The electron was discovered by researchers working with cathode ray tubes.
A solution is a homogeneous mixture of two or mores substances at molecular level mainly solute and solvents. A solution may be saturated, supersaturated or unsaturated. A saturated solution is when the solution has dissolved the maximum solute at a given temperature, unsaturated solution is a solution which can still dissolve more solute at a given temperature to achieve saturation. In this case, if a solution is forced to dissolve more solute than it normally can dissolve, the solution is supersaturated.
Answer:
25 seconds!
Explanation:
I just had to find what number to multiply 4 to get 100 and it was 25
4x25=100
Or you could do the easier way by dividing 100 by 4 which has the same answer: 25
100÷4=25
there are three picture with example and sentence
Answer:
<em>a) 37.5N</em>
<em>b) 9.375Joules</em>
Explanation:
a) According to Hooke's law
F = ke
k is the spring constant
e is the extension;
F = 150 * 0.25
F = 37.5N
b) Work done on the spring = 1/2ke^2
Work done on the spring = 1/2 * 150 * 0.25^2
Work done on the spring = 75 * 0.0625
Work done on the spring = 9.375Joules
