B.
Explanation:
because the ozone layer absorbs the greater part of the solar ultraviolet radiation.
Answer:
Explanation:
From the given information;
Let Q(t) = mass of dye in the tank as a function of time
The mass in the tank = 200 L × (1g/L) = 200 g
Using the law of mass conservation;
Q(0) = 200
By finding the solution to the ODE using the method of separation of variables;
Using the initial condition;
200 = Q(0) = C
1% of 200g = 2g of dye solution
∴
t = 460.5 hours
Sugar dissolving in warm water is an example of physical change.
physical change is doesn't alter the composition or the identity of the substance .
That's mean when you dissolves sugar in water, after a while the object will be the same which mean that the component doesn't change
