MgCl2 is Magnesium chloride
Answer
given,
height of counter = 1.20 m
horizontal distance from base = 1.6 m
a) velocity of mug = ?
using equation of motion
t = 0.495 s
speed of the mug
s_x = v x t
1.6 = v x 0.495
v = 3.23 m/s
b) final velocity of mug in y direction
again using equation of motion
v² = u² + 2 a s
v²= 0 + 2 x 9.8 x 1.2
v = √23.52
v_y = 4.85 m/s
now, direction
For this case we have that by definition, a micrometer is equivalent to a thousandth of a millimeter, that is, 0.001 millimeters.
Then, in other words, we have 0.001 millimeters in a micrometer.
Answer:
In a micrometer there are 0.001 millimeters.
Number 5 goes to letter e
