Answer:
Anions have more electrons than protons and so have a net negative charge. Cations have more protons than electrons and so have a net positive charge. Zwitterions are neutral and have both positive and negative charges at different locations throughout the molecule.
Explanation:
Answer:
0.301 m
Explanation:
Torque = Force × Radius
τ = Fr
40.0 Nm = 133 N × r
r = 0.301 m
The mechanic must apply the force 0.301 m from the nut.
Answer:
E) The average velocity of the car is 90.0 miles per hour in the direction of motion.
Explanation:
Given;
distance covered by the car, d = 90 miles
time taken, t = 60 minutes = 1 hour
The average velocity of the car is given by change in displacement per change in time;
V = Δd / Δt
Therefore, the average velocity of the car is 90.0 miles per hour in the direction of motion.
<span>The change in the kinetic energy of the object as the speed changes is proportional to the square of the factor by which the speed changes. For example if the speed of the object becomes double, its kinetic energy changes to four times the initialkinetic energy. Please put brainliest ! :D
