andre [41]

The related concepts to solve this problem is the Glide Ratio. This can be defined as the product between the height of fall and the lift-to-drag ratio. Mathematically, this expression can be written as,

$R = h (\frac{L}{D})_{max}$

Replacing,

$R = 5000ft (7.7)$

$R = 38500ft$

Converting this units to miles.

$R = 38500ft (\frac{1mile}{5280ft})$

$R = 7.2916miles$

Therefore the glide in terms of distance measured along the ground is 7.2916miles

When a potential difference of 10 V is placed across a certain solid cylindrical resistor, the current through it is 2 A. If the

DaniilM [7]

Answer:

Current would decrease 9 times.

Explanation:

Assume all others (potential difference U, resistivity ρ, and length L) are the same, only change in the diameter, we would have the following ratio

$\frac{I_1}{I_2} = \frac{U/R_1}{U/R_2} = \frac{U}{U}\frac{R_2}{R_1} = \frac{\rho L/A_2}{\rho L / A_1} = \frac{\rho L}{\rho L}\frac{A_1}{A_2} = \frac{\pi d_1^2/4}{\pi d_2^2/4} = \frac{4\pi}{4\pi}\left(\frac{d_1}{d_2}\right)^2 = 3^2 = 9$

$I_2 = I_1/9$

So the current would decrease 9 times.

An unmarked police car traveling a constant 95.0 km/h is passed by a speeder traveling 110 km/h . Precisely 2.00 s after the spe

Nonamiya [84]

Answer:

So police car will overtake the speeder after 5.64 s

Explanation:

Initially the distance between police car and the speeder when police car is about to accelerate

$d = (v_1 - v_2)t$

$v_1 = 110 km/h = 110 \times \frac{1000}{3600}m/s = 30.55 m/s$

$v_2 = 95 km/h = 95 \times \frac{1000}{3600}m/s = 26.39 m/s$

$d = (30.55-26.39)(2) = 8.32 m$

now we have

now velocity of police with respect to speeder is given as

$v_r = v_2 - v_1 = 26.39 - 30.55 = -4.17 m/s$

relative acceleration of police car with respect to speeder

$a_r = a = 2 m/s^2$

now the time taken to cover the distance between police car and speeder is given as

$d = v_i t + \frac{1}{2}at^2$

$8.32 = -4.17 t + \frac{1}{2}(2)(t^2)$

$t^2 -4.17 t - 8.32 = 0$

$t = 5.64 s$
