<span>The last main subatomic particle to be discovered was the
antihelium-4. It was discovered on 2011
and it is measured and produces through the STAR detector. The Antihelium-4 was discovered accidentally
when an experiment was conducted. It is
also the first particle that was discovered by the means of experiment.</span>
Mechanical advantage (MA = slope/height)
here length of slope = 9Hheight = H so mechanical advantage = ---- 9H/H= 9
Michael Faraday first discovered Electromagnetic Induction in 1830. His experiment that proved this the following: H<span>e moved a permanent magnet in and out of a coil or a single loop of wire. And it induced an </span>Electro M<span>otive </span>F<span>orce or </span>emf. In other words, the moving magnet produced a Voltage, and therefore a current. Michael Faraday’s famous law gives answer of the question of the dependence of the voltage: T<span>he magnitude of the voltage is proportional to the rate of change of the flux. It is false that the voltage can not be increased by moving a magnet towards a coil. It is increased.</span>

Answer:
11,627.91 kg/m^3
Explanation:
The computation of the density of the material is shown below
Given that
Mass , m = 1 kg
Height, H - 47 mm = 0.047 m
Diameter, d = 49 mm = 0.049 m
Now radius, r = D ÷ 2
= 0.049 ÷ 2
= 0.0245
Volume = πr^2h
= 3.14 × (0.0245)^2 × 0.047
= 0.000086m^3
Now the density of the material is
= mass ÷ volume
= 1÷ 0.000086m^3
= 11,627.91 kg/m^3
