Answer:
beacause it's contracts
Explanation:
when using a large bottomed glass the hot water cools that's why is good to use thin bottomed glass
The magnetic field at the center of the circular loop is 3.24 x 10⁻⁴ T.
<h3>Current in the wire</h3>
The current in the wire is calculated as follows;
V = IR
I = V/R
I = 16.7/0.251
I = 66.53 A

<span>The maxima of an equation can be obtained by taking the 1st
derivative of the equation then equate it to 0.</span>The value of N that result in best yield is when dy/dn = 0.
Taking the 1st derivative of
the equation y=(kn)/(9+n^2) :<span>
</span>
By using the quotient
rule the form of the equation is:<span>
y = g(n) / h(n)
where:</span>
g(n) = kn --->
g'(n) = k
<span>
<span>h(n) = 9 + n^2 ---> h'(n) = 2n </span>
dy/dn is defined as:
<span>dy/dn = [h(n) * g'(n) - h'(n) * g(n)] / h(n)^2
dy/dn = [(9 + n^2)(k) - (kn)(2n)] / (9 +
n^2)^2
dy/dn = (9k + kn^2 - 2kn^2) / (9 + n^2)^2
dy/dn = (9k - kn^2) / (9 + n^2)^2
dy/dn = k(9 - n^2) / (9 + n^2)^2
<span>Equate dy/dn = 0, then solve for n
k(9 - n^2) / (9 + n^2)^2 = 0
k(9 - n^2) = 0
9 - n^2 = 0
n^2 = 9
n = sqrt(9)
n = 3

Answer:
-16°C
Explanation:
PV = nRT
V and n are constant.
P / T = P / T
(2 atm + 1 atm) / (266 K) = (1.9 atm + 1 atm) / T
T = 257.1 K
T = -16°C
Ke= 1/2 x m x v^2
Ke= 1/2 x 2.1 x 30^2
Energy = 945 J
