6 0

Answer:

Option D. ⁸⁵₃₆Kr

Explanation:

⁸⁵₃₅Br —> ⁰₋₁e + ?

Let ⁿₘZ represent the unknown.

Thus, the equation becomes:

⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ

Next, we shall determine n, m and Z as follow:

85 = 0 + n

85 = n

Thus,

n = 85

35 = –1 + m

Collect like terms

35 + 1 = m

36 = m

Thus,

m = 36

ⁿₘZ => ⁸⁵₃₆Z = > ⁸⁵₃₆Kr

Thus, the equation:

⁸⁵₃₅Br —> ⁰₋₁e + ⁿₘZ

Becomes:

⁸⁵₃₅Br —> ⁰₋₁e + ⁸⁵₃₆Kr

Temperature is related to a physical change of a substance because it determines the state of the object via cooling, heating or freezing. To make the concept clear, hear are some examples:-
1. Chocolate melts and turns into liquid form. This is a physical change
2. Water freezes via cooling and forms ice which is in a solid state. This is another physical change

Hope this helped and have a nice day : )

Two horses on opposite sides of a narrow stream are pulling a barge up the stream. Each hors pulls with a force of 720N. The rop
Sonja [21]
For the answer to the question above, each horse's force forms a right angle triangle with the barge and subtends an angle of 60/2 = 30°. The resultant in the direction of the barge's motion is:
Fx = Fcos(∅)
We can multiply this by 2 to find the resultant of both horses.
Fx = 2Fcos(∅)
Fx = 2 x 720cos(30)
Fx = 1247 N
