During the rock cycle, sedimentary rocks are returned to the Earth's interior and become metamorphic rocks through metamorphism.

Metamorphic rocks can then move even deeper into the Earth's interior and melt into magma.
What phenomenon is responsible for moving sedimentary and metamorphic rock into the Earth's interior?
A. plate tectonics
B. infiltration
C. condensation
D. the carbon cycle

A 27.0-g object moving to the right at 21.5 cm/s overtakes and collides elastically with a 11.0-g object moving in the same dire
7nadin3 [17]

Answer:

final speed of the first object: 17.73 cm/s

final speed of the second object: 24.23 cm/s

Explanation:

Data:

mass of the first object, m1 = 27.0 g

mass of the second object, m2 = 11.0 g

initial speed of the first object, v1i = 21.5 cm/s

initial speed of the second object, v2i = 15 cm/s

final speed of the first object, v1f = ? cm/s

final speed of the second object, v2f = ? cm/s

Elastic collisions formula:

v1f = (m1 - m2)/(m1 + m2) * v1i + 2*m2/(m1 + m2) * v2i

v1f = (27 - 11)/(27 + 11) * 21.5 + 2*11/(27 + 11) * 15

v1f = 17.73 cm/s

v2f = 2*m1/(m1 + m2) * v1i + (m2 - m1)/(m1 + m2)*v2i

v2f = 2*27/(27 + 11) * 21.5 + (11 - 27)/(27 + 11)*15

v2f = 24.23 cm/s

A spring on Earth has a 0.500 kg mass suspended from one end and the mass is displaced by 0.3 m. What will the displacement of t
Alisiya [41]

Answer:

The displacement of the same mass on the same spring on the Moon is 0.05 m.

Explanation:

Given;

mass suspended from one end of the spring, m = 0.500 kg

displacement on the spring on Earth, x = 0.3 m

Apply Newton's second law of motion;

F = ma = mg

where;

m is mass on the spring

g is acceleration due to gravity

Also, apply Hook's law;

F = Kx

where;

K is force constant

x is extension or diplacement of the spring

Combine the two equations from the two laws;

mg = kx

when the spring in on Earth;

0.5 x 9.8 = 0.3k

4.9 = 0.3k

k = 4.9 / 0.3

k = 16.333 N/m

when the spring is on moon;

mg = kx

mass is the same = 0.5 kg

acceleration due to gravity on moon = ¹/₆ that of Earth =  ¹/₆  x 9.8 m/s²

0.5 (¹/₆  x 9.8) = 16.333 x

0.8167 = 16.333 x

x = 0.8167 / 16.333

x = 0.05 m

Therefore, the displacement of the same mass on the same spring on the Moon is 0.05 m.

What is an example of non-renewable energy source?​
Dominik [7]

Answer: coal

Explanation:  Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs
