Explanation:
angular velocity is given by


w = 0.626
now tangential velocity is
V = rw
= 25 x 0.626
= 15.65 m/s
A) Both players are moving by uniformly accelerated motion, and we can write the position at time t of each of the two players as follows:


where

is the acceleration of the first player

is the acceleration of the second player

is the initial distance between the two players
and where I put a negative sign in front of the acceleration of the second player, since he's moving in the opposite direction of the first player.
The time t at which the two players collide is the time t at which

, therefore:

from whic we find

b) We can use the equation of

to find how far the first player run in t=8.5 s:
Answer:
Water flows through this type of soil.
Explanation:
By definition permeable soil is soil which water and other fluid flow easily through (like sand) If a plant needs drainage the soil will need to flow through the soil easily.
The helium atom is found to contain more particles than the hydrogen atom.
<h3>What is a subparticle?</h3>
An atom is composed of particles and these particles are electrons protons and neutrons. The collective name for these particles is the subatomic particles.
Now we know that the helium atom contains more sub atomic particles than the atom of hydrogen. This is because, the helium atom contains two neutrons and two protons as well as two electrons. On the other hand, the hydrogen atom contains one neutron and one proton as well as one electron.
Thus, the helium atom is found to contain more particles than the hydrogen atom.

Answer:
P = 96 J
Explanation:
Given that,
Weight of the book, W = mg = 8 N
It is placed at a height of 12 m
We need to find the potential energy of the book. The potential energy of an object is given by the formula as follows :
E = mgh
mg = Weight

So, the potential energy of the book is 96 J.
