Answer:
30 N
Explanation:
there are two forces act on the bar:
- weight of 1.5 kg mass, w = mg = 15 N
- weight of the bar, wb
for balance,
w * Lw = wb * Lwb
Lw = length of bar from the mass to the pivot
Lwb = lenght of bar from the center of the bar to the pivot
15 * 20 = wb * (50-20)
300 = wb * 30
wb = 300/30 = 30 N
When a person consumes too much soda e.g. having more than two servings a day are consumed, he or she is like to develop kidney stones and other renal problems such as kidney failure because of its high phosphoric acid content.
Answer:
Explanation:
<u>Average Speed
</u>
If an object travels a distance d in a time t regardless of the direction, the average speed is the quotient of the distance over the time:
It's known a person runs d=15 kilometers in t=2 hours, thus his/her average speed is:
Calculating:
<span>The isotope of an atom containing 40 protons and 51 neutrons suddenly has 2 neutrons added to it
That is X-93 so it will be
</span><span>Zirconium-93
</span>hope it helps
<span>If your speed changes from 10 km/h to 6 km/h, you have a negative acceleration. The correct option among all the options that are given in the question is the first option or option "a". The other choices are totally incorrect. I hope that this is the answer that has actually come to your help.</span>
