Answer:
Density is defined as mass per unit volume. its SI unit is: kg/m³
Explanation:
Explanation:
We know that the relation between volume and density is as follows.
Volume = 
So, V = 
= 
Now, we will calculate the area as follows.
Area = 
= 
= 
Formula to calculate the resistance is as follows.
R = 
= 
= 
Thus, we can conclude that the resistance of given wire is
.
I pretty sure that 3 is b and 4 is A and 5 I need a full picture
Answer:
by using formula F=ma which is m stand for mass a stand for acceleration. so 500kg × 2 ms^-2
