Given:
Sample 1:
Chloroform is 
12 g Carbon
1.01 g Hydrogen
106.4 g Cl
Sample 2:
30.0 g of Carbon
Solution:
mass of chloroform from sample 1:
12 + 1.01 +106.4 =119.41 g
Now, for the total mass of chloroform in sample 2:
mass of chloroform 
mass of chloroform = 119.41 
= 298.53 g
Answer:
a

the plane is not going up and the rest are true
Answer:
<em>7.2 N</em>
Explanation:
length of wire L = 240 m
current I = 500 A
field strength B = 3 x 10^-5 T
magnetic force on a current carrying conductor F is given as
F = BILsin∅
The wires are perpendicular with field therefore sin∅ = sin 90° = 1
therefore,
F = BIL = 3 x 10^-5 X 500 X 240 = 3.6 N
<em>If the wire exists between this two transmission lines, then total magnetic force on the wire = 2 x 3.6 = 7.2 N</em>
Answer:
B. 75V
Explanation:
The formula for Voltage across and Inductor is given as:
Vr.m.s = Ir.m.s × XL
Where
Ir.m.s : Current across the inductor
XL = 2πFL
In the question we were given values
Ir.m.s = 0.20A
F = 750Hz
L = Inductance = 0.080H
Vr.m.s = 0.20 × ( 2 × π× 750Hz × 0.080H)
Vr.m.s= 0.20 × 376.99111843
Vr.m.s = 75.389223686volts
Approximately = 75volts
Therefore, the voltage across the inductor is 75 volts.
