Winds are turned to the left in the Southern Hemisphere.<br><br> true or false

Nutka1998 [239]

Answer:

true

Explanation:

The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected. In the Northern Hemisphere, wind and currents are deflected toward the right, in the Southern Hemisphere they are deflected to the left.

A car battery with a 12 V emf and an internal resistance of 0.037 Ω is being charged with a current of 45 A. Note that in this p

matrenka [14]

Answer:

Part a)

$V = 13.665 V$

Part b)

$P = 74.9 Watt$

Part c)

$P = 540 watt$

Part d)

$P_r = 0.878$

Explanation:

Part a)

As we know that the during the charging process of the battery the terminal voltage of the cell is given as

$V = E + iR$

$V = 12 + (0.037)(45)$

$V = 13.665 V$

Part b)

Thermal energy dissipated in the battery is due to its internal resistance

so it is given as

$P = i^2 R$

here we have

$P = 45^2 (0.037)$

$P = 74.9 Watt$

Part c)

rate of energy conversion in the in the battery is given as

$P = E. i$

$P = 12(45)$

$P = 540 watt$

Part d)

percentage of the power conversion is given as

$Pr = \frac{P_{out}}{P_{total}}$

$Pr = \frac{540}{540 + 74.9}$

$P_r = 0.878$
