A watt is a unit of electrical power and is equal to one joule per second (1 watt = 1 J s-1). How many hours can a calculator drawing 2.0 × 10-3 watt can be operated by a mercury battery having a cell potential equal to 1.34 V with a mass of 0.22 g of HgO available at the cathode? The cell reaction is HgO(s) + Zn(s) → ZnO(s) + Hg(l)
If 500 J of work are required to carry a charged particle between two points with a potential difference of 40V, the magnitude of the charge on the particle is: a) 0.040 C b) 12.5 C c) 20C D) cannot be computed unless the path is give e) none of thes
If 500 J of work are required to carry a charged particle between two points with a potential difference of 40V, the magnitude of the charge on the particle is: a) 0.040 C b) 12.5 C c) 20C D) cannot be computed unless the path is give e) none of these My solution: I used the equation V=W/q inorder to solve for the charge. I plugged in the numbers to get 40= (500)/X. The answer I got was .08. According...

3. In a second-order phase transition, there is no difference in entropy or volume between the two phases and therefore the Clausius-Clapeyron equation cannot be applied. Two Ehrenfest equations can, however, be found. They follow from the the equality in entropy or volume across the phase transition, and they relate dp/dT to differences in α and C, or K between the two phases (a) By setting dSdS2, find dp/dT in terms of the differences in a and Cp between the...

The power of the microwave can be calculated as follows: Power=Work Time Work is measured in joules (I) and time is measured in seconds (s), so power is expressed in joules per second (J/s) and also known as the watt (W). For example, assume that a microwave oven does 24,000 joules of work in 30 seconds. Then the power of the microwave is 800 J/s, or 800 W. Write a...

QUESTION 10 Power, P, is defined as the rate at which work, W, is done, or the work divided by the time, t, over which that work occurs: P = W / t. Starting from rest, at the bottom of a flight of stairs, what is the power output for a person of mass 55 kg who runs up a flight of stairs of height 3.0 m and reaches the top of the stairs, in a time of 3.0 s,...

A watt is a unit of energy per unit time, and one watt (W) is equal to one joule per second (1 J s). A 80.0- W incandescent light bulb produces about 4.00% of its energy as visible light. Assuming that the light has an average wavelength of 510.0 nm, calculate how many such photons are emitted per second by a 80.0-W incandescent light bulb Number 1.03 x 1019 photons/s
what are the similarities and differences between an arithmetic sequence and a linear equation
what are the similarities and differences between an arithmetic sequence and a linear equation?ok i know that arithmetic sequence is a sequence of real numbers for which each term is the previous term plus a constant (called the common difference). For example, starting with 1 and using a common difference of 4 we get the finite arithmetic sequence: 1, 5, 9, 13, 17, 21; and also the inifinite sequence 1, 5, 9, 13, 17, 21, 25, 29, . . .,...
