For a parallel circuit with two resistors, the total resistance is calculated from the expression:
1/R = 1/R1 + 1/R2
We are given the total resistance, R, which is 20 ohms and R2 which is 75 ohms. We calculate R1 as follows:
1/20 = 1/R1 + 1/75
1/R1 = 11/300
R1 = 27.27 ohms
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.

Answer:
0.125m/s^2
Explanation:
20-10=10
10 divided by 80=0.125m/s^2
Answer:
kinematics is a subfield of physics developed in classical mechanics that describes the motion of point , bodies (objects) , and systems of bodies (group of objects ) without considering the forces that cause them to move
