Speed = Distance ÷ Time
Speed = 116 ÷ 29
Speed = 4
Electric current is the flow of charge due to the potential difference between two terminals per unit time. It is denoted by I and its unit is amp. It can be mathematically expressed as I=Q/t.
If this isn’t what your looking for I need the options they gave you
Series,effective resistance =R₁+R₂+R₃...
parallel,effective resistance 1/R=1/R₁ +1/R₂ +1/R₃...
Here,effective resistance 1/R =1/7 +1/5+ 1/4+1/2
=1.092
R = 1/1.092 =0.915Ω
voltage V=9 V
current I=V/R
I=9 / 0.915
=9.83 A
False
If all other factors, such as medium, are kept the same, longitudinal waves tend to be stronger.
