Answer:increasing any of them, either mass or speed by 1unit will cause an increase in energy,

Explanation:

By increasing any of them, either mass or speed will cause an increase in energy.

Because kinetic energy is proportional to mass and also directly proportional to velocity

1. Take a breaker
2. Put a sieve on it
3. Pour the mixture and shake the sieve gently
4. Wait for the flour to fall. After the flour falls pour the rice from the sieve into other beaker then do experiment again for fair testing(optional)

The electric field strength between the plates of a simple air Capacitor is equal to the voltage across the plates divided by th

exis [7]

Answer:

$d=\frac{112\,V}{1100\,\frac{V}{cm}} \\d=\frac{28}{75} \,cm=0.101818.. \,cm$

Explanation:

Recall that the equation for the electric field intensity between the plates of a capacitor is given by:

$E=\frac{\Delta V}{d}$

where E is the electric field, $\Delta V$ is the voltage across the plate of the capacitor, and "d" is the separation (distance) between the capacitor's plates.

So we need to solve for the distance in the equation above, but also make sure that the units for electric field and potential difference are in agreement. We then write the electric field strength in V/cm :

1.1kV/cm = 1100 V/cm

Now in the equation:

$E=\frac{\Delta V}{d}\\1100\,\frac{V}{cm} =\frac{112\,V}{d\\}\\d=\frac{112\,V}{1100\,\frac{V}{cm}} \\d=\frac{112}{1100} \,cm\\d=\frac{28}{75} \,cm=0.101818.. \,cm$
