Calcula la distancia que debe haber entre un pisa papel y una biblia tipo masas son de 250g y 650g con una fuerza cuya magnitud
1 answer:
Answer:
r = 0.765 m
Explanation:
For this exercise let's use the law of universal gravitation
F =
r =
let's reduce the magnitudes to the SI system
m₁ = 250 g (1 kg / 1000g) = 0.250 kg
m₂ = 650 g (1 kg / 1000g) = 0.650
F = 1.85 10-6 dynes (1 N / 10⁵ dynes) = 1.85 10-11 N
let's calculate
r =
r = √0.58587
r = 0.765 m

The gravitation force is 1/6 that of earth, and the ice in the same soft drink would float with 9/10 submerged option (B) is correct.
<h3>What is gravitational force?</h3>All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.
As we know, the gravitational force is given by:
Where G is the gravitational constant.
m1 and m2 are masses.
r is the distance between the masses.
Weight of ice cube = weight of soft drink displaced
mg = ρVg
m = ρV
g does not affect astronauts on earth in a lunar module.
Thus, the gravitation force is 1/6 that of earth, and the ice in the same soft drink would float with 9/10 submerged option (B) is correct.
An astronaut on Earth notes that in her soft drink an ice cube floats with 9/10 of its volume submerged. If she were instead in a lunar module parked on the Moon where the gravitation force is 1/6 that of Earth, the ice in the same soft drink would float:A) with more than 9/10 submerged. B) with 9/10 submerged.C) with 6/10 submerged.D) totally submerged.

Answer:
2.35 kgm^2
Explanation:
we take length 68.7 cm as x-axis and 47.5 cm as y-axis then the axis about which we have to find out moment of inertia will be z-axis.
moment of inertia about x-axis
kg-m2
by perpendicular axis theorem
