The difference between the frequencies of the piano key and the tuning fork gives the frequency of the beats.
When the tuning fork is 405 Hz, and no beats are heard, then the piano key is also 405 Hz.
When the piano key is 405 Hz and the tuning fork is 402 Hz, then 405 - 402 = 3 beats are heard.
The piano key is 405 Hz.
Applying Newton's Second Law of Motion, the acceleration of the ball is 16.8 
<u>Given the following data:</u>
- Acceleration due to gravity = 9.8
To find ball's acceleration, we would apply Newton's Second Law of Motion:
First of all, we would determine the net force acting on the ball.
× 
Downward force = 4.9 N
Net force = 8.4 N
Mathematically, Newton's Second Law of Motion is given by this formula;
<em>Acceleration = 16.8 </em><em />
Therefore, the acceleration of the ball is 16.8

Beginning when the bottom of the object first touches the water,
and as it descends and more and more of it goes under, the
buoyant force on it increases during that time.
As soon as the object is completely underwater, it doesn't matter
how deep under it is, the buoyant force on it remains the same.
Answer:
no..
Explanation:
in balanced force it will or in this case u would stay still or u would move at the same speed.. but when u jumps the speed changes..so this is an unbalanced force
hope my ans helps
pls give brainliest to my answer
be sure to follow me
stay safe
have a good day
Answer:
Fb = 941.76 [N]
Explanation:
La fuerza de flotacion se define como el producto de la densidad del liquido por la aceleración gravitacional y por el volumen desplazado
Fb = Ro*g*V
donde:
Fb = fuerza de flotacion [N] (unidades del Newtons)
Ro = densidad del liquido = 1000 [kg/m³]
g = aceleracion gravitacional = 9.81 [m/s²]
V = volumen desplazado = 0.096 [m³]
Reemplazando:
Fb = 1000*9.81*0.096
Fb = 941.76 [N]
