is 6 m/s.
Light travels in electromagnetic waves in the form of photons. What do photons travel in? Can a frequency have weight? Carry weight? According to Einstien a photon with energy proportional to its frequency basically explains ultraviolet light(among other things), so does that mean light travels within a "larger" version of itself?
We know that light doesn't need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels.
Light contrasts with sound, which travels through the air (or some other material medium). If you're stationary with respect to the air, then the speed of sound is the same in all directions. But if you're moving with respect to the air, the speed of sound will be the same in all directions relative to the air---which means that sound coming up in front of you will seem faster and sound catching up to you from behind will seem slower.
If light were a disturbance in a medium, it would exhibit the same behaviour. But light never does---its speed is the same under all circumstances. So it does you no good to postulate an aether. You can still do it, but it makes the theory more complicated than necessary. The only reason to postulate an aether is that you're uncomfortable with the idea of waves not needing a medium. But our modern understanding of quantum mechanics is that all kinds of particles have a wavelike nature, so, if you accept that matter can travel through empty space, you should have no problem accepting the same for light.
so it's true
Answer:12.206 cm,
Explanation:
Given
Insect walks 15 cm to the right
so its position vector is
Now it moves 10 cm up so its new position vector
Now it moves 8 cm left so its final position vector is
so its displacement is given by
For direction, let \theta is the angle made by its position vector with x axis
Answer:
The vibrations will put the particles into suspension reducing the frictional forces between them.
Explanation:
The downslope movement of surface material under the direct influence of gravity is called "Mass Wasting." Mass wasting plays a vital role in transferring the products of weathering from their original sites to lower-lying places where the agents of erosion can pick them up for transporting a longer distance.
There are 2 main types of mass wasting;
1. rapid mass movements
2. slow mass movements.
Shearing of soil grains from S-waves rounds jagged corners reducing frictional resistance. Also, Shaking from the seismic waves increases the water content of the material.
Mass movements are part of a continuum of erosional processes between weathering and stream transport. Mass movement causes regolith and rock to move down-slope where sooner or later the loose particles will be picked up by another transporting agent and eventually moved to a site of deposition such as an ocean basin or lake bed.
Mass movement processes are occurring continuously on all slopes; some act very slowly, others occur very suddenly, often with disastrous.
How earthquake cause mass movement
1. Earthquake causes vibrations and this will put the particles into suspension reducing the frictional forces between them.
2. It also cause the shaking from the seismic waves increases the water content of the material.
Answer:
no
In particle physics, a magnetic monopole is a hypothetical elementary particle that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). A magnetic monopole would have a net "magnetic charge".
