Answer:
the angular momentum of the paticle is 8.4i - 10.2j.
Explanation:
the angular momentum is given by:
L = m×v×r
= (1.40)×(4.00i - 3.30j)×(1.50i + 2.20j)
= (1.40)×[(4.00×1.50)i - (3.30×2.20)j]
= (1.40)×(6i - 7.26j)
= 8.4i - 10.2j
Therefore, the angular momentum of the paticle is 8.4i - 10.2j.
That's a perfect example of a chemical change,
because a new substance is formed.
Test the shampoo on different subjects with different hair types (Ex thick, thin) Keep the variables the same for each subject using constants, independent , and dependent variables to test the claim. See if there is any difference in the girls who used the shampoo with the secret ingredient Vs girls who used a regular shampoo with out that ingredient.
Answer:
Explanation:
The density of the magnetic flux is given by the following formula:
The normal vector A and the vector of the magnitude of the magnetic field are perpendicular, then, the angle is zero:
The magnitude of the magnetic field is calculated by using the formula for B at a distance of x to a point in the plane of the loop:
For x = 0 you have:
R is the radius of the circular loop and its values is:
Then, you replace in the equation for B with mu_o = 4\pi*10^-7 T/A:
and the density of the magnetic flux is
