Very easy....4 millimeters is the growth every year..as 720 mm is the final one...we can divide it by 4mm to obtain the answer..I.E=180years

(720 millimeters) / (4 millimeters/year) = 180 years

I'm pretty sure that's the only thing you could do with these two numbers
that would give you an answer with units of years .

A body-centered cubic lattice has a lattice constant of 4.83 Ă. A plane cutting the lattice has intercepts of 9.66 Å, 19.32 Å, a
anastassius [24]

Answer:

Miller Indices are [2, 4, 3]

Solution:

As per the question:

Lattice Constant, C = 4.83 \AA

Intercepts along the three axes:

\bar{x} = 9.66 \AA

\bar{x} = 19.32 \AA

\bar{x} = 14.49 \AA

Now,

Miller Indices gives the vector representation of the atomic plane orientation in the lattice and are found by taking the reciprocal of the intercepts.

Now, for the Miller Indices along the three axes:

a = \frac{1}{9.66}

b = \frac{1}{19.32}

c = \frac{1}{14.49}

To find the Miller indices, we divide a, b and c by reciprocal of lattice constant 'C' respectively:

a' = \frac{\frac{1}{9.66}}{\frac{1}{4.83}} = \frac{1}{2}

b' = \frac{\frac{1}{19.32}}{\frac{1}{4.83}} = \frac{1}{4}

c' = \frac{\frac{1}{14.49}}{\frac{1}{4.83}} = \frac{1}{3}

two teams are playing tug of war. team a pulls to the right with a force of 450n .team b pulls to the left with a force of 415 n
Alex_Xolod [135]

Explanation:

It is given that, two teams are playing tug of war.

Force applied by Team A, F_A=450\ N

Force applied by Team B, F_B=415\ N

We need to find the net force acting on the rope. It is equal to :

F_{net}=F_A-F_B

F_{net}=450-415

F_{net}=35\ N

So, the net force acting on the rope is 35 N and it is acting toward right. Hence, this is the required solution.

If you were creating a lamp by hand what type of material would you chose for the wiring and what material would you chose to co
il63 [147K]
A lot of it is all experimental as long as you are taking caution of safety while doing it. I personally would use copper wiring mainly for the fact that it is a nice conductor. For the wrap around the wiring i usually would use black or red electrical tape just because it has very nice insulator properties and is safe to use.
