Answer:
The linear momentum is given by the following equation:
(1)
Where is the mass and the velocity.
On the other hand, the kinetic energy is given by:
(2)
Which is the same as:
Now, if we double the kinetic energy, equation (2) changes to:
(3)
So, if we want to obtain the kinetic energy as shown in (3), the only option that works is increasing momentum by a factor of or :
Applying this in (2):
>>>As we can see, this equation is the same as equation (3)
Therefore, the correct answer is B
Even though the mass of the earth stays the same, the force gravity has on us will double because there is less space in the atmosphere for the gravity to pull anything in towards its center. Let me know if I'm correct!
Fk= mgcostheta * coefficient of friction
Fk= (.05kg)(9.80)(cos30)(.20)=.085 N
change in thermal energy= Fk* distance covered up slope (d)
change in thermal energy = .085 * d
the final height so y=dsin30
Kf + Uf + change in thermal energy = Ki + Ui
(.05kg)(9.80)(dsin30) + (.085d) = (.5)(25 N/m)(.1m)^2
d= .379 m = 37.9 cm

Explanation:
D. Increase In Density
This is because more buoyancy an object has, the more it increases in density.
