Stars are formed in <u>nebulas</u>, interstellar clouds of dust and gas.
Answer:
A
Explanation:
Wattage = E * I
E = 25
I = 5
Wattage = 25 * 5
Wattage = 125
The secondary, in an ideal transformer has the same wattage.
125 = 50 * I Divide by 50
125/50 = I
I = 2.5
A :-) a = v^2 by r
Given - radius = 25 m
velocity = 10 m/s
Solution -
a = v^2 by r
a = ( 10 )^2 by 25
a = 100 by 25
( cut 25 and 100 because 25 x 4 = 100 )
a = 4 m/s^2
.:. The centripetal acceleration of the car
= 4 m/s^2.
A) it is always changing direction
