Deceleration—the ability to slow down and control force production—is often ignored during training; but deceleration technique is critical for most sports. Speed is often the factor that separates the elite from the average athlete. Credit source is stack.com have a nice day! I told you it was from the internet in case you couldn’t use the internet Hope this helped :)!

Which accounts for an increase in the temperature of a gas that is kept a constant volume

oksian1 [2.3K]

Answer:

An increase in pressure

Explanation:

The ideal gas law states that:

$pV=nRT$

where

p is the gas pressure

V is the volume

n is the number of moles

R is the gas constant

T is the temperature of the gas

in the equation, n and R are constant. For a gas kept at constant volume, V is constant as well. Therefore, from the formula we see that if the temperature (T) is increase, the pressure (p) must increase as well.

When verifying Kirchhoff's rules, you measured: (a) temperature (b) resistance (c) time (d) current

Nadya [2.5K]

Answer:

option D

Explanation:

The correct answer is option D

When verifying Kirchhoff's law we measure current.

Kirchhoff's law deal with current and potential difference.

This law was first described by the German Scientist Gustav Kirchhoff.

Kirchhoff's law stated the current arriving at the node is equal to the current moving out of the node.

A satellite moves in a circular orbit at a constant speed v0 around Earth at a distance R from its center. The force exerted on

postnew [5]

Answer:

vT = v0/3

Explanation:

The gravitational force on the satellite with speed v0 at distance R is F = GMm/R². This is also equal to the centripetal force on the satellite F' = m(v0)²/R

Since F = F0 = F'

GMm/R² = m(v0)²/R

GM = (v0)²R (1)

Also, he gravitational force on the satellite with speed vT at distance 3R is F1 = GMm/(3R)² = GMm/27R². This is also equal to the centripetal force on the satellite at 3R is F" = m(vT)²/3R

Since F1 = F'

GMm/27R² = m(vT)²/3R

GM = 27(vT)²R/3

GM = 9(vT)²R (2)

Equating (1) and (2),

(v0)²R = 9(vT)²R

dividing through by R, we have

9(vT)² = (v0)²

dividing through by 9, we have

(vT)² = (v0)²/9

taking square-root of both sides,

vT = v0/3

If the current direction is reversed in one of the strips, the magnetic field in a point A located outside the space between the

serious [3.7K]

Answer:

Twice the initial value

Explanation:

Let the current be = I

the width of the conducting strips be = a

We know that magnetic field between two plates is given by

$B=\frac{\mu_0 I}{2\pi r}$

If the direction of this magnetic field is same between the two plates, then

$B=\frac{\mu_0 I}{2\pi r} - \frac{\mu_0 I}{2\pi r}$

= 0

And when the currents runs opposite at each plate, then

$B=\frac{\mu_0 I}{2\pi r} + \frac{\mu_0 I}{2\pi r}$

$2 \times B_{initial}$

Hence the magnetic field will be twice the initial value of the magnetic field that runs between the plates.
