Answer:
156.1 rad/s = 24.8 rev/s
Explanation:
Torque = Momentum of inertial × radial acceleration = Iα
τ = 26.6 N.m
I = 0.162 kg.m²
26.6 = 0.162 × α
α = 164.2 rad/s²
Using equations of motion,
θ = 11.8 rev = 11.8 × 2π = 74.2 rad
w₀ = 0 rad/s (since the grindstone starts from rest)
w = ?
α = 164.2 rad/s²
w² = w₀² + 2(α)(θ)
w² = 0² + (2×164.2)(74.2)
w = 156.1 rad/s = 24.8 rev/s
Hope this Helps!!!
Answer:
the magnitude and the direction of the total magnetic field is 0.4 Am² antiparallel to the area vector
Explanation:
Given that:
The area vector of a square loop has 5 numbers of turns i.e n = 5
each with side length = 0.2 m
Current I = 2 A
uniform magnetic field = 50.0 T
Now; the magnitude of the total magnetic field B is calculated as :
B = IA
where;
I = current
A = area ( n × l²)
B = I ( n × l²)
B = 2 × 5 × 0.2²
B = 0.4 Am²
The direction of the magnetic moment is antiparallel to the area vector;
Hence ; the magnitude and the direction of the total magnetic field is 0.4 Am² antiparallel to the area vector
The answer would be A and I’m pretty sure of thta
Bread is considered to be a heterogeneous mixture. It is a heterogeneous mixture because all of the components that are used to make the bread are physically separate.
