Answer:

Fundamental quantities are the base quantities of a unit system, and they are defined independent of the other...

• Derived quantities are based on fundamental quantities, and they can be given in terms of fundamental quantities.

• In SI units, derived units are often given names of people such as Newton and Joule.

A parallel-plate capacitor is connected to a battery. What happens to the stored energy if the plate separation is doubled while

zlopas [31]

Answer:

new energy of the capacitor is half that of initial energy

Explanation:

As we know that the energy stored in the capacitor is given as

$U = \frac{1}{2}CV^2$

here we know that capacitance of parallel plate capacitor is given as

$C = \frac{\epsilon_0 A}{d}$

V = voltage of battery

so now we have capacitor remains connected to the same battery and the separation between the plates is doubled

so we have

$C' = \frac{\epsilon_0 A}{2d}$

so now the energy stored between the plates is

$U = \frac{1}{2}(\frac{C}{2})V^2$

so new energy of the capacitor is half

A playground ride requires 21 seconds to make one complete revolution

luda_lava [24]

The angular speed of the playground ride is determined as 0.3 rad/s.

<h3>What is angular speed?</h3>

Angular speed is the rate at which an object changes it angles which we measure in radians in a given time.

<h3>Angular speed of the ride</h3>

The angular speed of the ride if the ride makes one complete revolution is calculated as follows;

ω = θ/t

ω = 2π/t

where;

ω is angular speed of the ride
t is time of motion of the ride

one complete revolution = 2π radians

ω = 2π/21

ω = 0.3 rad/s

Thus, the angular speed of the playground ride is determined as 0.3 rad/s.
