Answer:
The distance traveled by the skier is 5.309 km
Solution:
As per the question:
Mass of the skier, m = 64 kg
Coefficient of friction between the ski and the snow, 
Mass of snow, M = 5.0 kg
Now,
To calculate the distance, 's' traveled by the skier, in order to melt 5.0 kg of snow:
We know that:

where
= coefficient of friction
N = Normal Reaction
N = mg
Thus
(1)
Also,
(2)
where
= Latent Heat of fusion
Thus from eqn (1) and (2):


s = 5.309 km
Answer:
Explanation:
Every chemical reaction can be represented by simple chemical equations that shows how compounds are combining to give some products.
Such reactions are usually made up of:
Reactants on the left hand side
Products on the right hand side
Reactants → Products
In this given problem;
Reactants are : Magnesium fluoride = MgF₂
Iodine in form of Iodide = I₂
Product : Magnesium iodide = MgI₂
MgF₂ + I₂ → MgI₂ + F₂
Answer:
B. The particles that make up material B have more mass than the
particles that make up material A.
Explanation:
Answer:
The importance of the sediments permeability is that if it is permeable, water will flow easily through the sediment and thereby produce a very good supply of water for the well.
Explanation:
When digging a well into saturated sediments, the possibility of the sediment with either little saturation or full saturation being able to provide steady water supply will be limited by how permeable it is. Now, the importance of the sediments permeability is that if it is permeable, water will flow easily through the sediment and thereby produce a very good supply of water for the well.
The answer to what experimental result required considering the particle nature of light is A. The ultraviolet catastrophe of blackbody radiation.
