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

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

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

$P_r = 0.878$

In what fundamental way did the work of Galileo differ from his predecessors who had thought about the sky?

kompoz [17]

Answer: The correct answer is:

Galileo used instruments and experiments to show him what nature was doing, instead of relying on pure logic

Explanation:

Galileo can be considered as one of the precursors of experimentation and the scientific method. A method that doesn't rely on "common sense" and rationalization and logic, but instead is fuelled by a disposition of skepticism and rather makes claims about reality based on experimentation and empirical data shows.

Galileo differed from his predecessors because he actually used and developed instruments and method to reliable measure and observe what nature was doing, instead of relying on pure logic.

A rock falls off a cliff. How fast is the rock traveling vertically two seconds later?

Vikentia [17]

The rock it traveling really, really fast.
It is hard to exactly determine how fast bc u need the height of the cliff and how big the rock is.
Hope this helps and can I get brainliest answer!

A. Compare solids, liquids, and gases in terms of the way their volumes change (or don't change) when placed into different cont

svet-max [94.6K]

a) Solids keep shape, liquids take shape of containers but don't spill, gases take container's shape and spill out

b) if you heat gas, speed of its molecules will increase and they'll push the container's walls stronger, so the pressure will increase when the container heated

c) Heat flows from warmer to colder bodies

d) For monatomic gases it's U=1.5nRT only, molecular gas has bonds between atoms so total internal energy increases

e) Of gases

f) $v=\sqrt{\frac{3RT}{M}}=321$ m/s
