Answer:
C
Explanation:
Which wavelength of the electromagnetic spectrum are shorter than visible light and carry more energy
A micro
B radio
C ultraviolet
F infrared
The correct answer is C
The visible light wavelength is of 7 × 10^-7 m while the ultraviolet is of other
4 × 10^-8 m
Therefore, ultravolet is shorter than visible light and carry more energy
Therefore, the correct answer is option C.
Answer:
A 10 N force pointing up
Explanation:
If the net acceleration of the object is horizontal pointing to the right, that means that all vertical forces must have canceled out, and the only ones "unbalanced" are the horizontal ones (10 N to the right minus 5 N to the left giving a net force of 5 N to the right).
Since they mentioned only one vertical force pointing down (10 N), there must be another one of same magnitude but pointing in opposite direction (up).
Then there must also be a 10 N force pointing up acting on the object.
Answer:
D. Solution
Explanation:
Sugar dissolved in water is an example of solution.
A solution is a homogenous mixture of solutes and solvents.
In a solution the solute particles ae distributed uniformly in the solvents. The solute is the substance and it is the sugar here that is dissolved to make a solution.
The solvent is the water in this instance that helps to dissolve the solute.
