A. Compute the torque developed by an industrial motor whose ouputis 150kW at an angular speed of 4000 rev/min.
Gnom [1K]

Answer:

A. τ = 358 N.m

B. m = 73kg

C. V = 209.5 m/s

Explanation:

Let's first convert angular speed to rad/s:

ω = 4000 rev/min * 2π / 60 = 419 rad/s

Since Power is P = τ * ω,

τ = P / ω = 358 N.m

For part B: On the hanging weight:

T - m*g = 0

T = m*g

On the drum:

τ = T*R    Replacing the expression for Tension of the rope:

τ = m*g*R

Solving for m:

m = 73 kg

For part C:

V = ω * R = 209.5 m/s

What is the final electron acceptor in noncyclic electron flow?
Phoenix [80]

Answer:

final electron acceptor in noncyclic electron flow is NADP+

Explanation:

solution

in the plant final electron acceptor in noncyclic electron flow is NADP+

because we know here that NADP+ is oxidized by nicotinamide adenine di nucleotide phosphates

and coenzyme that is act as electron transported agent

so as a oxidized substance that act as electron acceptor

so that as non cyclic electron flow final electron acceptor is NADP +
