Answer:
The correct answers are It is the resistance of an object to changes in its motion, and It is a force
Answer:
Atoms with the same number of protons but with different electrical charges are different ions
Explanation:
Ions are defined as those atoms or molecules which carry charge
Answer:
Exercise 1;
The centripetal acceleration is approximately 94.52 m/s²
Explanation:
1) The given parameters are;
The diameter of the circle = 8 cm = 0.08 m
The radius of the circle = Diameter/2 = 0.08/2 = 0.04 m
The speed of motion = 7 km/h = 1.944444 m/s
The centripetal acceleration = v²/r = 1.944444²/0.04 ≈ 94.52 m/s²
The centripetal acceleration ≈ 94.52 m/s²
Answer with Explanation:
We are given that
A.Mass,m=12 kg
Speed,v=1.5m/s
Net force in x direction must be zero
Net force in y direction
Power,P=Fv
Where 
B.Substitute the values
