The land is warm during the day. For example, if you near a sea early in the morning, you could see how cold, cool the place is.
Answer:
4.375 milligram
Explanation:
Applying,
A = A'(2ᵃ/ⁿ)............. Equation 1
Where A = original amount of actinium-228, A' = amount of actinium-228 left after decay, a = Total time, n = half life
make A' the subject of the equation
A' = A/(2ᵃ/ⁿ)........... Equation 2
From the question,
Given: A = 70 milligram, a = 24.52 hours, n = 6.13 hours
Substitute these values into equation 2
A' = 70/(2²⁴°⁵²/⁶°¹³)
A' = 70/(2⁴)
A' = 70/16
A' = 4.375 milligram
No, when ascending, you would weigh more, and when you descend, you weigh less.
This is due to the difference in the effect of gravity.
Answer:
Explanation:
endergonic
A chemical reaction that has a positive ΔG is correctly described as A) endergonic.
Answer:
It has no fixed shape and therefore takes the shape of the part of the container in which it is placed
