Answer:
Explanation:
Every chemical reaction can be represented by simple chemical equations that shows how compounds are combining to give some products.
Such reactions are usually made up of:
Reactants on the left hand side
Products on the right hand side
Reactants → Products
In this given problem;
Reactants are : Magnesium fluoride = MgF₂
Iodine in form of Iodide = I₂
Product : Magnesium iodide = MgI₂
MgF₂ + I₂ → MgI₂ + F₂
For Pascal's law, the pressure is transmitted with equal intensity to every part of the fluid:
which becomes
where
is the force on the first piston
is the area of the first piston
is the force on the second piston
is the area of the second piston
If we rearrange the equation and we use these data, we can find the intensity of the force on the second piston:
It should be A.
A ball bouncing is moving so if it’s moving that means it has kinetic energy. It also has potential energy because when it hits the floor it kind of stops so it has potential.

Answer:
Secondary structure
The secondary structure arises from the hydrogen bonds formed between atoms of the polypeptide backbone. The hydrogen bonds form between the partially negative oxygen atom and the partially positive nitrogen atom
Answer:
r = 0.5 m
Explanation:
First we find the angular speed of the ball by using its period:
ω = θ/t
For the time period:
ω = angular speed = ?
θ = angular displacement = 2π rad
t = time period = 0.5 s
Therefore,
ω = 2π rad/0.5 s
ω = 12.56 rad/s
Now, for the radius:
v = rω
r = v/ω
where,
v = linear speed = 6.29 m/s
r = radius = ?
r = (6.29 m/s)/(12.56 rad/s)
<u>r = 0.5 m</u>
