Answer:
9.45 kWh
Explanation:
Energy = Power × time
E = 900 W × (1.5 h/day × 7 day)
E = 9450 Wh
E = 9.45 kWh
The positively charged atmosphere attracts negatively charged spider silk, might electrostatic force play in spider dispersal, according to a recent study.
Answer: Option C
<u>Explanation:</u>
The positive charge present in upper of the atmosphere and the negative charge on planet’s surface. During cloudless skies days, the air possesses a voltage of nearly around 100 volts for each and every meter from above the ground.
Ballooning spiders process within this planetary electric field. When their silk relieve their bodies then it picks up a negative charge. This oppose the similar negative charges on the surfaces on which the spiders settles and create sufficient force to lift them into the air. And spiders can hike those forces by climbing onto blades of grass,twigs, or leaves.

<h2><em>A. Rotation of Earth</em></h2>
<em>The moon rises in the east and sets in the west, each and every day. It has to. The rising and setting of all celestial objects is due to Earth's continuous daily spin beneath the sky</em><em>.</em>

Answer:
C. Angle of Attack.
Explanation:
The pilot must adjust the angle of attack parameter. The angle of attack of this plane to get to the desired lift coefficient.
And thus, we have
Lift = Weight
Answer: ![6.408(10)^{-19} C](https://tex.z-dn.net/?f=6.408%2810%29%5E%7B-19%7D%20C)
Explanation:
This problem can be solved by the following equation:
![\Delta K=q V](https://tex.z-dn.net/?f=%5CDelta%20K%3Dq%20V)
Where:
is the change in kinetic energy
is the electric potential difference
is the electric charge
Finding
:
![q=\frac{\Delta K}{V}](https://tex.z-dn.net/?f=q%3D%5Cfrac%7B%5CDelta%20K%7D%7BV%7D)
![q=\frac{7.37(10)^{-17} J}{115 V}](https://tex.z-dn.net/?f=q%3D%5Cfrac%7B7.37%2810%29%5E%7B-17%7D%20J%7D%7B115%20V%7D)
Finally:
![q=6.408(10)^{-19} C](https://tex.z-dn.net/?f=q%3D6.408%2810%29%5E%7B-19%7D%20C)
