The decimal place accuracy of a number is the number of digits to the right of the decimal point. ... If there is no decimal point, it is understood to be after the last digit on the right and there is no place (zero place) accuracy. The significant digits of a number are those digits that are most accurate.

A 6.0-Ï‰ and a 12-Ï‰ resistor are connected in parallel across an ideal 36-v battery. What power is dissipated by the 6.0-Ï‰ res

Elena L [17]

Answer:

P = 216 Watts

Explanation:

Given that,

Resistance 1, $R_1=6\ \Omega$

Resistance 2, $R_2=12\ \Omega$

Voltage, V = 36 V

We need to find the power dissipated by the 6 ohms resistor. In case of parallel circuit, voltage throughout the circuit is same while the current is different.

Firstly, lets find current of the 6 ohms resistor such that,

V = IR

$I=\dfrac{V}{R}\\\\I=\dfrac{36}{6}\\\\I=6\ A$

The power dissipated by 6 ohms resistor is given by :

$P=I^2R$

$P=6^2\times 6\\\\P=216\ W$

So, the power dissipated across 6 ohm resistor is 126 watts.

1. Massive amounts of destructive energy are released when a nuclear fission bomb explodes. Where does that energy come from?

kipiarov [429]

Answer: A. A chain reaction occurs when uranium atoms split, releasing nuclear energy.

Explanation: Nuclear fission reactions are those nuclear reactions in which heavier nuclei splits into two or more lighter nuclei. In these reactions, neutrons are released with a large amount of energy.

General equation for nuclear fission reactions is given by

$_{92}^{235}\textrm{U}+_0^1n\rightarrow _{98}^{236}\textrm{U}\rightarrow _{56}^{139}\textrm{Ba}+_{36}^{94}\textrm{Kr}+3_0^1n$

The released 3 neutrons further react with remaining uranium atoms and thus a chain reaction sets up.
