Answer:
Decrease
Explanation:
Acceleration is inversely proportional to the mass of an object.
Acceleration decrease as the mass of the object increase
If u use the formula F=ma to calculate, you will get
a=0.5m/s2 for the first situation (m=10kg) and a=0.25m/s2 for the second situation (m=20kg)
Answer:D
Explanation:Mantle convection currents cause plate movement
Answer:
Yes
Explanation:
No matter what age, trees still give out oxygen. It may not be the same amount as an older tree, but it still has the same effect.
Answer:
The correct answer is C) 1 L of 1.0 M NaCl
Explanation:
NaCl is a ionic compound so it dissociates in water into Na⁺ and Cl⁻ ions. Glucose is a covalent solute so it does not dissociates into ions. So, when we dissolve NaCl we have twice the amount of particles in solution in comparison with glucose. According to this:
A) and B) are solutions with the same concentration (0.5 M) but NaCl solution will have more solute particles than glucose.
C) and D) are solutions with more solute amount because they are more concentrated (1 M), but NaCl solution will have more solute particles than glucose solution ( 1 mol of Na⁺ ions + 1 mol of Cl⁻ ions).
The solution with the greatest solute particle number is C).
The destructive force of the wave is not felt while they are out at the sea but it is felt when they approach the shore.
<u>Explanation:</u>
When the waves are out in the ocean they are in deeper waters. Once they move towards the shore they approach shallow waters. This movement causes shoaling of the waves by which its amplitude increases.
When the wave reaches the shore its leading edge gets slowed down by coming in contact with the beach floor but its trailing edge which is still in deep water still moves rapidly. The wave thus gets compressed and its wavelength decreases. The amplitude of the wave then increases rapidly making the wave destructive.
