Answer:
The dimension of the nullspace of T = 4
Explanation:
The rank/dimension theorem is explains that:
Suppose V and W are vector spaces over F, and T:V → W is linear. If V is finite dimensional, then
nullity(T) + rank(T) = dim(V).
rank(T) = dimension of T = dim(T) = dim(W) = 7
nullity(T) = dimension of the nullspace of T = dim(T) = ?
dim(V) = 11
nullity(T) = dim(V) - dim(T) = 11 - 7
nullity(T) = 4.
Answer:
Explanation:
If you are asking for how much a cubic meter of iron would weight, you need to find its density.
The density of iron taken from the periodic table is 
, therefore a single cubic meter would weight 7870 kg, which written in scientific notation would be
Answer:
The wavelength of light is 68 nm
Explanation:
Answer:
I think it's correct. Hope it helps.
FALSE, density is dependent of the iron molecules inside the bar, not the length
