If a nucleus decays by successive b, a, a emissions, its mass number will Group of answer choices decrease by seven. decrease by

nirvana33 [79]

Answer:

The mass number will decrease by eight (8).

Explanation:

Given;

successive beta (b), alpha (a), alpha (a) emissions.

Generally, when a radioactive element emits a beta-particle (b), its mass number doesn't increase but its atomic number increases by 1 . $(^{0}_{-1}\beta )$

Also when a radioactive element emits an alpha-particle (a), its mass number decreases by 4, while its atomic number decrease by 2. $(^4_2\alpha)$

For the given question, a successive beta (b), alpha (a), and alpha (a) emissions = (0) + (-4) + (-4) = -8

Thus, when a radioactive element emit a successive beta (b), alpha (a), alpha (a) particles, the mass number will decrease by eight (8).

True or false: in applying the pythagorean theorem to vector addition, the resultant vector is given by the perpendicular vector

olganol [36]

It is False in applying the pythagorean theorem to vector addition, the resultant vector is given by the perpendicular vector

<h3>What is Pythagoras theorem ?</h3>

A useful technique for figuring out the outcome of adding two (and only two) vectors that form a right angle to one another is the Pythagorean theorem. The technique cannot be used to combine more than two vectors or to combine vectors that are not at a 90-degree angle.

The Pythagorean Theorem demonstrates how the side lengths of a right triangle can be calculated from the sum of the areas of three intersecting squares. This theorem is a very helpful tool that serves as the foundation for more intricate trigonometry ideas like the Pythagorean theorem's opposite.

an object has a constant acceleration of 3.2 m/s^2.at a certain instant its velocity is 10 m/s . what is its velocity after 5 se

aleksandrvk [35]

So here, you're looking for distance. The formula is D=vt+1/2at^2.

Lets plug in the informations.

10 m/s is our v (initial velocity)

5 second is out t(time)

3.2 m/s is our a(acceleration)

10m/s(5)+1/2(3.2m/s+5^2)

50m/s+1/2(28.2)

50m/s+14.1

Answer =64.1 m

Glad to help you out buddy. Let me know if you need help.

The energy required to change liquid at it boiling point to a gas is

soldi70 [24.7K]

Answer:

latent heat, also called the heat of vaporization, is the amount of energy necessary to change a liquid to a vapour at constant temperature and pressure. The energy required to melt a solid to a liquid is called the heat of fusion, and the heat of sublimation is the energy
