Answer: High voltage transmission minimizes energy losses during electricity transmission.
Explanation:
When electricity is to be transmitted over a long distance, high voltage transmission is preferred to minimize energy losses due to heat.
The higher the transmission voltage, the lower the current and the lesser the resitance in the wire and the lesser the energy lost due to heat during transmission.
High voltage transmission in kilowatts enables light weight cables to be used for long distance electricity transmission.
This explains why, even though only 110 V may be required at home by some appliances, but electricity is transmitted in kilovolts and often require a stepdown transformer
Answer:
492.183 nm
Explanation:
x = Distance from the central maximum to the first minimum = 1.35 mm
l = Distance of screen = 2.13 m
d = Distance of gap = 0.705 mm
m = Order = 1
We have the relation
The wavelength of the light is 492.185 nm
Answer: Shield volcano is a broad, gently sloping, explosive volcano which is comprised of basaltic magma.
Shield volcano is normally not explosive but if somehow water comes in contact with this basaltic magma, then it turns into a more violent, explosive volcanoes, producing pyroclastic materials such as lapilli, lava bombs and block.

Answer:
Explanation:
<u>Centripetal Acceleration</u>
It's the acceleration that an object has when traveling on a circular path to take into consideration the constant change of velocity it must have in order to keep going in the circular path.
Being v the tangent speed, and r the radius of curvature of the circle, then the centripetal acceleration is given by
We can compute the value of v by using the distance and the time taken to travel:
Now we calculate the centripetal acceleration
