Rudik [331]

Answer:

m²=m¹

Explanation:

m¹v¹ + m²v² = m¹ v¹+m¹v²

m²v²= m¹v²

m²v²/v² = m¹

m² = m¹

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

Provide 2 important pitching tips you can tell someone else. softball
sveticcg [70]
I know you only need two, but here are some options to choose from.

Tip 1 - throwing a fastball. Use two points to keep your arm properly aligned your biceps brush your ear at the top of the backswing, and your pitching hand brushes your hip at release.

Tip 2 - throwing a curveball. Pictures should know that in order to maximize your curves, you should visualize a series of dots from the mound to the outside corner of the plate. Pitch along those dots.

Tip 3 - throwing a fast pitch rise. It’s possible that your wrist snap may be sideways. Play with different grips or finger pressures and try to relax them.

Tip 4 - throwing a change-up. Don’t always throw the change-up in a given situation. Make sure to change your pitch selection.

Tip 5 - throwing a drop-ball. Keep your pitching arm close to your body to avoid injury.
