We're millions of miles away from mars
Answer:
It reduces the melting point due to a defect in the arrangement of the crystal lattice.
Explanation:
The presence of impurities creates a disorderliness in the uniformity of the crystal structure. It lowers the melting point by a few degrees because it becomes easier to overcome the intermolecular force of attraction.
It makes the array of crystals disordered.
Lattice is a long chain three-dimensional arrangement of the molecules, atoms or ions in a crystal structure.
Explanation:
F = qvBsin(angle)
F = 1.6 x 10^-19 x 9.5 x 1.8 x Sin (90)
F = 273.6 x 10^-20N
a = F/M
M of a proton = 1.67 x 10^-27kg
a = 273.6 x 10^-20/1.67 x 10^-27
a = 1638323353.29m/s
It could be express as (A) 14 x 10 to the tenth power or (b) 4.415 x 10 to the seventeenth power.
Answer:
m = 50 [kg]
Explanation:
The potential energy can be calculated by means of the following equation.
where:
Ep = potential energy = 735 [J]
m = mass [kg]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 1.5 [m]
Now replacing:
![735=m*9.81*1.5\\m = 50 [kg]](https://tex.z-dn.net/?f=735%3Dm%2A9.81%2A1.5%5C%5Cm%20%3D%2050%20%5Bkg%5D)
