Answer:
The most precise measurement is 1/36 yd.
Step-by-step explanation:
In order to compare measurements, you would need to first convert them all to the same form of measurement in order to place them from least to greatest. Since there are 12 inches per foot and three feet per yard, that would mean there are 36 inches per yard. Since the first two measurements 3/32 and 3/12 are both in inches, then we just need to convert 1/12 ft and 1/36 yd to inches. Since there are 12 inches per foot, we can multiply 1/12 x 1/12 to get 1/144 inches. Likewise, since there are 36 inches per yard, we can multiply 1/36 x 1/36 to get 1/1296 inches. Looking at our fractions, we see that 1/1296 inches would be the most precise measurement because it is the smallest fraction.
Explanation: 1 / 2 = 9 / 18 Halfway that and 0 would be 4.5 / 18 Since 3 / 18 is below that, we would round to 0
Correct question:
Which reaction describes a beta emission? 2659Fe→ 2759Co + −10e, 88226Ra→ 86222Rn + 24He, 94239Pu + 24He→ 96242Cm + 01n, 54118Xe→ 53118I + +10e
Answer:
2659Fe→ 2759Co + 1e
Step-by-step explanation:
General equation for beta decay is given as;
where;
A is the atomic mass of the element
z is atomic number of the element
X is the parent atom
Y is the daughter element
β is beta emission
In beta emission, there is loss of one electron and zero proton, the will cause the daughter element to gain on electron in order to balance the reaction.
Based on beta decay equation above, we select the reaction that describes beta emission.
2659Fe→ 2759Co + 1e
Here;
A = 59
z = 26
z + 1 = 27
1.You can see through the comparison to a mountain, that the grandpa is y’all and always the ‘looming’ (hovering) over the speaker you can see that the speaker does not speak much around his grandpa, as he is “silent as a stone”
2.These details show that the speaker is impressed by his grandpa and looks up to him the way a stone would look up to a mountain-it shows that he hopes one day he will grow to be like his grandpa
3.the theme of this poem is shown through the way the speaker looks at his grandpa and the shed. The shed needs more than paint because it’s so old, which relates to his grandpa and the theme of growing older
