Thrust is a reaction force described quantitatively by Newton's third law. When a system expels or accelerates mass in one direction, the accelerated mass will cause a force of equal magnitude but opposite direction on that system. Mathematically can be written as,
Here,
v = speed of the exhaust gases measured relative to the rocket.
= Rate of change of mass with respect to time
Our values are given as,
Replacing we have that
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.
Answer:
a) At x=14 the slope will be given by:
.
b) Then, the angle between the line and the pole will be:
where is the angle between the tangent to the catenary and the x-axis.
Explanation:
The catenary has the following general form:
a) The slope at any point will be given by the derivative of y.
At x=14:
.
b) The angle between the tangent to the catenary and the x-axis at a given point will be given by:
⇒
Then, the angle between the line and the pole will be:
.
