(31-15 = 16).
Explanation:
the element phosphorus (P) has an atomic number of 15 and a mass number of 31. Therefore, an atom of phosphorus has 15 protons, 15 electrons, and 16 neutrons
Answer:
w = 73 N
Explanation:
Since the box is held by the ropes it means that the resulting tension is equal to the weight of the box
T_res = w
Now, the resulting tension is a combination of the tension of each rope.
Since we want to find the vertical component we must multiply by the cosine of 30 degrees the value of T
T_res = T*cos(30) + T*cos(30)
T_res = 2*(42 N)*(0.866)
T_res = 72.746 N
T_res = w = 72.746 N
Answer:
The slope is 0.5
Explanation:
It increases so it is positive and it increases by half a block each time so 0.5.

Answer:
The question is incomplete because the options are not given. We'll solve this question with the options.
There are two properties of negative charges which we have to consider to find the figure of its electrical field.
Firstly, for a negative charge, the electrical field lines are always directed radially outwards and they don't intersect.
Secondly, we know that similar charges repel each other, so there will be no electrical field present directly between these two negative charges. Electrical field line will be present between two charges only when there is a force of attraction.
Taking both of these facts into consideration, the electrical field line between two negatives is represented by the figure below.
