Answer:
4 N to the right
Explanation:
For the object in this problem, we have 2 forces acting on it:
- A force of 2 N, to the right
- A force of 2 N, to the right
The two forces are in line: this means that the two vectors can be simply added by calculating their algebraic sum.
If we take right as positive direction, the two forces can be written as
F1 = +2 N
F2 = +2 N
So, the net force will be
And the positive sign means the direction is to the right.
Answer:
4.99 mg of vitamin C are in the beaker.
Explanation:
Given that,
Weight of vitamin = 0.0499 g
Molar mass = 176.124 g/mol
Weight of water = 100.0 ml
We need to calculate the mg of vitamin C in the beaker
We dissolve 0.0499 g vitamin C in water to from 100.0 ml solution.
100 ml solution contain 49.9 mg vitamin C
Now, we take 10 ml of this vitamin C solution in breaker
Since, 100 ml solution =49.9 mg vitamin C
Therefore,
Hence, 4.99 mg of vitamin C are in the beaker.
