thrust force getting from the burning of mass should balance the weight of the rocket
here thrust force is given as
now by force balance we can say
now plug in all values in this
so rate of mass burning per second will be 5600 kg per second in order to lift up the rocket

Answer: I put the importance of the lab in the topic is to find how dense an object is and if it can sink or float and it's important to answer the question so you can also find mass and volume.

Answer:
Both hit at the same time
Explanation:
If air resistant is ignored, then gravitational acceleration g is the only thing that affect the bullets vertical motion, no matter what their horizontal motion is. Since both bullets are starting from rest, vertically speaking their speeds are 0 initially, they are both subjected to the same acceleration g, then they travel at the same rate and would reach the ground at the same time.
Answer:
option (A)
Explanation:
According to the Archimede's principle, when a body s immersed partly or wholly in a liquid, it experiences an upward force which is called buoyant force. The buoyant force is equal to the loss in the weight of body.
The weight of liquid displaces by the body is equal to the loss in weight of body.
Thus, option (a) is true.
