Alpha emission is the process results in a change in mass number. Option B is correct.

<h3>What is mass number?</h3>

The total number of protons and neutrons in an atomic nucleus is known as the mass number, often known as the atomic mass number or nucleon number.

It's about the same as the atom's atomic mass, expressed in atomic mass units.

The alpha particle is a helium nucleus with two protons and two neutrons in an alpha decay or alpha emission. The number of protons and neutrons is reduced by two as a result of this action.

The quantity of protons and neutrons is affected by gamma emission descent. Also, while electron capture has no effect on the number of neutrons, it does raise the 1 also number of protons by one.

Alpha emission is the process results in a change in mass number.

Hence option B is correct.

Why the sun emits most of its energy in the form of visible light?
I am Lyosha [343]

Human eye could perceive this visible light and used it to look at the objects.

<u>Explanation: </u>

There are 3 forms of radiation emitted by the sun. They are Infrared radiation, Ultra Violet radiation as well as visible radiation.

Visible light is the type of light can perceive by the human eye and utilizes to see the objects.  

Since the sun is hotter (5800 K) than the earth, it emits mostly the radiation energy in the form of this visible light.

Nerve impulses in a human body travel at a speed of about 100 m/s. Suppose a man accidentally stubs his toe. About how much time
alexandr1967 [171]

Answer:

t = 0.018 s  

Explanation:

given,

nerve impulse in human body travel at a speed of  = 100 m/s

height of the man = 1.80 m

time taken by the impulse to travel from foot to brain = ?

distance = speed × time                      

1.80 = 100 × t                                              

t =\dfrac{1.80}{100}                                    

t = 0.018 s                            

hence, the time taken by the nerve to reach brain from toe is 0.018 s

Why do the planets in our solar system stay in their positions?.
SVETLANKA909090 [29]
The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.

A student ran 60 meters in 1 minute. Calculate the speed. Provide your answer in meters per second.
Elena-2011 [213]

Answer:

Speed, S = 0.5m/s

Explanation:

Given the following data;

Distance = 30 meters

Time = 1 minute = 60 seconds

To find the speed;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

Speed = \frac{distance}{time}

Substituting into the above formula;

S = \frac{30}{60}

Speed, S = 0.5m/s
