Many people love roller coasters. Some people call them scream machines. They agree that

Alex73 [517]

Answer:

There is some sort of "rollers" on the trail part that is used to make the roller coaster move when it is going up. Then because of that, the speed gets quicker when it drops down, so then it could move for a longer time until it reaches the next arch.

Explanation:

hope this helps :)

Light travels in a straight line because it doesn't usually interact with its medium. When it does it is called refraction.

A 12 kg hanging sculpture is suspended by a 80-cm-long, 6.0 g steel wire. When the wind blows hard, the wire hums at its fundame

Deffense [45]

Answer:

$F=78.3hz$

Explanation:

From the question we are told that:

Mass $m=12$

Length $l=80cm=0.8m$

Linear density $\mu= 6.0g$

Generally the equation for Frequency is mathematically given by

$F=\frac{1}{2l}\sqrt{\frac{T}{K}}$

$F=\frac{1}{2(0.8)}\sqrt{\frac{12*9.8*0.8}{6*10^{-3}}}$

$F=78.3hz$

compare the different ways a musician changes the pitch while playing a stringed instrument or playing a wind instrument

alexdok [17]

(This is from experience so sorry if it's wrong but) When wind instruments are played, sometimes the notes go flat or sharp depending on the speed the player blows air into the instrument as well as the warmth of the air. When playing a string instrument, the pitch can be changed in many ways. For example, when the player places their fingers on the string depending on which part of the tip of the finger you use, the tone of the sound and sometimes the pitch, changes. Looking at the question in a different way, you can change the pitch and the range of notes you can reach on the instrument (both wind and string) by changing the note you tune your instrument to. Hope this helps!!

A baseball with a mass of 0.145 kilograms collides with a bat at a velocity of 44 meters/second. The ball bounces off the bat wi

serious [3.7K]

Impulse, Δp, is the value of the change of the ball's momentum. To recall, we can express momentum, p, as the product of the object's mass and velocity. Mathematically, we have

$p = mv$
$\Delta p = m\Delta v$
$\Delta p = m(v_{final}-v_{initial})$

where m is the object's mass and v is the object's velocity.

Since the ball bounced off opposite to its original direction, initial velocity and final velocity will have opposite signs. And hence, we have

$\Delta p = 0.145(49 - -44) = 0.145(93) = 13.485$

Rounding the values off to three significant figures, we have Δp = 13.5 N·s.

Answer: 13.5 N·s
