Answer:

Explanation:
From the question we are told that:
Mass of pulley 
Radius 
Mass of block A 
Mass of block B 
Spring constant
Generally the equation for Torque is mathematically given by
Since 
At mass A

At mass B

At Pulley


Therefore the equation for total force F
At mass A+At mass B+At Pulley




Since From above equation

Therefore



Generally the equation for frequency is mathematically given by

Answer:
(A) 654.545 Kw
(B) 
Explanation:
We have given resistance of the toaster 
Resistance of nichrome heating element 
Both the resistances are connected in series so same current will flow through the circuit
Potential difference across the toaster V = 120 volt
So current 
(a) Power dissipated in toaster 
(B) Power dissipated in heating element

Answer:
v₁ = 9 m/s
Explanation:
Here, we can use the continuity equation, as follows:

where,
A₁ = Cross-sectional area of the wider section = 48 cm²
A₂ = Cross-sectional area of the constriction = 12 cm²
v₁ = speed of flow in wider section = ?
v₂ = speed flow in constriction = 36 m/s
Therefore,

<u>v₁ = 9 m/s</u>
