Answer:
See explanation
Explanation:
According to Newton's second law, the rate of change of momentum is proportional to the impressed force.
Mathematically;
Ft = mv - mu
Where;
F = Force
t = time
m= mass
v = final velocity
u = initial velocity
Since the mass is the same, the equation reduces to;
Ft = m(v-u)
So
F= m(v-u)/t
but
(v-u)/t = acceleration (a)
F = ma
a = F/m
Since the mass is the same because Sarah is the same size as i am but she pulls with a greater force, it follows that i will be the one in the wagon when the wagon has the greatest acceleration because the force that Sarah applies when pulling me is greater than the force i will apply when pulling her.

Explanation:
i havnt done this in school yet but my idea is that shaking the bottle makes the co2 float to the top, then when you open it the presure will release and the co2 with rush out
Answer:
Brass is an alloy, and either a "solid solution".
Alloys in general may be solid solutions or they simply be mixtures

<h2>Hope it Helps you!! </h2>
For us to accurately determine what compound
this is, additional info must be given. However I can suggest two compounds
which have molecular mass of about 30.07 g/mol.
1. It could be NO or nitric oxide.
The molecular mass is 16 + 14= 30 g/mol
But if we search the exact weight, it is 30.01 g/mol
2. It could also be (CH3)2 or ethane.
The molecular mass is 2*12+ 6*1= 30 g/mol
But if we search the exact weight, it
is 30.07 g/mol.
<span>So we could say it more likely to to be (CH3)2 </span>
Explanation:
since it has been accelerated to 5℅ of the sleec of light then
v= 5/100 × (3× 10^8)
after getting velocity you'll substitute the values in the formula
de Broglie wavelength= h/mv
don't forget to change the grams in mass to kg
aorry I don't hav my calc with me
