Answer:
1) Buoyant force, 2) sinks, 3) equilibrium, 4) fleet , 5) LIFT force
Explanation:
A body in a fluid is subjected to two forces, its weight and the thrust
sun F = B - W
the em
bid is always vertical and contrary to weight, let's analyze and complete the different situations presented
1) Buoyant force
2) sinks B <W
3) equilibrium B = W
4) fleet B> W
5) by the sum of two forces:
* Thrust, but the density of air is much less than the density of water, therefore the thrust in the air is less.
* The other force in airplanes the lift force given by the difference in the path of the air when the plane moves, which translates into a pressure difference between the upper part of the wing and the lower part, it is force is called LIFT force

Answer:
for question no.4,
time =6 secs
acceleration due to gravity (g)= 9.8 m/s^2
velocity=gt
=6×9.8
=58.8m ans...
for question no .5,
time taken = 4seconds
aacceleration due to gravity (g)=9.8 m/s^2
distance=12gt
=12×9.8×4
=470.4meter answer...
Answer:
Acceleration of the object is .
Explanation:
It is given that, the position of the object is given by :
Velocity of the object,
Acceleration of the object is given by :
Using the property of differentiation, we get :
So, the magnitude of the acceleration of the object at time t = 2.00 s is . Hence, this is the required solution.
Answer:
640 J
Explanation:
At constant pressure, work = pressure * change in volume.
First, let's convert to SI units.
200 kPa = 200,000 Pa
3.4 L - 0.2 L = 3.2 L = 0.0032 m³
Therefore:
W = (200,000 Pa) (0.0032 m³)
W = 640 J
