The child's linear speed is
              
    <em> (pi / 5) x (the child's distance from the center of the ride, in feet)</em>

                                                                                        feet per second.

Find the magnitude of the torque that acts on the molecule when it is immersed in a uniform electric field of 6.19×105 N/C with
Ivan

Answer:

\tau=5.81\times 10^5p\ N-m

Explanation:

We have,

Electric field, E=6.19\times 10^5\ N/C

The electric dipole vector at an angle of 69.9 degrees from the direction of the field.

The torque acting on a molecule is given by :

\tau=p\times E\\\\\tau=pE\sin\theta

p is electric dipole moment

\tau=p\times 6.19\times 10^{5}\times \sin (69.9)\\\\\tau=5.81\times 10^5p\ N-m

So, the magnitude of the torque acting on the molecule is 5.81\times 10^5p\ N-m.

The chief by 3 3/4 kg of Apple's 7 1/4 kilograms of peers and 10 1/8 kilograms with orange about how many kilograms of fruit did
WARRIOR [948]
SOLUTION:

Total amount of fruit = Total amount of apples + Total amount of pears + Total amount of oranges

Total amount of fruit = 15 / 4 + 29 / 4 + 81 / 8

Total amount of fruit = 30 / 8 + 58 / 8 + 81 / 8

Total amount of fruit = 169 / 8

Total amount of fruit = 21.125 kg

ANSWER:

Therefore, the chief bought 21.125 kg of fruit all together.

At which point is the water table closest to the surface? Explain.
dangina [55]

The point is the water table closest to the surface in valleys.

In areas of topographic relief, the water table generally follows the surface but tends to approach it in valleys and intersect the surface with streams and lakes. Closest to the surface is the vented zone where the interstices between the soil are filled with both air and water. Below this layer is a saturation zone where the gaps are filled with water.

The water table is the subsurface boundary between the soil surface and the area where groundwater saturates the space between sediment and rock fissures. At this boundary, water pressure equals atmospheric pressure. The top surface of the groundwater is the groundwater table. Beneath this surface, all pore spaces and cracks in sediments and rocks are completely filled and saturated with water. Groundwater occurs in these saturated layers known as saturation zones or water vapor zones.
