8 0

Answer:

Solar cell generates DC

Windmill generates AC

Explanation:

Solar cell generates DC from the panel, to use this DC for electricity it has to be passed to an inverter which convert DC to AC.

Windmill generates AC from the wind blades. This type of energy can be used directly with household appliances using AC, or passed to a rectifier to convert it to DC.

Acceleration of gravity is proportional to  1/D² .
('D' is the distance from the Earth's center.)

We need  (D / R)² = 9.8
('R' is the Earth's radius.)

D/R = √9.8 = 3.13

Distance from Earth's <u>center</u> = 3.13 R
Distance above Earth's <u>surface</u> = 2.13 R = about 13,570 km =====================================================

Jenny is sitting on a sled on the side of a hill inclined at 15°. What force is required to keep the sled from sliding down the
WINSTONCH [101]

Answer:

504 N

Explanation:

The force that starts the sled to slide down is:

F = mg sin Ф = 90lb * 9.81m/s² * sin 15° = 198.4kg * 9.81m/s² * sin 15°

Consider the electric field lines drawn below for a configuration of two charges. Several locations are labeled on the diagram.
geniusboy [140]

Answer:

The magnitude or strength of an electric field in the space surrounding a source charge is related directly to the quantity of charge on the source charge and inversely to the distance from the source charge. The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge.

Explanation:

I really hope this helps you!
