What is the definition of visible white light wave (RoyGBive)

1 answer:

5 0

There's no such thing as a wave of white light. Every light wave with
a certain wavelength has some color. White light is a mixture of all
the different wavelengths with all of the different visible colors.
They're ALL there in white light. When they all enter your eye at
the same time, your brain gets the message of brightness with
no particular color, which we call "white light".

Answer:

$-0.25 rad/s^2$

Explanation:

The equivalent of Newton's second law for rotational motions is:

$\tau = I \alpha$

where

$\tau$ is the net torque applied to the object

I is the moment of inertia

$\alpha$ is the angular acceleration

In this problem we have:

$\tau = -12.5 Nm$ (net torque, with a negative sign since it is a friction torque, so it acts in the opposite direction as the motion)

$I=50.0 kg m^2$ is the moment of inertia

Solving for $\alpha$ , we find the angular acceleration:

$\alpha = \frac{\tau}{I}=\frac{-12.5 Nm}{50.0 kg m^2}=-0.25 rad/s^2$

A driven gear with 60 teeth is driven by a driven gear of 30 teeth what is the VR of

noname [10]

Answer:

VR=2

Explanation:

driven=60

driving=30

but VR=driven/driving

VR=60/30

VR=2

hence the velocity ratio VR is 2

Ethan is using a machine to mix cement. The work input is 10 and the work output is 8. What is the efficiency of the

Arturiano [62]

Efficiency or $\eta$ is calculated by formula: $\eta=\frac{W_{output}}{W_{input}}$ where $\eta\leq1$ also efficiency has no unit.
