A car's velocity changes from 40 m/s to 30 m/s in 40 seconds. What is the
valina [46]

Answer:

- 0.25m/s²

Explanation:

Given parameters:

Initial velocity  = 40m/s

Final velocity  = 30m/s

Time taken  = 40s

Unknown:

Acceleration of the car  = ?

Solution:

Acceleration is the rate of change of velocity with time.

 So;

  Acceleration  = \frac{Final velocity - Initial velocity }{time }  

 Acceleration  = \frac{30  - 40}{40}    =  - 0.25m/s²

This implies that the car will decelerate at a rate of 0.25m/s²

How many electrons have been removed from a positively charged electroscope if it has a net charge of 6x10-11?
faltersainse [42]

Answer:

<h3>Because one Coulomb of charge is an abnormally large quantity of charge, the units of microCoulombs (µC) or nanoCoulombs (nC) are more commonly used as the unit of measurement of charge. To illustrate the magnitude of 1 Coulomb, an object would need an excess of 6.25 x 1018 electrons to have a total charge of -1 C.</h3>
