Explanation:
Answer:
An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.
Explanation:
Answer:
A Glucose C6H12O6 is a covalent compound while NaCl sodium chloride is a ionic compound.
B Stronger molecular forces are present in NaCl because ionic bond is stronger than covalent bond.
C melting point allow us to predict the strength of intermolecular forces
High melting point stronger molecular forces and vice versa.
Explanation:
15c - 1.2m
1c - 1.2/15 = 0.08m
65c - 5.2m
Answer:
A heatwave occurs when a system of high atmospheric pressure moves into an area and lasts two or more days.
Explanation:
In such a high-pressure system, air from upper levels of our atmosphere is pulled toward the ground, where it becomes compressed and increases in temperature.
