If you don't wear a helmet and let's say you fell off your bike, you can severely injure your head! But if you DO wear a helmet and you fell off your bike, there's about I predict a 98% chance that you won't injure but sometimes it's 100%
hope this helps!<span />
Answer:
D and compound
Explanation:
because N2 is = to a compound
Answer:
2.62A
Explanation:
Given
V = 0.43 V
I = 3.1 A
Then, V = IR, R = V/I
R = 0.43/3.1
R = 0.14 Ω
The induced emf = dB/dt * A
So that, dB/dt = emf/A
Since dB/dt is constant then Emf/A(circle) = Emf/A square
So Emf (square)/Emf (circle) = A square / A circle
A circle = πr². The perimeter of the square is 2πr which also is the circumference of the square.
Since the perimeter is 2πr, then each side would be πr/2. Thus, the area of the square would be, (πr/2)² = π²r²/4
So A square/Acircle = (π²r²/4) / πr² = π/4 = 0.79
this means that, emf square = emf circle * 0.79
emf square = 0.43*0.79 = 0.34V
I = V/R
I = 0.34/0.13
I = 2.62A
Base on my research is that in order to balance an equation, you need to make sure that both the reactant and the product of the equation is equal. So base on the problem the product has dihydrogen monoxide. So to make sure this equation to be in balanced you need to add coefficients 2 to the oxygen to make it dioxygen on the left side. The balanced equation is now CH4 + 2O2 = CO2 + 2H2O
