Answer:

Hypotenuse, h = 37 meters

Explanation:

In a right angled triangle, the length of legs are 12 meters and 35 meters. We have to find the length of the hypotenuse of a right angled triangle.

It can be calculated using Pythagoras theorem :

(hypotenuse)^2=(base)^2+(perpendicular)^2

So, (hypotenuse)^2=(12)^2+(35)^2

hypotenuse = 37 meters.

Hence, the length of the hypotenuse of a right angled triangle is 37 meters.

The answer is 37 cause the two sides squared and added together equals the hypotenuse squared after that you just find the square root of the answer

A blank is any disturbance that carries energy from one place to another through matter and space.
Eduardwww [97]
<h3>Answer;</h3>

<em>A wave </em>

<em><u>A wave</u></em> is any form of a disturbance that carries energy from one place to another through a matter and space

<h3>Explanation;</h3>
  • Waves carry energy from one point, the source to another point or place. The transmission of a wave may occur through the space or through a material medium.
  • Electromagnetic waves are those waves whose transmissions occurs through the space, they do not require material medium for transmission,for example, radio waves, while mechanical waves are those that require material medium for transmission, for example sound waves.
  • The energy of wave depends on the frequency of the wave and the wavelength of that particular wave.

taurus [48]
This process shows alpha decay so X represents an alpha particle. The characteristic of alpha decay is that the mass number stays constant while the proton number increases.

A rock is projected from the edge of the top of a building with an initial velocity of 21.6 m/s at an angle of 37◦ above the hor
dusya [7]
<h2>Horizontal component of the rock’s velocity when it strikes the ground is 17.25 m/s</h2>

Explanation:

In horizontal direction there is no acceleration or deceleration for a rock projected at an initial angle of 37° off the ground.

So the horizontal component of velocity always remains the same.

Horizontal component of velocity is the cosine component of velocity.

Initial velocity, u = 21.6 m/s

Angle, θ = 37°

Horizontal component of velocity = u cosθ

Horizontal component of velocity = 21.6 cos37

Horizontal component of velocity = 17.25 m/s

Since the horizontal velocity is unaffected, we have

    Horizontal component of the rock’s velocity when it strikes the ground = 17.25 m/s

A pendulum is made of a small sphere of mass 0.250 kg attached to a lightweight string 1.20 m in length. As the pendulum swings
olchik [2.2K]

Answer:

0.833 N

Explanation:

Formula for Kinetic Energy E_k = \frac{mv^2}{2}

Formula for Potential Energy E_p = mgy

First we need to find the vertical distance between the maximum-angle position and the pendulum lowest point:

Using the swinging point as the reference, the vertical distance from the maximum-angle (34 degree) position to the swinging point is:

L * cos(34^o) = 1.2cos(34^o) = 1.2*0.83 = 0.995 \approx 1 m

At the lowest position, pendulum is at string length to the swinging point, which is 1.2 m. Therefore, the vertical distance between the maximum-angle position and the pendulum lowest point would be

y = 1.2 - 1 = 0.2 m.

As the pendulum is traveling from the maximum-angle position to the lowest point position, its potential energy would be converted to the kinetic energy.

By law of energy conservation:

E_k = E_p

\frac{mv^2}{2} = mgy

v^2 = 2gy

v = \sqrt{2gy}

Substitute g = 10 m/s^2 and y = 0.2 m:

v = \sqrt{2 * 10 * 0.2} = \sqrt{4} = 2 m/s

At lowest point, pendulum would generate centripetal tension force on the string:

F = m\frac{v^2}{L}

We can substitute mass m = 0.25, rotation radius L = 1.2 m and v = 2 m/s:

F = 0.25\frac{2^2}{1.2} = 0.833 N
