Answer:- and
radiation.
Explanations:- Alpha particle is helium nucleus with two protons and two neutrons and so it has +2 charge where as gamma is a form of light, so these are rays and not particles. Since these are rays, the charges for gamma rays is zero means they are neutral.
When alpha particles are passed through electromagnetic field they are repelled by the positive plate and attracted by the negative plate as there is an attraction between opposite charges. So, the line we see towards positive plat is representing an alpha particle radiation.
Since gamma rays are neutral, they are not deflected in electromagnetic field and go straight. So, the other line in the diagram is representing gamma rays radiation.
There are two types of radiations in the image above, one which is deviated towards the negative pole and another which is passing without any deviation. The one which is deviated towards the negative field is Alpha radiation and the one which is not deviated by any pole is known as Gamma radiation.
In Alpha radiation, we get an alpha particle which has +2 charge and therefore it is attracted towards negative pole.
Charge on He molecule is +2 and it is also known as alpha particle.
In Gamma-radiations, a gamma particle is released which does not carry any charge therefore it is not deviated by any of the pole.

Answer:
<h2>mass = 29.25 g</h2>Explanation:
The denisty of a substance can be found by using the formula
Making mass the subject we have
<h3>mass = Density × volume</h3>From the question
Density = 2.34 g/mL
volume = 12.50 mL
Substitute the values into the above formula and solve for the mass
That's
mass = 2.34 × 12.50
We have the final answer as
<h3>mass = 29.25 g</h3>Hope this helps you
Answer: See description
Explanation:
Kepler's laws have three principal points:
1. planets orbit the sun in elliptical paths
2. the orbial period is related to the orbital distance by
where T is the orbital period and d is the orbital distance, T is in years and d is measured in units of the earth sun distance.
3. planets closer to the sun move faster than planets far away from it.
Newton:
Newton discovered that there is a consequence to the gravity exerted by objects: mass, the heavier the planet, the more gravitational force it posseses ( thats why we orbit the sun)
with the gravitational force newton discovered the inverse-quadratic relationship between the distance of the planets and the acceleration exerted by the force one could exert on another.
Kepler's laws were mostly based on observed evidence with quantitative relationships between the mentioned variables. Newton's laws are based on calculus and symbolic equations. While Kepler's mode is basic, Newton took another step in and build a more general model for gravity (which was improved by general relativity later). In a nutshell Newton proved the scientific causes for Kepler's laws...
