The distance covered is 115 m
Explanation:
The motion of Ileana is a uniformly accelerated motion (constant acceleration), therefore we can use the following suvat equation:
where
s is the distance covered
u is the initiaal velocity
v is the final velocity
t is the time elapsed
In this problem, we have:
u = 4.20 m/s
v = 5.00 m/s
t = 25.0 s
Therefore, we can re-arrange the equation to find the distance covered:

Answer:
Series combination:
Equivalent resistance =10Ω
Parallel combination:
Equivalent resistance
Explanation:
Resistance: Resistance is the ratio of voltage to the current.
R = resistance
I = current
V= potential difference(voltage)
There are two types of resistance combinations.
Series combination: If the ending point of one resistance is connected to the starting point of other resistance that combination is known as series combination.
If R₁,R₂ and R₃ are connected in series combination.
Then equivalent resistance = R₁+R₂+R₃
Parallel combination: If the ending point and the starting point of the all resistance are the same points that combination is known as parallel combination.
If R₁,R₂ and R₃ are connected in parallel combination.
Then equivalent resistance
Here R₁=7Ω and R₂=3Ω
If R₁ and R₂ connected in series combination
Then equivalent resistance = (7+3) Ω
=10Ω
If R₁ and R₂ connected in parallel combination
Then equivalent resistance
