Answer:
A. the box accelerated to at 1.0 m/s² to the right because the net force is 17N to the right.
Explanation:
To solve this problem, we need to find the net force acting on the body;
Net force = Forward force - Backward force
Forward force = 35N
Backward force = 18N
Net force = 35N - 18N = 17N
So;
Net force = mass x acceleration
17 = 17 x acceleration
Acceleration = 1m/s²
Therefore, the body moves in the forward direction with an acceleration of 1m/s²
The equation that you’re looking at is Cu (copper) + HCl (hydrochloric acid) —> CuCl (copper chloride). This doesn’t work because copper chloride doesn’t contain hydrogen. The equation would only work if the reactants were chlorine and copper only.
Answer: The increasing wavelength of colors:
Red > Green > Blue
Explanation:
Wavelength: This is the property of wave which includes the distance between two consecutive crests or trough. This is denoted by the Greek letter Lambda and it is found by dividing the velocity of the wave with its frequency.
Wavelength of colours are
Violet: 400 - 420 nm
Indigo: 420 - 440 nm
Blue: 440 - 490 nm
Green: 490 - 570 nm
Yellow: 570 - 585 nm
Orange: 585 - 620 nm
Red: 620 - 780 nm
