A material that is malleable and conducts electricity is
most likely is a metal. The answer is letter C.
The physical property that makes wax good for making
sculpture molds is the melting point. The answer is letter D.
Filtration can be used to separate mixtures based on the
size of their particles. The answer is letter D.
The pucks are traveling towards one another, so their relative velocity becomes:
1.3 + 1.7 = 3 m/s
The time it will take for them to collide:
18/3 = 6 seconds
In this time, the distance each puck will cover:
Da = 1.3 x 6
= 7.8 m
Db = 1.7 x 6
= 10.2 m
Answer:1.63 m
Explanation:
Given
mass of block ![m=0.5 kg](https://tex.z-dn.net/?f=m%3D0.5%20kg)
inclination ![\theta =30^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D30%5E%7B%5Ccirc%7D)
Amount of work done ![W=4 J](https://tex.z-dn.net/?f=W%3D4%20J)
block slides a distance s along the Plane
Work done =change in Potential Energy
Increase in height of block is ![s\sin \theta](https://tex.z-dn.net/?f=s%5Csin%20%5Ctheta%20)
Change in Potential Energy ![=mg(\sin \theta -0)](https://tex.z-dn.net/?f=%3Dmg%28%5Csin%20%5Ctheta%20-0%29)
![\Delta P.E.=0.5\times 9.8\times s\sin 30](https://tex.z-dn.net/?f=%5CDelta%20P.E.%3D0.5%5Ctimes%209.8%5Ctimes%20s%5Csin%2030)
![4=0.5\times 9.8\times s\sin 30](https://tex.z-dn.net/?f=4%3D0.5%5Ctimes%209.8%5Ctimes%20s%5Csin%2030)
![s=1.63 m](https://tex.z-dn.net/?f=s%3D1.63%20m)
Answer:
the relativistic Doppler effect,
Explanation:
The emission of 21 cm from hydrogen atoms suffers from the relativistic Doppler effect, this is a current of its wavelength due to the relative speed between the source and the observer, us located on Earth.
If the object is moving away from us the shift is towards red and if the body is approaching towards us the shift is towards blue.
Also the value of the shift depends on the speed of the body.
The highest point of the wheel is the position of the wheel when its potential energy is greatest.
<h3>At what position of the wheel potential energy is greatest?</h3>
The position of the wheel when its potential energy is greatest when it is at the highest point because potential energy depends on the height of an object. If the object is at more height then it has more potential energy and vice versa.
So we can conclude that the highest point of the wheel is the position of the wheel when its potential energy is greatest.
