If your mass is 50 kg (you weigh 110 pounds), and the mass of the refrigerator
is 100 kg (it weighs 220 pounds), and you're standing so that the center of
the frig and the center of you are 1 meter apart (about 3 feet), then the force
of gravity between you and the frig is about 0.0000012 ounce. That's why.
Concept: Dynamic Equilibrium: At dynamic equilibrium, the rate of reactants and the rate of products are almost equal. This means the reactants are converted into products and products are converted to reactants at an equal and constant rate. The equilibrium always tells the state of equal, opposite rates, not equal concentrations. So, it will seem like nothing is happening. Dynamic equilibrium can only happen in a closed system at a constant temperature.
Explanation: As per Le Chatelier's Principle, when we open the nozzle of the right tank, the amount of water in the right tank decreases because both the tanks are connected by a pipe. To counter this change water flows in from the left tank so the dynamic equilibrium will be established.
We actually cant, really. Black Holes are really very powerful and don't just happen in some random place in the cosmos. We have got shots of Black holes that you cannot even see, but all the other big black holes that look like something straight of a sci-fi movie that look real, are really just photo- shopped. good question. Hope This Helped.
Speed=frequency*wavelength, so frequency=speed/wavelength. frequency=80*0.2
Frequency = 16 Hz
Answer:
3. Silver tarnishes when exposed to air and light
Explanation:
Physical properties are properties that change substances in ways that is visible to a human by using their senses (ie. see, touch, etc)
The rest of the answers are chemical properties, which cannot be seen with the human senses, and requires other special devices or techniques to tell.
-Vibilities
