Athens was known for its love of pottery , the sculptures , and architecture
I hope that's help !
In series circuit, Req = R₁ + R₂ + R₃ + ···
In parallel circuit,
<h3>Q7.</h3>
total resistance in the upper branch = R₂ + R₃ = R₂ + 2
R₂ + 2 = 12
R₂ = 10Ω
<h3>Q8.</h3>
Req = 1.7Ω
Answer:
3rd one
Explanation:
they are pointing right 2 left because most things start at the right in which even if the force of both direction is the same, it acquires more force. i learned this from my science teacher yesterday in Zoom
The work done by a force is equal to:
where
W is the work
F is the force applied
d is the distance through which the force is applied.
In our problem, the force needed to lift the dog is equal to the weight of the dog:
F=24 N
and the dog is moved through a distance of
d=4.8 m
therefore, the work done by the child to lift the dog is
