Which is a characteristic of a step–down transformer?
1 answer:
<u>Answer</u>:
Step Down Transformer: The Transformer that expands the voltage from Primary (essential) to Secondary (auxiliary) (more optional twisting turns than essential winding turns) loops called Step Down Transformer.
<u>Explanation</u>:
A transformer that reduces high voltage to low voltage is called a step-down transformer. The step-down transformers are that transformers which have high turns on its primary coils than secondary.
Where
Vp = Voltage in Primary Coil
Ip = Current in Primary Coil
Vs = Voltage in Secondary Coil
Is = Current in Secondary Coil

From laws of motion:
Where S is the distance/displacement (as you would call it) which is unknown
v = final velocity which is 0m/s (this is because the car stops)
u = initial velocity which is 36m/s (from the data given)
t = time taken for the distance to be covered and it is 6s
Substitute the values, hence:
But this is merely the distance he travelled in the 6 seconds he was trying to stop the car.
Therefore, the distance between the car and the cows = 160-108
Distance = 52m

Answer:
Decreasing in altitude and increasing in velocity
Explanation:
The formula for potential energy is:
where m is mass, g is constant gravitational energy and h is the potential altitude.
The formula for kinetic energy is:
where v is the velocity
Since m,g are constant, to convert from potential energy to kinetic energy, h must decreases while v increases. For example dropping an object from a height.
