Answer:
2500kg/m3
Explanation:
Mass=20g= 20×10^-3kg
Volume=8x10^-6m3
<h2>Now we know that Density = mass\volume</h2>
D= 20×10^-3/8×10^-6
=2500kg/m3
A proton has about 1836 times the mass of an electron. The best estimate of physicists is that the radius of a proton is about 8×10-16m and the radius of an electron is about 10-16m . If they are correct, then a proton has about ten times the diameter of an electron
False, metamorphic rocks are formed under pressure, is crystals are then formed into layers
“Un cuerpo rígido está en equilibrio de traslación cuando la suma de las fuerzas que actúan sobre él es nula (o fuerza neta igual cero). Un cuerpo rígido está en equilibrio de rotación cuando la suma de los torques producidos por las fuerzas que actúan sobre él es nulo(o torque neto igual a cero).”
