To solve this problem we must simply resort to Newton's second law as well as the relationship between pressure and force as a physical unit applied in a given area.
In mathematical terms the Weight can be expressed as
Where,
m = mass
g = Gravitational Acceleration
We have the mass and the gravitational acceleration therefore the Weight is
Replacing we have
In this way the pressure exerted according to the active Area is,
Therefore the pressure difference between the lower and upper surface of the wings is 9.14kPa
Answer:
B. Projectile motion is the correct one
Explanation:
This should be right. if any doubt post a comment.
Answer:
220 V
Explanation:
As the resistors are connected in series,
= 20 + 30 + 60
= 110 ohms
V = IR
= 2 * 110
= 220 V
Hope it helps
False, the object will weigh less because gravity is weaker on the moon.
