Answer:
20.28 oz
Step-by-step explanation:
30% is the same as 0.30
Multiply 15.6 x .30, and you get 4.68
Then, add 4.68 to 15.6
Hi! The answer would be 5.38.
Answer:
11.2 gallons
Step-by-step explanation:
by multiplying 16 by 0.965 (as it is a 4.5% decrease per year) and then multiplying the answer by 0.965 and so on until done a total of 10 times gets you the answer 11.2 gallons. there is a quicker way to do it but I cannot remember sorry
Answer:
when they are far away from each other they will move at a velocity of v∞/q = 1.84*10⁶ m/(s*C)
Step-by-step explanation:
if we assume that the charges repel according to a Coulomb's law ( we neglect any relativistic effects) , then the force of repulsion is
F rep = k*q*q/r²
where q= charge
k= Coulomb's constant
r= distance
from Newton's second law :
F rep = m*a= m*dv/dt = m*dv/dr * dr/dt = m*v*dv/dr
k*q*q/r² = m*v*dv/dr
k*q*q/(m*r²) = v*dv/dr
(k*q*q/m) ∫ r⁻² dr= ∫v*dv
-2*k*q*q/m*r = v² - v₁²
for r=r₀ , v=0 ,then
-2*k*q*q/m*r₀ = 0 - v₁²
v₁² = 2*k*q*q/m*r₀
v²= -k*q*q/(m*r) + v₁²= 2*k*q*q/m* (1/r₀-1/r)
then
v²= 2*k*q²/m* (1/r₀-1/r)
when the masses are far away from each other r→∞ , 1/r → 0, then
v∞² = 2*k*q²/(m*r₀)
v∞ = √[2*k*q²/(m*r₀)]
since
k= 8.987*10⁹ N·m²/C² , m= 1 mg = 0.001 kg , r₀= 5.3 cm = 0.053 m
v∞/q = √[[2*k/(m*r₀)] = √[2*8.987*10⁹ N·m²/C²/(0.001 kg*0.053 m)] = 1.84*10⁶ m/(s*C)
v∞/q = 1.84*10⁶ m/(s*C)
Answer:
<u>The answer is 112º.</u>
Step-by-step explanation:
We can multiply 34 by 2, considering there's 2 angles that are 34 each. We'd get 68. Subtract 180 - 68, you'd get 112.
<u>Thus, 112º would be your final answer. </u>
Hope this helped!
