The electrical charge on an atom as a whole is

Physics

dangina [55]4 years ago
4 0

The electrical charge of an atom is determined by the number of electrons it has gained/lost. Electrons have a negative charge. We will let "e" be the amount of electrical charge carried by an electron.

If the atom has not lost or gained any electrons, it has a neutral, or zero, charge.

If the atom has 2 extra electrons, the atom is overall negatively charged with a charge equal to -2e.

If the atom has lost 2 electrons, the atom is overall positively charged with a charge equal to +2e.

If you want the charge quantities in Coulombs, use the conversion rate:

e = 1.6×10⁻¹⁹C

dusya [7]

Answer:

Gamma rays

Explanation:

The penetrating power of gamma rays is maximum as compared to beta and alpha rays. Gamma rays are nothing but the photons i.e. the packets of energy. Their energy range lies from kilo electron volts to 8 mega electron volts. It is emitted during the decay of many radioactive isotopes, such as U-238 and I-131. A large amount of energy is produced in decay of uranium 238.

Hence, the correct option is " gamma rays ".

How far will the ball go before being caught one meter above the ground?
Reil [10]

Answer:

32 meters

Explanation:

Given:

x₀ = 0 m

y₀ = 1 m

y = 1 m

v₀ₓ = 18 cos 52° m/s

v₀ᵧ = 18 sin 52° m/s

aₓ = 0 m/s²

aᵧ = -9.8 m/s²

Find: x

First, find the time it takes for the ball to be caught.

y = y₀ + v₀ᵧ t + ½ aᵧt²

1 = 1 + 18 sin 52° t + ½ (-9.8) t²

0 = 14.2 t − 4.9 t²

0 = t (14.2 − 4.9 t)

t = 0 or 2.89

It takes 2.89 seconds to be caught.  The horizontal distance traveled in that time is:

x = x₀ + v₀ₓ t + ½ aₓt²

x = 0 + (18 cos 52°) (2.89) + ½ (0) (2.89)²

x = 32.1

Rounded to two significant figures, the ball travels 32 meters.

galben [10]

When cattle are processed, the most likely use for the animals' skin is in

the production of Leather.

<h3 /><h3>Animals used for Leather production</h3>
  • Cattle
  • Goat
  • Crocodile etc.

The commonly used animals in leather production is however cattle and

they amount for a large percentage of leather present today. They also

involve various techniques such as tanning and crusting to ensure

conversion to leather.
