-- What's the volume of a cylinder with radius=1m and height=55m ?
( Volume of a cylinder = π R² h )
-- How much does that volume of water weigh ?
1 liter of water = 1 kilogram of mass
Weight = (mass) x (acceleration of gravity)
-- What's the area of the bottom of that 1m-radius cylinder ?
Pressure = (force) / (area)
B strength training I think that’s the answer
Answer:
A scientific hypothesis must be tetable so it can become a scientific theory.
Explanation: I think
Answer:
The magnitude of the resultant of the magnetic field is
Explanation:
Given that,
Current = 40 A
Magnetic field
Distance = 22 cm
We need to calculate the magnetic field
Using formula of magnetic field
Where, r = distance
I = current
Put the value into the formula
We need to calculate the magnitude of the resultant of the magnetic field
Using formula of resultant
Put the value into the formula
Hence, The magnitude of the resultant of the magnetic field is
