<u>Answer:</u>
"They stay in place and vibrate" is true about the particles of iron.
<u>Explanation:</u>
The iron in solid state have tiny particles like atoms, molecules and ions which stay in their position and can only vibrate slightly as their arrangement is compact in nature which do not allow them to move all over the place due to strong force of attraction called as "inter-molecular attraction".
While iron in molten form, being semi-solid have more spaces between the particles, therefore they vibrate more than the particles in compact situation of solid state. And definitely the inter-molecular force of attraction is also weaker than in between actual solid iron particles.
Answer:
<h2>
<u>76.36m/s</u></h2>
Explanation:
Step one:
given data
let the mass of the rider be m,=110kg
let the velocity be v=?
let the mass of the car be M,=110kg
let velocity of the car V=6m/s
Step two:
the momentum of an object is given by the expression
P=mv
<em />
Step two:
<em>since the two the bicycle rider must have the same momentum as the car,</em>
<em>then we need to equate their momentum</em>
mv=MV
110*v=1400*6
110v=8400
divide both sides by 110 to find v
v=8400/110
v=76.36m/s
<u>The rider is expected to have a speed of 76.36m/s</u>
the first step would be gathering information , and making sure its correct
Answer:
A) Amplitude
Explanation:
The angular frequency ω = √k/m
maximum acceleration = ω²A ; A is amplitude
frequency of oscillation = ω / 2π
maximum force = m x ω²A
so maximum acceleration ,frequency of oscillation and maximum force
all depend on ω so they will change due to change of mass . Hence amplitude will remain constant.
