When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.

A small steel wire of diameter 1.0mm is connected to an oscillator and is under a tension of 5.7N . The frequency of the oscilla

kotegsom [21]

Answer:

The power output of the oscillator is 0.350 watt.

Explanation:

Given that,

Diameter = 1.0 mm

Tension = 5.7 N

Frequency = 57.0 Hz

Amplitude = 0.54 cm

We need to calculate the power output of the oscillator

Using formula of the power

$P=\dfrac{1}{2}\times\mu\times\omega^2\times a^2\times v$

Put the value into the formula

$P=\dfrac{1}{2}\times A\times\rho\times\omega^2\times a^2\times\dfrac{\sqrt{T}}{\mu}$

$P=\dfrac{1}{2}\times3.14\times(0.0005)^2\times7850\times(2\times\pi\times57.0)^2\times(0.54\times10^{-2})^2\times\sqrt{\dfrac{5.7}{3.14\times(0.0005)^2\times7850}}$

$P=0.350\ Watt$

Hence, The power output of the oscillator is 0.350 watt.

A chemical process with an e-factor of 1 creates less waste than an e-factor of 25?

morpeh [17]

A chemical process with an e-factor of 1 creates less waste than an e-factor of 25 is True.

<h3>What do you mean by E-factor?</h3>

The actual amount of waste produced during the process—which is referred to as anything other than the targeted product—is known as the E factor. It considers the chemical yield as well as reagents, solvent losses, all process aids, and, in theory, fuel (although this is often difficult to quantify). There is one exception: I often did not include water in the E factor calculation. For instance, only the inorganic salts and organic chemicals present in an aqueous waste stream are taken into account; the water itself is left out. In many instances, the inclusion of water used in the process might result in very high E factors, which can make it challenging to compare processes in a meaningful way.

Two long straight parallel wires seperated by 20cm apart carry current of 20A and 1OA in opposite directions. What is the magnit

kati45 [8]

Answer:

Force is 2 × 10^-4 N

Explanation:

${ \bf{F = \frac{ \gamma_{o} I _{1} I _{2} l}{2\pi r} }}$

F is force

I is current

r is separation distance

gamma is a constant

l is wire length

$F = \frac{(4\pi \times {10}^{ - 7}) \times (20) \times (10) \times 1 }{2\pi \times 0.2} \\ \\ F = 2 \times {10}^{ - 4} \: \: newtons$

Which question could Not be answered by using the scientific method?

Alchen [17]

For the first question you could devise a way to test the question to find the answer. You could create a sample of black cats, a sample of white cats, and a control sample of a both black and white cats.
You would measure how much the cats eat each day. The study could be repeated or reviewed by your peers. 

For the second question, there is currently no way to sample a person's thoughts, but even if there was a way, there would be no way to repeat the moment. It is not testable and not repeatable and thus cannot use the scientific method. 

Calories can be measured and compared. 

The tide can be observed until someone hypothesizes the right testable notion to determine the answer.
