Answer:
C = 74.53°
Explanation:
Let the magnitudes of 5.00 and 9.00 be vectors A and B respectively, hence the dot product of this vector is defined as
A.B = |A||B|cosC; let C be the angle between the vectors
12 = 5×9 cos C
Hence cos C = 12/45
C = cos^-1(12/45)
C = 74.53°
Answer:
Potential energy
Explanation:
Potential energy is stored energy and the energy of position––gravitational energy. There are several forms of potential energy. Electrical Energy is the movement of electrical charges. Everything is made of tiny particles called atoms.

change in velocity=final velocity-initial velocity=9-3=6m/s
acceleration=change in velocity/time
=6/3=2m/s²
The waste management and food and drink packages are being designed to combat the challenge to reusing the waste and reccycle the waste. Tremendous researches are being carried out to find out less polluting or non polluting labels and other materials, which can be easily recycled.
