What is the distance traveled by an object that moves with an average speed of 6.0 meters per second for 8.0 seconds

Answers

The distance traveled by the object is 48 m.

The given parameters;

average speed of the object, = 6 meters per second

time of motion of the object, t = 8 s

The distance traveled by the object is calculated as follows;

s = ((v+ u)/(2) )* t

where;

(v+u)/(2)  is the average speed of the object

Now, substitute the given values and solve for the distance traveled by the object;

s = ((v+ u)/(2) )* t\n\n\s = 6 * 8\n\n\s = 48\ m

Thus, the distance traveled by the object is 48 m.

Explain why a battery causes charge to flow spontaneously when the battery is inserted in a circuit

Answers

Batteries supply electrons to the circuit by releasing negatively charged atoms or ions. These ions are produced by the batteries through a chemical reaction that spontaneously occurs within the battery. So the negative end of the battery pushes the ions towards the positive end of the circuit with the help of the voltage. This is why eventually, batteries "run out" when the electrode is used up and the chemical reaction can no longer continue.

(a) What is the magnitude of the tangential acceleration of a bug on the rim of a 12.5-in.-diameter disk if the disk accelerates uniformly from rest to an angular speed of 75.0 rev/min in 3.80 s

Answers

Answer:

Explanation:

Given:

d=12.5in=0.3175m

r=d/2=0.3175/2=0.15875m

ωf=75rev/min=7.85rad/s

t=3.80s

The angular acceleration

\alpha = (\omega _f - \omega _i)/(t)=(7.85-0)/(3.80)=2.07rad/s^2

Tangential acceleration

\alpha =r\alpha =0.15875*  2.07=0.33m/s^2
