It's el mapa so the answer is incorrect. Even though mapa has an 'a' at the end, you will still use el.
Answer:
c.
Explanation:
If the object starts to slide it must be on a slope.
There are 2 forces acting on the object - gravity and the friction between the object and the surface.
If sliding starts then the forces must be unbalanced.
The force of gravity is greater than the friction.
Answer:
C2= 0.16M
Explanation:
C1= 2M, V1= 20ml, C2= ?, V2= 250ml
Applying dilution formula
C1V1= C2V2
2×20 =C2×250
C2= 0.16M
Answer:
The volume will decrease.
Explanation:
According to Charles' Law, the volume of a gas is directly proportional to its temperature.
V = kT
Thus, if T decreases, V decreases.
