Which radiation has no electric charge associated with it?

1 answer:

joja [24]3 years ago

3 0

Answer:

Gamma radiation

Explanation:

There are three types of ionizing radiation:

- Alpha radiation: it consists of alpha particles, which are nuclei of helium (so, they contain 2 protons and 2 neutron) --> therefore, they have a net charge of +2 (given by the positive charge of the two electrons)

- Beta radiation: it consists of electron (in case of beta-minus radiation) or positrons (in case of beta-plus radiation). Therefore, in both cases the radiation is electrically charged: charge -e for the electrons, charge +e for the positrons

- Gamma radiation: it consists of high-energy photons. Since photons are electrically neutral, gamma radiation has no electric charge associated with it.

21 kg brick v=6.1 m/s sticks to a 2.9 kg cart v=.26 m/s

vovikov84 [41]

Answer:

v = 6.05 m/s

Explanation:

The mass of the brick, M = 21 kg

The velocity of the brick, U = 6.1 m/s

The mass of the cart, m = 2.9 kg

The velocity of the cart, u = 0.26 m/s

The combined mass of the brick and the cart, v = ?

According to the law of conservation of linear momentum,

Combined final momentum = sum of the initial momentum

(M + m)v = MU + mu

v = MU + mu / M + m

= 21 x 6.1 + 2.1 x 0.26 / (21 + 0.26)

= 6.05 m/s

Hence, the combined velocity of the cart and the brick is, v = 6.05 m/s

Usually the force of gravity on electrons is neglected. To see why, we can compare the force of the Earth’s gravity on an electr

miv72 [106K]

Answer:

$6.4\cdot 10^{-15} N$

Explanation:

The electric force exerted on the electron is given by:

$F=qE$

where

$q=1.6\cdot 10^{-19}C$ is the magnitude of the electron charge

E = 40000 V/m is the electric field

Substituting,

$F=(1.6\cdot 10^{-19} C)(40000 V/m)=6.4\cdot 10^{-15} N$

By comparison, the gravitational force exerted on the electron is:

$F=mg$

where

$m=9.10939\cdot 10^{-31} kg$ is the mass of the electron

g = 9.8 m/s^2 is the acceleration due to gravity

Substituting,

$F=(9.10939\cdot 10^{-31} kg)(9.8 m/s^2)=8.93\cdot 10^{-30}N$
