As the sphere moves in the liquid, it experiences a viscous force upwards that tries to resist its downward motion caused by gravity(it's own weight). This viscous force gradually increases with depth, as the speed rises(because the weight causes a positive acceleration in it's direction). At a point, the viscous force upwards becomes exactly equal to the weight downwards. Then the sphere reaches equilibrium. It doesn't have any external force acting on it, so it can't have any acceleration. So, it's velocity becomes constant, and this velocity is known as the terminal velocity.
Answer:
Explanation:
Some data in the problem are missing.
Missing values:
Radius of the cylinder: 13 cm
Height of the cylinder: 4 cm
The volume of a cylinder is given by
where
r is the radius of the base of the cylinder
h is the height of the cylinder
In this problem, we have:
r = 13 cm (radius)
h = 4 cm (height)
Therefore, the volume of the cylinder is:
This is so sweet I wish the same back to you :))
I believe that says that the car is going 125 meter per 5 seconds
Answer:
<u>35.57 x 10²¹ N</u>
Explanation:
m(s) = 2 x 10³⁰ kg
m(e) = 6 x 10²⁴ kg
d = 1.5 x 10¹¹
G = 6.67 x 10⁻¹¹
F = Gm1m2/d²
= 6.67 x 10⁻¹¹ x 2 x 10³⁰ x 6 x 10²⁴ / 2.25 x 10²²
= 80.04 x 10⁴³ / 2.25 x 10²²
= <u>35.57 x 10²¹ N</u>
