Problem 5 You are playing a game where you drop a coin into a water tank and try to land it on a target. You often find this gam
Dvinal [7]

Answer:

Option D: 1.5in in front of the target

Explanation:

The object distance is y= 6in.

Because the surface is flat, the radius of curvature is infinity .

The incident index is n_i=\frac{4}{3} and the transmitted index is n_t= 1.

The single interface equation is \frac{n_i}{y}+\frac{n_t}{y^i}=\frac{n_t-n_i}{r}

Substituting the quantities given in the problem,

\frac{\frac{4}{3}}{6in}+\frac{1}{y^i}= 0

The image distance is then y^i=-\frac{18}{4}in =-4.5in

Therefore, the coin falls 1.5in in front of the target

Tatiana [17]

Translating the first sentence into equation we get, t = k(1/h) where t is time in seconds, k is the constant and h is the horsepower. Substituting the values in the equation we have, 12s = k(1/200) we have a k = 2400 seconds – hp. To get the time at 240 hp we use the equation above and the constant, we get, t = (2400 seconds-hp)(1/240hp) t = 10seconds.

How far apart (in mm) must two point charges of 70.0 nC (typical of static electricity) be to have a force of 1.30 N between the
Sever21 [200]

Answer:r=5.824 mm

Explanation:

Given

Charge q_1=70 nC

q_2=70 nC

Force between them F=1.30 N

Electrostatic Force is given by

F=\frac{kq_1q_2}{r^2}

where q_1 and q_2 are the charge on the Particles

r=distance between them

k=Coulomb\ constant =9\times 10^9 N-m^2/C^2

1.3=\frac{9\times 10^9\times 70\times 70\times 10^{-18}}{r^2}

r^2=\frac{9\times 10^9\times 70\times 70\times 10^{-18}}{1.3}

r=\sqrt{33.923\times 10^{-6}}

r=5.824\times 10^{-3}

r=5.824 mm
