The electric field across the plates is defined by

E = V / d .............. where V is the potential difference and d the distance that separates the plates.

E = 12 Volts/ 0.25 meters = 48 V/m

kifflom [539]

Answer:

Activation Energy

Explanation:

Effective collisions are those that result in a chemical reaction. In order to produce an effective collision, reactant particles must possess some minimum amount of energy. This energy, used to initiate the reaction, is called the activation energy.

What is an atom? Give three 3 examples.​
Assoli18 [71]

Answer:

<u>Atom</u><u> </u><u>is </u><u>particle</u><u> </u><u>of </u><u>matter</u><u> </u><u>that </u><u>uniquely</u><u> </u><u>defines</u><u> </u><u>a</u><u> </u><u>chemical</u><u> </u><u>element</u><u>.</u>

Examples of atom:

  • Hydrogen [ H]
  • Neon [Ne]
  • Argon [A]
  • Iron [Fe]
  • Calcium [Ca]

<h3>About Atom:</h3>

Atom consists of a central nucleus that is usually surrounded by one or more electrons .Each electron is negatively charged. The nucleus is positively charged and contains one or more relatively heavy particles known as protons and neutrons.

An early model of the atom was developed by the physicist Ernest Rutherford in 1913. He was the first to suggest that atoms are like miniature solar systems except that the attractive force is not caused by gravity, but by opposing electrical charged.

Hope this helps....

A bullet of .05 kg is fired into a block of wood. Knowing that the bullet left the gun with a muzzle velocity of 350. m/s, and t
Lunna [17]

We know, Impulse of a body is change in momentum.

Also, the final velocity of wood block is 0 m/s.

So, Impulse = Final Momentum - Initial Momentum

Impulse = 0 - ( 0.05 kg × 350 m/s )

Impulse = - 17.5 kg m/s

Therefore, the impulse exerted by the wood on the bullet is -17.5 kg m/s .

A sound wave with a power of 8.8 × 10–4 W leaves a speaker and passes through section A, which has an area of 5.0 m2. What is th
statuscvo [17]
The intensity of the sound wave is defined as the ratio between the power of the wave and the area through which the wave passes:
I= \frac{P}{A}
where
I is the intensity
P is the power
A is the area

If we use the data of the problem, P=8.8 \cdot 10^{-4}W and A=5.0 m^2, we find the intensity of the sound wave:
I= \frac{P}{A}= \frac{8.8 \cdot 10^{-4} W}{5.0 m^2}=1.76 \cdot 10^{-4} W/m^2
