multiply grav pull by mass of astro maybe with a calculator
Answer:
A.reduce by 4.
Explanation:
In Chemistry, an alpha particle which is typically a helium nucleus has an atomic mass (number of nucleons) of four (4). Therefore, the ejection of an alpha particle by any chemical element simply means that, the mass number of that particular chemical element would be reduced by four (4).
Basically, this process is referred to as an alpha decay and can be defined as a radioactive disintegration of a chemical element that causes it to emit an alpha particle and as a result reducing its mass number by four (4).
Hence, when an element ejects an alpha particle, the mass number of that element reduces by 4.
initial momentum of 2 kg blob is given as
here we have
initial momentum of 3 kg blob is given as
here we have
So initially 2 kg Blob has most momentum before they collide
There are two systems that contain only the fundamental frequency and they are the systems C and D.
<h3>What is fundamental frequency?</h3>
The term fundamental frequency refers to the lowest frequency of a vibrating body. It does not include the overtones or the harmonics.

The distance covered by the plane is 600 km
Explanation:
The motion of the plane is a uniform motion, so at constant velocity, therefore we can use the following equation
where
d is the distance covered
v is the velocity
t is the time interval considered
For the plane in this problem,
v = 400 km/h
t = 1.5 h
Substituting, we find the distance covered:
