Answer:
The action of erosion alone can change the earth's surface. Erosion can wash away nutrients on the earth's surface, change the appearance of the soil of a particular area over time, can bore holes, that form caves, change landscapes for example when the earth is hit with gully erosion by continuous water runoff over time. Erosion can move soil to a new area.
Explanation:
Weathering involves breaking down rock into smaller pieces without any form of formal movement of those broken rock pieces. These processes that can lead to weathering are caused by mechanical, chemical, and organic processes which can happen over time. Erosion can now move broken rock pieces or soil to another place by water or wind. Weathering and erosion constantly change the Earth's surface.
It belongs to hydrides, it’s a nitrogen hydride
It is a base because of pH and because it’s a soluble vase it is an alkali
Answer:
F= 15.6 N, a= 33.2 m/s^2
Explanation:
mass= m = 0.47 kg
spring constant= k = 130N/m
spring compression = x = 0.12 m
a).
force on the mass= F = k*x
F = 130 * 0.12 N
F= 15.6 N
b).
Acceleration of mass= a=?
F= ma
a=F / m
a= 15.6/ 0.47 m/s^2
a= 33.2 m/s^2
Answer
19 m/s
Explanation
<u>Finding the velocity of the initial object</u>
Momentum=mass × velocity
P=m×v
4000=115 × v
v=4000/115 =34.78⇒35m/s
<u>Total momentum after the collision</u>
Because the momentum is conserved, the total momentum afterwards =4000kg-m/s
<u>Total mass after collision</u>
Total mass = mass of initial object + mass of second object
Total mass= 115+100= 215kg
<u>Finding new velocity after collision</u>
v=p/m
=4000/215
=18.60
=19m/s
Answer:
I thinck it would be 48.0
