How much work, in Joules. is done when a pressure of 95.000 Pa changes a volume from 15 ma to 43 m2?

gayaneshka [121]

Answer:

-2.66 kJ

Explanation:

At constant pressure, work done is:

W = -P ΔV

W = -(95.000 Pa) (43 m² − 15 m²)

W = -2660 J

W = -2.66 kJ

In a Young's double-slit experiment, light of wavelength 500 nm illuminates two slits which are separated by 1 mm. The separatio

liubo4ka [24]

Answer:

The value is $y = 0.0025 \ m$

Explanation:

From the question we are told that

The wavelength is $\lambda = 500 \ nm$

The distance of separation is $d = 1\ mm = 0.001 \ m$

The distance from the screen is $D = 5 \ m$

Generally the separation between the adjacent bright fringe is mathematically represented as

$y = \frac{D * \lambda }{ d}$

=> $y = \frac{5 * 500 *10^{-9}}{0.001}$

=> $y = 0.0025 \ m$

How much work done when .0080 C is moved through a potential difference of 1.5 V? Use W = qV. A.

grin007 [14]

Answer:

0.012 J

Explanation:

We are given:

q = 0.0080C

Potential difference = 1.5V

W=qV

Substituting the values into the equation:

W=0.0080*1.5= 0.012J
