Answer:

Explanation:

The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger (dilated) or smaller (constricted).

Answer:

Explanation:

The iris has special muscles that are constantly contracting and expanding to adapt to the amount of light entering your eyes. That's why your iris dialates when you're in the dark, its becomes larger to adapt to the low lighting so you are able to see better

An initially uncharged 4.07 μF capacitor and a 7.71 k Ω resistor are connected in series to a 1.50 V battery that has negligible

lawyer [7]

Answer:

I₀ = 0.2 mA

Explanation:

Just after being connected, as the voltage between plates of a capacitor can't change instantanously, the initial voltage through the capacitor must be zero, so it presents like a short to the battery.
So, in these circumstances, as the battery only "sees"a resistor, the initial current can be found applying Ohm's law to the resistor, as follows:

$V = I_{0}*R \\\\ I_{0} = \frac{V}{R} = \frac{1.50V}{7.71e3\Omega} = 0.2 mA$

The initial current (that will be diminishing as the capacitor charges), is 0.2 mA.

A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 30.0 min

schepotkina [342]

Answer:

Average speed of the trip = 52.9 km/h

Distance between initial pairs of cities (start to end) = 70.0 km

Explanation:

Since distance = speed × time

If she drives 30.0 min at 80.0 km/h

Distance covered = (30/60) × 80 = 40.0 km

Again she drives 45.0 min at 40 km/h

Distance covered = (45/60) × 40 = 30.0 km

Again she drives 12.0 min at 100 km/h

Distance covered = (12/60) × 100 = 20.0 km

Total distance covered = 40.0 + 30.0 + 20.0

= 90.0 km

Total time spent = 30.0 + 45.0 + 12.0 +15.0

= 102 min

Average speed for the trip = Total distance covered/total time spent

= 90/(102/60)

= 52.9 km/h

Distance between initial cities will be between the start of one city to the end of another

Between the first pairs = 40.0 + 30.0 = 70.0 km

Between the second pairs = 30.0 + 20.0 = 50.0 km
