The Law of Conservation of Matter states that the mass of the reactants equals the mass of the products.
Thus, your answer is A
Answer: a few ton
Explanation:
Average-sized star like sun eave behind white dwarfs and they are almost of the same size as the earth due to gravity .
A teaspoon of white dwarfs is about 15tons.
Answer:
Index of Refraction = 1.52
Explanation:
The index of refraction or the refractive index is given as:
Index of Refraction = Sin i/Sin r
where,
i = angle of incidence
r = angle of refraction
In this case of karo syrup, we have the following data:
i = angle of incidence = 30°
r = angle of refraction = 19.24°
Therefore, substituting these values in the equation, we get:
Index of Refraction = Sin 30°/Sin 19.24°
Index of Refraction = 0.5/0.3295
<u>Index of Refraction = 1.52</u>
Hence, the refractive index or the index of refraction of the Karo Syrup is found to be <u>1.52</u><u>.</u>
<span>The potential energy is mgh. The kinetic energy is (1/2)mv^2. Total mechanical energy means the sum of those. The velocity is 0 since its just hanging.
A 0.100-kilogram apple falls from a height of 1.50 meters to 1.00 meters. Ignoring frictional effects, what is the kinetic energy of the apple at this height? Its equal to the change in PE from 1.5 meters to 1.0 meters. PE = mgh.</span>
