To protect their young in the nest, peregrine falcons will fly into birds of prey (such as ravens) at high speed. In one such ep

I am Lyosha [343]

Answer:

Part a)

$\theta = 48 degree$

Part b)

$v = 13.45 m/s$

Explanation:

Part a)

mass of the Falcon bird is given as

$m = 600 g$

initial speed of the bird is

$v_i = 20 m/s$

final speed of the bird is given as

$v_f = 5 m/s$ (opposite direction)

So here the impulse given by falcon bird is given as

$I = m(v_f - v_i)$

$I = 0.600(20 + 5)$

$I = 15 kg m/s$

now the final momentum of Raven bird in perpendicular direction is given as

$I = mv_y$

$15 = 1.50 v_y$

$v_y = 10 m/s$

now the change in the angle of the raven bird is given as

$tan\theta = \frac{v_y}{v_x}$

$tan\theta = \frac{10}{9}$

$\theta = 48 degree$

Part b)

Final speed of the raven bird is given as

$v^2 = v_x^2 + v_y^2$

$v^2 = 9^2 + 10^2$

$v = 13.45 m/s$

The greatest ocean depths on the Earth are found in the Marianas Trench near the Philippines. Calculate the pressure (in atm) du

frozen [14]

Answer:

$P = 103867260$ atm

Explanation:

The pressure at the bottom of any liquid column is equal to product of density of the liquid , gravitational acceleration constant (g) and height of the water column

Thus, $P = \rho*g*h$

Substituting the given values, we get -

$P = 1029$ kg/m3 $* 9.8$ m/s^2 $*10.3 *1000$ meters

$P = 103867260$ atm
