Static friction because the rocks arent moving are they?
In the holes there is brass "fingers" that grab the plug prongs when you plug it in. So it's made out of brass or copper.
That would be false.
Straight angle= 180 degrees
Obtuse angle= Above 90, and lower than 180
Acute angle= Below 90
Hope this helps! (:
Answer:
A) R = 1019.11 Ω
B) V = 101.91 V
Explanation:
a) The resistance is given by the formula;
R = ρL/A
Where;
ρ is bulk density = 5.0 Ωm
L is length of cylinder = 1.6m
A is area = (π/4)D² = (π/4) x 0.1² = 0.007854 m²
Plugging in the relevant values, we obtain ;
R = (5 Ωm x 1.6m)/(0.007854 m²)
R = 1019.11 Ω
b) potential difference is given by;
V = RI
Thus, plugging in relevant values, we obtain;
V = 1019.11 Ω ∙ 0.1A
V = 101.91 V
Answer:
You can tell the difference between physical and chemical change by looking at the change that takes place like whether it is a permanent or temporary change.
Explanation:
- physical change is temporary change and chemical change is permanent change
- the original shape of the object can be restored in physical change whereas the original composition of the object will be lost in chemical change
- in physical change the change is reversible whereas he chemical change is irreversible and the object takes new shape and position in this change.
