When two identical resistors are connected in series across ideal battery, total power dissipated by them is P. Now both are con

Art [367]

Answer:

4 P

Explanation:

V = IR

when they are in series R = 2 r

when they are in parallel R = 1/2 r

so current will increase by a factor of 4 when they are in parallel

and power used will also increase by a factor of 4 to 4 P

Power = IV when I now becomes 4 I power becomes 4 P

What happens to the density of a fluid as it temperature increases/decreases?

Elan Coil [88]

Let's look at the density of water at 25 deg C and compare that to a higher temperature, 80 deg C. The density decreases from 0.9970 g/mL to 0.9718 as it is heated. This makes sense because, as heat is added to the liquid water, there is greater kinetic energy of the molecules and there are also more vibrations of the water molecules. Together these mean that each H2O unit in liquid water takes up more space as the temperature increases.

Which is a correct representation of .000025 in scientific notation?

lidiya [134]

0.000025 → 2.5 × 10⁻⁵ → 2.5E-5

<h3>Further explanation</h3>

Scientific notation represents the precise way scientists handle exceptionally abundant digits or extremely inadequate numbers in the product of a decimal form of number and powers of ten. Put differently, such numbers can be rewritten as a simple number multiplied by 10 raised to a certain exponent or power. It is a system for expressing extremely broad or exceedingly narrow digits compactly.

Scientific notation should be in the form of

$\boxed{ \ a \times 10^n \ }$

where

$\boxed{ \ 1 \leq a \ < 10 \ }$

The number 'a' is called 'mantissa' and 'n' the order of magnitude.

From the key question that is being asked, we face the standard form of 0.000025.

$\boxed{ \ 0.000025 = \frac{25}{1,000,000} \ }$

The coefficient (or mantissa), i.e. 25, is still outside of 1 ≤ a < 10. Both the numerator and denominator are divided by 10.

$\boxed{ \ 0.000025 = \frac{2.5}{100,000} \ }$

The denominator consists precisely of five zero digits.

Hence, 0,000025 is written in scientific notation as $\boxed{\boxed{ \ 2.5 \times 10^{-5} \ or \ 2.5E - 5 \ }}$

The inverse of scientific notation is the standard form. To promptly change scientific notation into standard form, we reverse the process, move the decimal point to the right or left. This expanded form is called the standard form.

<u>A notable example:</u>

$\boxed{ \ 3.0 \times 10^{8} \ Hz \ \rightarrow 300,000,000 \ Hz \ or \ 300 \ MHz}$
