<span>3 meters a second.
Every 5 seconds, that runner should run 5*3=15 meters
(distance = average velocity times time).
That means that your slope must be 15meters / 5 seconds. </span>
Answer:
2, less than the change in momentum
Explanation:
hope this helps!! :)
Using momentum balance:
The 588 N mother is on the other side of the seesaw, 2.20m away from the pivot
F1 = 588 N
x1 = 2.20 m
Two of her children sat on the other side:
F2 = 256 N
x2 = 2.00 m
F3 = 412 N
x3 = unknown
F1x1 = F2x2 + F3x3
Solve for x3:
588 * 2.2 = 256 * 2 + 412 * x3
x3 = 1.90 meters away from pivot
Answer:
Thin, aluminium and buried underground.
Explanation:
When it comes to electrification of a state or province, some characteristics of the wire to use must be considered. This would help to minimize and avoid power loss and wire burns.
i. The wire to use should be thin, and a quite number can be twisted one against the other so as to increase the surface area for heat dissipation.
ii. Aluminium wire is more preferable for this project. It has a high melting point, and reduces energy loss.
iii. Burying the wire underground through an insulator is the best choice, though expensive but would preserve the wire from external influence.
An ocean's salinity is affected by water and air temperature, the volume of water that flows into it, its age and the chemical composition of surrounding geological formations.<span> Because the effect of these factors varies over the area of an ocean, different levels are found within the ocean</span>
