Name two factors that can affect the function of an enzyme

Why is the unit of momentum called derived unit

Mnenie [13.5K]

Answer:

the SI unit of momentum is :- kg.ms-1

and we know that,

kinetic energy = 1/2 mv2

E=p2/2m

p=(2Em)1/2

so the derived units are (J.kg)1/2

Question 6 (2 points)

LenKa [72]

Answer:

A. increase the speed

Explanation:

For you to be able to shorten the time it takes for the care to get to its destination, you must increase the speed because if the distance is the same that means you have to increase your speed.

A large ant is standing on the middle of a circus tightrope that is stretched with tension T_s. The rope has mass per unit lengt

k0ka [10]

Answer:

$A = \frac{g \lambda^2 \mu}{4\pi^2 T_s}$

Explanation:

As we know that the speed of the wave in string is given as

$v = \sqrt{\frac{T_s}{\mu}}$

now we will have

frequency of the wave is given as

$f = \frac{v}{\lambda}$

$f = \frac{1}{\lambda}\sqrt{\frac{T_s}{\mu}}$

now if the ant will feel weightlessness then we will have

$mg = m\omega^2 A$

so we will have

$A = \frac{g}{\omega^2}$

$A = \frac{g}{4\pi^2 f^2}$

$A = \frac{g \lambda^2 \mu}{4\pi^2 T_s}$

When this current is closed which way does the current flow

Anastaziya [24]

Well, Godess, that's not a simple question, and it doesn't have
a simple answer.

When the switch is closed . . .

"Conventional current" flows out of the ' + ' of the battery, through R₁ ,
then through R₂ , then through R₃ . It piles up on the right-hand side of
the capacitor (C). It repels the ' + ' charges on the left side of 'C', and
those flow into the ' - ' side of the battery. So the flow of current through
this series circuit is completely clockwise, around toward the right.

That's the way the first experimenters pictured it, that's the way we still
handle it on paper, and that's the way our ammeters display it.

BUT . . .

About 100 years after we thought that we completely understand electricity,
we discovered that the little tiny things that really move through a wire, and
really carry the electric charge, are the electrons, and they carry NEGATIVE
charge. This turned our whole picture upside down.

But we never changed the picture ! We still do all of our work in terms of
'conventional current'. But the PHYSICAL current ... the actual motion of
charge in the wire ... is all exactly the other way around.

In your drawing ... When the switch is closed, electrons flow out of the
' - ' terminal on the bottom of the battery, and pile up on the left plate of
the 'C'. They repel electrons off of the right-side of 'C', and those then
flow through R₃ , then through R₂ , then through R₁ , and finally into the
' + ' terminal on top of the battery.

Those are the directions of 'conventional' current and 'physical' current
in all circuits.

In the circuit of YOUR picture that you attached, there's more to the story:

Battery current can't flow through a capacitor. Current flows only until
charges are piled up on the two sides of 'C' facing each other, and then
it stops.

Wait a few seconds after you close the switch in the picture, and there is
no longer any current in the loop.

To be very specific and technical about it . . .

-- The instant you close the switch, the current is

(battery voltage) / (R₁ + R₂ + R₃) amperes

but it immediately starts to decrease.

-- Every (C)/((R₁ + R₂ + R₃) seconds after that, the current is

e⁻¹ = about 36.8 %

less than it was that same amount of time ago.

Now, are you glad you asked ?
