Answer:

A) the same in all gases.

Explanation:

The Thomson's experiment showed that the charge-to-mass ratio of electron was Same in all gases.

J.J. Thomson in his Cathode ray experiment showed that the atoms are made of aggregate charged particles. Until his demonstration it was believed that atoms were smallest unit. In his calculation he also showed that charged to mass ratio is same in all the elements.

$\frac{e}{m} = constant = 1.7588196$ × $10^{1} 1\frac{C}{kg}$

Four bricks of length l, identical and uniform, are stacked on top of one another (the figure) in such a way that part of each e

xeze [42]

The maximum values of a₁, a₂, a₃, a₄ and h to make the stack in equilibrium are; a₁_max = L/2; a₂_max = L/4; a₃_max = - L/6; a₄_max = -L/8; h = 25L/24

<h3>What is the maximum width?</h3>

The system is in equilibrium and length of each brick = L

a) For brick 1;

Due to the fact that the center of gravity lies to the right of L/2,

Then we can say that the maximum value of a₁ = L/2

b) For brick 2;

Since the center of gravity lies to the right of L/2, then we can say that;

The maximum value of a₂ = ¹/₂a₁_max

Thus, the maximum value of a₂ = L/4

c) For brick 3;

Taking the moment of force, the maximum value of a₃ is;

a₃_max = [(-¹/₂mL) + 2m(0)]/(2m +m)

a₃_max = - L/6

d) For the brick 4;

Taking the moment of force, the maximum value of a₄ is;

a₄ = [3(0) m + m(-L/2)]/(3m + m)

a₄_max = -L/8

e) The value of h = |a1| + |a2| +|a3| + |a4|

h = L/2 + L/4 + L/6 + L/8

h = ((12 + 6 + 4 + 3)/24)L

h = 25L/24

12 grams (g) of a chemical are added to a metal. The amount A, in grams, of the chemical

andriy [413]

Answer: A=12

Explanation:

4.5

The amount of chemical remaining after twelve seconds in the first reaction is:

A = 12 - 0.5(12)

= 12 - (6)

= 6

In the dissolved reaction, the amount of chemical loses half of itself every four seconds. This is the same thing as dividing by 2 every four seconds.

This is an exponential decay, so the amount of chemical divides by 4 every eight seconds, and by 8 seconds every twelve seconds. The amount remaining after twelve seconds in the second reaction is:

A' = 12/8

= 3/2

= 1.5

The difference between the amounts of chemical remaining is:

6 - 1.5 = 4.5

Therefore, A is 4.5 g greater than A' after twelve seconds.

Which are shown on a balance sheet? Select three choices. assets liabilities age time period date of birth

Bond [772]

Assets, liabilities, time period should be shown on a balance sheet.

Balance Sheet are often regarded as financial statement that simply tells a brief summary of a company's assets, liabilities and shareholders' equity at a particular point in time.

Assets are said to be company's or individual's resource that is of economic importance corporation or that belongs or controled by country with the view that it will give future benefit.

From the above, we can therefore say that the answer Assets, liabilities, time period should be shown on a balance sheet is correct
