A 9.0-V battery is connected to a resistor so that there is a 0.50-A current through the resistor.For how long should the batter

salantis [7]

Answer:

35.6 s

Explanation:

The power through the resistor is given by:

$P=VI$

where V=9.0 V is the voltage and I=0.50 A is the current. Substituting into the formula, we find

$P=(9.0 V)(0.5 A)=4.5 W$

The power is also equal to:

$P=\frac{W}{t}$

where W is the work done while t is the time taken. Since we know the work done, W=160 J, we can re-arrange the equation to find the time taken:

$t=\frac{W}{P}=\frac{160 J}{4.5 W}=35.6 s$

Kepler's laws, satellites motion and weightlessness

Anon25 [30]

Answer:

First Kepler law states that Each planet describes an ellipsoidal motion about the sun as its single focus.

Second Kepler law states that An imaginary line joining a planet to the Sun sweeps out equal areas in equal time intervals.

Third Kepler law states that The squares of period of revolution of the planet around the sun are proportional to the cubes of mean distance between the planet and the sun.

Weightlessness is the condition where the body has zero gravity ( its acceleration is equal to the acceleration due to gravity )

Phantasy [73]

Female flies are the one that are saddle with the responsibility of laying eggs during reproduction. The female usually look for a warm and moist place that have abundance food source for laying the eggs. The eggs laid by by the flies transformed into larva, which is also called maggots and the maggots turn into flies.
