AnswerThe current through a toaster connected to a 120-V source is 8.0 A. What power is given off by the toaster? p= 8.0 A : 120V (p=960 W Page 2 7. The resistance of an electric stove eleinent at operating temperature is 11 12.

hope this helps =)
<span>Astatine is the limited element found in the Earth's crust. This element is the rarest one found in the crust and it is radioactive. It is named after the Greek word "astatos" which means unstable. The first acknowledgement of it, came in 1940, which was when it was declared.</span>
The answer is; 2.
To balance a chemical equation, the moles on one side of the equation has to be the same as that on the other side. This ensures that the law of conservation is observed because matter or energy can't be created or destroyed but can only be transformed from one form to another.
In this equation, putting 2 in front of NaCl ensures that there are 2 moles of Na and CL just as there are 2 moles of Na and CL in the reactants side.
Answer:
a) its frequency
Explanation:
The color of visible light depends only on its frequency, not on the amplitude. In fact, the visible light spectrum can be classified into different colors according to the different frequencies:
Violet: 680-790 THz
Blue: 620-680 THz
Cyan: 600-620 THz
Green: 530-600 THz
Yellow: 510-530 THz
Orange: 480-510 THz
Red: 405-480 THz
And the color of the light has nothing to do with the amplitude of the wave. Therefore, the correct answer is
a) its frequency
Answer:
366.6J
Explanation:
We only need to apply conservative linear momentum, making v the initial speed of pigeon, so
Solving for v,
<em>The energy lost we can calculate with </em>
