Answer:
D a thermometer
Explanation: It measures and track Celcius and Feirinheit.
The center of gravity is a SIKKE bro you really thought I’d give the answer of something so simple
To solve this problem it is necessary to apply the concepts related to Newton's second law, the definition of density and sum of forces in bodies.
From Newton's second law we understand that
Gravity at this case)
Where,
m = mass
a= acceleration
Also we know that

Part A) The buoyant force acting on the balloon is given as

As mass is equal to the density and Volume and acceleration equal to Gravity constant



PART B) The forces acting on the balloon would be given by the upper thrust force given by the fluid and its weight, then




PART C) The additional mass that can the balloon support in equilibrium is given as




Answer: Changes in pressure have very little effect on the volume of a liquid. Liquids are slightly incompressible because any increase in pressure can only slightly minimize the distance between the closely packed molecules. Hope this helps.
Explanation:
The main purpose of the turbine in the turbojet engine is to "<span>compress the air". There is also the added factor of pushing the air, which increases mobility. </span>
