Answer:
3.16 × W/
Explanation:
β(dB)=10 ×
=
W/
β=55 dB
Therefore plugging into the equation the values,
55=10 })[/tex]
5.5= })[/tex]
=
316227.76×= I
I= 3.16 × W/
Answer:
The correct answer is
a) 1, 2, 3
Explanation:
In rolling down an inclined plane, the potential energy is Transferred to both linear and rotational kinetic energy thus
PE = KE or mgh = 1/2×m×v² + 1/2×I×ω²
The transformation equation fom potential to kinetic energy is =
m×g×h =
=
=
=
Therefore the order is with increasing rotational kinetic energy hence
the first is the sphere 1 followed by the disc 2 then the hoop 3
the correct order is a, 1, 2, 3
