The piano strings<span> for </span>low notes<span> are heavier, </span>have<span> more inertia, and </span>vibrate<span> at a lower frequency a lower pitch than lighter </span>strings<span> of the same </span>string<span> tension. Loudness involves how hard the keys are struck, which affects the amplitudes of the </span>vibrating strings<span>. the touch sensitivity of the </span>piano<span> distinguishes it from earlier.

Answer:
11.7 s
Explanation:
In this problem, the rocket is moving in a uniform accelerated motion. We have the following data:
d = 223 m, the distance that the sled has to cover
, the acceleration of the rocket
We can use therefore the following SUVAT equation:
where
d is the distance
u = 0 is the initial velocity of the sled (it starts from rest)
t is the time
a is the acceleration
Re-arranging the equation and substituting the numbers, we find the time it takes for the rocket to cross the field:
Answer:
i would describe an ocean current like a pull of the water
Explanation:
water
<span>Among the choices provide, the one statement that is true with regards to a charged atom is C, the number of protons and the number of electrons within the same atom are unequal. A charged atom is called an ion. Atoms are nonpartisan since they have similar quantities of positive and negative charges.</span>
The frequency of oscillation on the frictionless floor is 28 Hz.
<h3>
Frequency of the simple harmonic motion</h3>
The frequency of the oscillation is calculated as follows;
f = (1/2π)(√k/m)
where;
- k is the spring constant
- m is mass of the block
f = (1/2π)(√7580/0.245)
f = 28 Hz
Thus, the frequency of oscillation on the frictionless floor is 28 Hz.
