3 0

Answer:

11, 760 Pa.

Explanation:

By applying formula P= pgh, where P is pressure, p is density, g is gravitational acceleration (9.8 m\s2) and h is height of water level. Putting values in the formula, you can have the correct answer.

A cricket player hit a ball of mass 250 g moving with velocity of 6 m/sec. if ball move with a velocity of 9 m/sec in opposite d
PolarNik [594]

Explanation:

Given that,

Mass of a ball, m = 250 g = 0.25 kg

Initial velocity of the ball, u = 6 m/s

Final velocity of the ball, v = -9 m/s

(a) Impulse of the system is given by :

Impulse = change in momentum

J = m(v-u)

J = 0.25(-9-6)

= -3.75 kg-m/s

(b) Impulse = Ft

If t = 0.5 min = 30 s

So,

F=\dfrac{J}{t}\\\\F=\dfrac{-3.75}{30}\\\\F=-0.125\ N

So, impulse of the system is -3.75 kg-m/s and the force is -0.125 N.

A hiker walks 4.5 km at an angle of 45° north of west. Then the hiker walks 4.5 km south. What is the magnitude,angle, and direc
maksim [4K]

Answer:

Magnitude of the hiker's total  displacement = 3.5 km

Angle and direction of the hiker's total  displacement = 22 degree south of west

Explanation:

The first Displacement in vector form is

s_1 = -4.5 cos 45i +4.5 sin 45j

= -3.182i + 3.182j

The second Displacement in vector form is  

s_2= -4.5j

The total displacement is ,

s = s_1+ s_2

= -3.182i + 3.182j - 4.5j

=-3.182i-1.318j

The magnitude of the displacement is,

s= \sqrt{(-3.182)^2 + (-1.318)^2\\

s=\sqrt{10.125+1.7371}

s=\sqrt{11.862}

s= 3.444

The direction is,

\theta = tan^{-1}(\frac{1.318}{3.182})

\theta = tan^{-1}(0.4142)

\theta = 22.49^{\circ}
