The outer radius of the ball = 6.70cm.
<h3>What is Buoyant Force?</h3>
The upward force applied to an object that is fully or partially submerged in a fluid is known as the buoyant force.
Given: Mass of aluminum ball = 
To find: The outer radius of the ball.
Finding:
As Buoyant Force = 
,
The weight of the ball should be equal to the buoyant force since it floats on the water.
That is,
=> 
=> 
Upon substitution of values of 
and g, we get: 
Hence, the outer radius of the ball = 6.70cm

I KNOW that you must have seen this formula before. It gives
the distance covered in a certain time of accelerated motion:
D = 1/2 A T²
Distance covered= (1/2) (Acceleration) (Time squared) .
The question gives us the acceleration and the time.
I've got a weird idea: Let's plug them into the formula. OK ?
Distance = (1/2) (10 m/s²) (10 sec)²
= (5 m/s²) (100 sec²)
= 500 meters .

<span>Use this formula:Wavelength=c/v, where c is the speed of light, and v the frequency.
6.33 X 10^-7=3 X 10^8/v
v=3 X 10^8/6.33 X 10^-7
v=4.74 X 10^14 Hertz,</span>
