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

When you have a chemical reaction, it means something goes wrong with your chemicals.
Answer:
10.9%.
Explanation:
The first thing to do in order to solve this question is to Determine the value for the volume of the the cube. This can be done by taking the cube root of the length of the cube;
The volume of the cube = (length of the cube)^3 = length × length × length = 1.72 × 1.72 × 1.72 =( 1.72)^3 = 5.09cm^3.
The next thing you do is to Determine the exponential density, the can be done by using the formula below;
The exponential density = mass/ volume = 55. 786/ 5.09 = 10.96 g/cm^3.
Therefore, the percent error = (true density of the cube - exponential density of the cube)÷ true density of the cube × 100.
Hence, the percent error = 12.30 - 10.96/12.30 × 100 = 10.9%.
