If you're swimming underwater and knock two rocks together, you will hear a very loud noise. But if your friend above the water

Svetradugi [14.3K]

Answer:

The air-water interface is an example of boundary. The transmitted portion of the initial wave energy is way smaller than the reflected portion. This makes the boundary wave hard to hear.

When both the source of the sound and your ears are located underwater, the sound is louder because the sound waves can travel directly to your ear.

Explanation:

The air-to-water sound wave transmission is inhibited because more of reflection than transmission of the wave occurs at the boundary. In the end, only about 30% of the sound wave eventually reaches underwater. For sound generated underwater, all the wave energy is transmitted directly to the observer. Sound wave travel faster in water than in air because, the molecules of water are more densely packed together, and hence can easily transmit their vibration to their neighboring molecules, when compared to air.

Two of the angles in a triangle are complementary. The third angle is twice the measure of one of the complementary angles. What

Marrrta [24]

Explanation:

Let the 2 be X and Y.

Z is 3rd angle.

Z=2X

w.k.t Sum of angles in a triangle is 180°

Z+X+Y=180°

2X+90°=180°

2X=90°

=>X=45°

=>Y=90°-45°=45°

=>Z=2X=2(45°)=90°

Hope this helps you.

1. What is the kinetic energy of a 1.75 kg ball travelling at a speed of 54 m/s?

Over [174]

Answer:

We conclude that the kinetic energy of a 1.75 kg ball traveling at a speed of 54 m/s is 2551.5 J.

Explanation:

Given

Mass m = 1.75 kg

Velocity v = 54 m/s

To determine

Kinetic Energy (K.E) = ?

We know that a body can possess energy due to its movement — Kinetic Energy.

Kinetic Energy (K.E) can be determined using the formula

$K.E=\frac{1}{2}mv^2$

where

m is the mass (kg)

v is the velocity (m/s)

K.E is the Kinetic Energy (J)

now substituting m = 1.75, and v = 54 in the formula

$K.E=\frac{1}{2}mv^2$

$K.E=\frac{1}{2}\left(1.75\right)\left(54\right)^2$

$K.E=1458\times 1.75$

$K.E=2551.5$ J

Therefore, the kinetic energy of a 1.75 kg ball traveling at a speed of 54 m/s is 2551.5 J.

A moving object has a kinetic energy of 150 j and a momentum with a magnitude of 30.0 kg•m/s. determine the mass and speed of th

SOVA2 [1]

To determine the answer to this item, we use two (2) equations.

Equation for kinetic energy:
KE = 0.5 mv²

Equation for momentum:
P = mv

From the second equation, we can deduced that,
m = P/v
Substituting the known values from the given above,

m = 30/v

Using this expression in the first equation,

KE = 0.5 mv²; 150 = 0.5(30/v)(v²)

The value of v from the equation is 10 m/s.

The mass is therefore calculated as such,
m = 30/v = 30/10 = 3 kg

Hence, the answers are,

 Mass = 3 kg
 Velocity = 10 m/s
