I believe your answer is correct, because 8.7*10^-7 is equal to 0.00000085347.
Hope you do well!
Answer:
195N
Explanation:
F1*b1=F2*b2
F2=F1*b1/b2; F2=45*13/3=195N
The real world application of the atwood’s machine is to be
able to demonstrate specific principles such as the acceleration and dynamics
in a way to understand and know how it is being demonstrated in the real world
and in different situations.
Answer:
C. less than 950 N.
Explanation:
Given that
Force in north direction F₁ = 500 N
Force in the northwest F₂ = 450 N
Lets take resultant force R
The angle between force = θ
θ = 45°
The resultant force R
R= 877.89 N
Therefore resultant force is less than 950 N.
C. less than 950 N
Note- When these two force will act in the same direction then the resultant force will be 950 N.
Answer: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.
