Answer:
Mechanical advantage = 3
Explanation:
Given:
Weight = 300 N
Force load = 100 N
Find:
Mechanical advantage:
Computation:
Mechanical advantage = Weight/Force Load
Mechanical advantage = 300/100
Mechanical advantage = 3
Since density would be D=M/V, we’d have to literally divide 20 by 4.
20 divided by 4 is 5, so the density of the mineral sample is 5 grams.
Please correct me if I am wrong!
Waves: can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.
A wave refers to a disturbance in a medium that progressively transports energy from its source to another location, without transporting matter.
In Physics, there are two main (2) types of wave and these are;
- <u>Mechanical waves:</u> an example is sound wave, which requires a medium for its propagation.
- <u>Electromagnetic waves:</u> an example is light wave, which doesn't require a medium for its propagation and can travel through a vacuum or an empty space.
Basically, some of the phenomenon associated with waves include the following:
I. Doppler shift (Doppler effect).
II. Reflection.
III. Refraction.
IV. Diffraction.
V. Constructive interference.
VI. Destructive interference.
In conclusion, all waveform can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.
I'd say if there is less force applied than there was less movement.
Particles are always vibrating, as temperature rises, thermal energy is being released into the particles, so they start vibrating faster in order for them to release the thermal energy.
