Kilogram(kg)
It's not the SI unit of mass in the metric system however.

Answer:

The correct answer is gram (g).

Explanation:

The metric system uses grams (g) as the fundamental unit of measurement of mass. This system applies the idea that units increase and decrease by a power of 10. This means that a kilogram (kg) is 1000 times heavier than a gram (g), and a gram is 1000 times heavier than a milligram (mg).

Have a nice day!

Contrast the average speed and the instantaneous speed of runner in a race.

ehidna [41]

Average speed of the runner is the rate at which the runner covers the total distance. Average speed of the runner in the race is given by,

Average speed = $\frac{Total distance}{Total time}$

Where

Total distance = Distance covered by the runner from initial to final position

Total time = time taken by the runner to cover entire distance

Instantaneous speed is the speed of the runner at the particular moment in the given time. Instantaneous speed is given by,

Instantaneous speed = $\frac{dx}{dt}$

x = position of the runner at time t

t = time taken to cover distance x

Hence, Average speed and instantaneous speed are different for a runner running in the race.

A square wire, 20 cm on the side, moves at constant speed parallel to the xy-plane into a region where there is a uniform magnet

Amanda [17]

Answer:

The speed of the wire is 5 m/s.

Explanation:

Given that,

Length = 20 cm

Magnetic field = 0.1 T

Current = 10 mA

Resistance $R= 10\Omega$

We need to calculate the speed of the wire

Using formula of emf

$\epsilon=Bvl$

Using formula of current

$I=\dfrac{\epsilon}{R}$

Put the value of $\epsilon$ into the formula of current

$I=\dfrac{Bvl}{R}$

$v=\dfrac{IR}{Bl}$

$v=\dfrac{10\times10^{-3}\times10}{0.1\times20\times10^{-2}}$

$v= 5\ m/s$

Hence, The speed of the wire is 5 m/s.

The law of conservation of mass states that mass can never be created or destroyed, only changed. true or faulse

Aleksandr-060686 [28]

Answer:

true

Explanation:

The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
