Answer:
Thrust = 200 N
Explanation:
The engine thrust can be found by using the following formula:
where,
m = mass flow rate of the fuel = 0.05 kg/s
v = velocity of ejected gases = 4000 m/s
Therefore, using the given values in the equation, we get:
<u>Thrust = 200 N</u>
The algebraic expression for the component of the normal force in the vertical direction is Force= product of mass and area.

What is Force?</h3>
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction. Or, there is a specific meaning to the word "force." At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.

Answer:
A) 
B) 
Explanation:
A) Using the Archimedes' force we can find the weight of water displaced:
Where:
: is the weight of the block in the air = 20.1 N
: is the weight of the block in the water = 15.3 N
Now, the mass of the water displaced is:
The volume of the block can be found using the mass of water displaced and the density of the water:
B) The density of the block can be found as follows:

Answer:When prfessionals take data collections its important becasue it can cause error. Lets say they are sloppy with thier work and end up getting something that is not near what should be happening. This can have a major affect on the truth of what they are doing and an effect on thier end result in general.
