Which form of emission is commonly not written in nuclear equations because they do not affect charges, atomic numbers, or mass
salantis [7]

Answer:

Gamma radiation .

Explanation:

Three types of emission result at the time of nuclear emission .

alpha emission

Beta emission

Gamma radiation emission

Gamma radiation results in the emission of gamma ray . This is a very high frequency radiation . It is not a particle having charge and mass like alpha and beta emission . So it has no effect on the mass and charge of the product that is formed after gamma radiation . The only effect it has on the product is that it reduces the kinetic energy of the emitting particles or it reduces the internal energy of the product . It causes negligible change in the mass of the product and no change in the charge of the product.

That is why , generally this product is not written in the nuclear reaction .

If a girl is running along a straight road with a uniform velocity 1.5 m/s, find her
Dafna1 [17]

Answer:

Explanation:

The definition of acceleration is the change in velocity over a period of time. If the girl's velocity is constant, that means it's not changing. Therefore, acceleration is 0 m/s/s

Question 1 of 10
Dahasolnce [82]

Answer:

They have the same rate of motion.

Explanation:

Electromagnetic radiation is a type of energy that is commonly known as light. Generally, light travels in waves, and all electromagnetic radiation travels at the same speed, which is about 3.0 × 108 ms− 1 through a vacuum.

A radio antenna broadcasts a 1.0 MHz radio wave with 30 kW of power. Assume that the radiation is emitted uniformly in all direc
kozerog [31]

Answer:

a) intensity  = 2.19 \times  10^{-6} W/m^2

b) E = 0.0406 V/m

Explanation:

given data:

Power =  30 kW

R = 33×10^3 M

1) Intensity is given as

Intensity I = \frac{P}{4\times \pi \times r^2}

= \frac{30 \times 10^3}{4\times 3.14 \times (33\times10^3)^2}

= 2.19 \times  10^{-6} W/m^2

2) electric field is given as

I = 1/2 \times \epsilon \times c \times E^2

Solving for E

E = \sqrt{\frac{2I}{\epsilon c}}

E  =\sqrt{\frac{2\times 2.19 \times 10^{-6}}{8.85\times 10^{-12}  3\times 10^8}}

E = 0.0406 V/m
