The momentum of an ostrich is calculated to be 5,400 kg*km / hr Its mass is known to be 120 kg. Was the ostrich moving or standi
Dmitry [639]

The correct answer to the question is : The ostrich is motion.

EXPLANATION:

As per the question, the momentum of ostrich P = 5400 Kg. Km/hr.

The mass of the ostrich m = 120 Kg.

The momentum of a body is defined as the product of mass with velocity.

Mathematically P = mv.

The velocity of the ostrich v is calculated as -

                                           v = \frac{P}{m}

                                              = \frac{5400}{120}\ Km/hr

                                              = 45 Km/hr

Hence, the ostrich is in motion as it is moving with a velocity of 45 Km/hr.

A baseball approaches home plate at a speed of 44.0 m/s, moving horizontally just before being hit by a bat. The batter hits a p
Luda [366]

Explanation:

It is given that,

Speed of the baseball, u = 44 m/s

Speed of the baseball, v = 53 m/s

Mass of the ball, m = 145 g = 0.145 kg

Time of contact between the ball and the bat, t = 2.2 ms = 0.0022 s

F=ma

F=\dfrac{mv}{t}

F_1=\dfrac{0.145\ kg\times 44\ m/s}{0.0022\ s}

F₁ = 2900 N...........(1)

F=ma

F=\dfrac{mv}{t}

F_2=\dfrac{0.145\ kg\times 53\ m/s}{0.0022\ s}

F₂ = 3493.18 N.........(2)

In average vector form force is given by :

F=F_1+F_2

F=(2900i+(-3493.18)\ N

F=(2900i-3493.18j)\ N

Hence, this is the required solution.

A wave of amplitude 20mm has intensity Ix. Another wave of the same frequency but of amplitude 5mm has an intensity Iy.
Alexeev081 [22]

Answer:

(C) 16

Explanation:

Given:

The amplitude of first wave (s₁) = 20 mm

The amplitude of second wave (s₂) = 5 mm

Intensity of first wave = Iₓ

Intensity of second wave = I_y

The intensity associated with a wave depends on the amplitude of the wave.

The intensity (I) is directly proportional to the square of the amplitude (s) of the wave and is expressed as:

I=ks^2\\Where\ k\to constant\ of\ proportionality

Now, the intensities of the two waves are given as:

I_x=ks_1^2=k(20)^2\\\\I_y=ks_2^2=k(5)^2

Dividing both the intensities, we get:

\frac{I_x}{I_y}=\frac{k(20)^2}{k(5)^2}\\\\\frac{I_x}{I_y}=\frac{400}{25}\\\\\frac{I_x}{I_y}=16

Therefore, the option (C) is correct.
