Answer:
The pH scale was invented by Svante Arrhenius is false.
Explanation :
because the pH scale was invented by Soren Sorensen
Answer:

Explanation:
The bike's acceleration can be found by using the following suvat equation:

where
v is the final velocity of the bike
u is the initial velocity
a is the acceleration
s is the distance covered
For the bike in the problem,
u = 0
v = 7 m/s
d = 40 m
Solving the equation for a, we find the acceleration:

SI units for volume don't care whether you use them to describe
a solid, a liquid, a gas, or a volume of vacuum.
The units are the liter, and the cubic meter (1,000 liters).
we are given in the problem the following dimensions or specifications
B = 0.000055 T r = 0.25 m constant mu0 = 4*pi*10-7
The formula that is applicable from physics is
B = mu0*I/(2*pi*r) I = 2*B*pi*r/mu0 I = 68.75 Amperes
