Answer: The energy transfer occurs by convection (particle movement) and by radiation of heat and light. The potential energy from the batteries in the torch is transferred to the filament of the bulb. The energy is transferred to the surroundings as thermal energy and light

Determine the average distance between the Earth and the Sun. Then calculate the average speed of the Earth in its orbit in kilo

FrozenT [24]

Answer:

The average speed of the Earth in its orbit is 4.74 km/s.

Explanation:

Distance between the Earth and the Sun ,r= 149.60 million km = $149.60\times 10^6 km$

Considering the movement of Earth around the Sun follows circular path.

The circumference of circular path will be give by :

$D=2\pi r=2\times 3.14\times 149.60\times 10^6 km$

Time taken by Earth to complete revolution around earth ,T= 1 year

1 year = 365 days

1 year = 31,536,000 seconds

T = 31,536,000 seconds

Speed of the Earth around the Sun :S

$S=\frac{D}{T}=\frac{149.60\times 10^6 km}{31,536,000 s}$

$S=4.74 km/s$

The average speed of the Earth in its orbit is 4.74 km/s.

An object moves with constant acceleration 3.45 m/s2 and over a time interval reaches a final velocity of 14.0 m/s.

Sav [38]

Assuming the object was originally at rest, it must have been traveling for
14.0/3.45 = 4.06 seconds
