The angle between the two vectors is 126° 52' 11".
The given parameters;
vector A = 3.00i + 1.00j
vector B = 1.00i + 3.00j
The angle between the two vectors is calculated as follows;
The dot product of vectors A and B is calculated as;
A.B = ( 3i + 1j ) . ( 1i +3j )
= ( 3 × 1 ) + ( 1 × 3 )
= 3 + 3
= 6
The magnitude of vectors A and B is calculated as;
|A| =
|B| =
The angle between in two vectors is calculated as;
Therefore, the angle between the two vectors is 126° 52' 11".

The element Nitrogen is
usually present in almost all proteins, and it also forms strong bonds due to
its ability to form a triple bond with its self, also to other elements.
<span>The nitrides use a variety
of different oxidation and almost all the oxides forms gasses are at 25 degrees
Celsius. The oxide of nitrogen are acidic, thus, easily attaching protons.</span>
Answer:
Extreme temperatures can increase demand for heating and cooling, and the resulting increases in electricity demand can push up fuel and electricity prices.
Explanation:
Power is calculated as work per unit time, and work in turn is calculated as force multiplied by distance. In this case, the force required is equivalent to the weight of the barbell multiplied by acceleration due to gravity.
P = W/t = Fd/t = mgd/t = (200 kg)(9.81 m/s^2)(2 m)/2.2 s = 1783.64 Watts.
