40 mi/h means miles per hour
Answer:
D-The asthenosphere and outer core would solidify.
Explanation:
The athenosphere is a region of the earth mantle below the lithosphere.
If the Sun didn’t retain the heat formed during its formation then it will have an adverse effect on other parts such as the core and mantle.The inner core wouldn’t liquefy but solidify. The asthenosphere and outer core would also solidify.
The Seismic waves wont be able to move the crust and the Earth’s magnetic field wouldn’t disappear but would be more pronounced.
Answer: D) Do rougher surfaces tend to create more friction than smooth surfaces?
Explanation:
Friction acts when either there is tendency or actually relative motion between two surfaces in contact. It depends upon the area of contact surface and roughness of the surfaces. More the area and roughness, more friction would be there. More friction would mean more force would be required to cause the relative motion between the two surfaces.
Here, sally and sue are changing the surface over ramp on which car moves. The surface area is same. The angle is same and the speed of the car is also same. So, the best research question to guide the girls' experiment would be D) Do rougher surfaces tend to create more friction than smooth surfaces?
Answer:
The temperature and the pressure both increase as we go deeper within the Earth, toward its core.
Explanation:
Current(I) = Voltage(V) / Resistance(R)
Since (V) is constant, as (R) decreases, (I) increases.
