Charge is moving through a wire. An amount of charge Q moves past a particular spot in the wire in an amount of time t to produc

Blababa [14]

We will apply the concept related to the current change given in the same problem. We will divide both currents into two states: the new current and the old current. As the current is the change of the load in a certain time, we will have that the old current is,

$I_{old} = \frac{dq}{dt}$

If it takes 5 times more time, then we will have the new current is,

$I_{new} = \frac{dq}{5dt}$

$I_{new} = \frac{1}{5}(\frac{dq}{dt})$

Replacing the given value of the old current we will have to,

$I_{new} = \frac{I_{old}}{5}$

Therefore the new current will be $\frac{1}{5}$ the old current.

Which statements accurately describe the shape of Earth’s orbit around the Sun? Check all that apply.

damaskus [11]

<span>The Earth’s orbit is a nearly circular ellipse.
</span><span>The Sun is located at one of the two focal points.</span>

The Earth moves around the Sun in an orbit that is almost but not quite circular. As Kepler proved in the seventeenth century, the orbit is actually an ellipse. A parameter called the eccentricity (e) defines the degree of departure from a circle. A value of e=0 would indicate a circle whereas a value of e=0.9 would indicate a very elongated ellipse. The eccentricity of the Earth's orbit is currently e=0.0167.

A bike is traveling to the left with the speed of 27 m/s when the rider slams on the brakes. The bike skids for 41.5 m with the

Darina [25.2K]

The acceleration of the bike is equal to $8.78\frac{m}{s^{2}}$ opposing the movement (to the right).

Why?

Since after the rider slams the brakes, the bike came to a stop, we know that the acceleration is opposite to the velocity/movement.

We can use the following equation to calculate the acceleration:

$v_{f}^{2}=v_{o}^{2}+2*a*d$

So, substituting, we have: (let's consider negative to the left and positive to the right)

$0=(-27\frac{m}{s} )^{2}+2*a*41.5m\\\\0=729\frac{m^{2} }{s^{2} }+83*a\\\\a=\frac{-729\frac{m^{2}}{s^{2}}}{83m}=-8.78\frac{m}{s^{2}}$

The negative sign means that the acceleration's direction is opposite to the movement.

Hence, we have that the acceleration is equal to $8.78\frac{m}{s^{2}}$ opposing the movement (to the right).

Have a nice day!
