Answer:
v = 0.999981c m/s
Explanation:
Using the time dilation equation
T = stationary time = 100 years
T₀ = 11/12 years = 0.917 years
v = speed of travel in the space = ?
c = speed of light = 3 * 10⁸ m/s
v = 299987395.57 m/s
v = 2.99 * 10⁸ m/s
v = 0.999981c m/s
Magnets with the same polarity (N-N or S-S) repel one another along the same direction. This agrees to the common rule that like poles repel and unlike poles attract. Hope this answers the question. Have a nice day. Feel free to ask more questions.
Answer:
3
Explanation:
You must first make sure the equation is balanced. This one is. Then, you simply add up the coefficients of each compound on the products side of the equation. When the coefficient is not specified, you can assume it is 1 mole. So, in this equation, there is 1 mole of CaCl₂, 1 mole of CO₂, and 1 mole of H₂O = 3 moles.
The reactant side of the equation also has three moles:
1 mole of CaCO₃ and 2 moles of HCl.
