Answer:
lift force = 0.213 N
Drag force =
Explanation:
Given: velocity v = 10 m/s
w = 100 rev/sec
diameter d = 3cm
density D = 1.2kg/m3
lift force =
Substituting the values into the equation, we obtain
lift force = 0.213 N
Drag force = C*D*A*v/2
where C = 0.5
substituting the values into the equation again, we have
Drag force =
Answer:
Prevost's theory of exchanges stated that each body radiates to, and receives radiation from, other bodies. ... Prevost went on to comment that "The heat of several portions of space at the same temperature, and next to one another, is at the same time in the two species of equilibrium."

The answer is option D.
Area of sheet, A1 = length × breadth
= (8.5 inch * 2.54 cm) ×11 inch * 2.54 cm)
= 603.22
Now, Mass of sheet, M1 = 4.50 gms
Thus, Area of sheet A2, = 1
And, Mass of sheet, M2 = ?
Thus, Mass of M2 =
= 0.0073
Solar system is nested nearly 2/3 of the way from the center of the galaxy to the outskirt of the galactic disc.
