In order to find it's square root, we could make it into two square roots.
Let us find the square roots of both radicals seprately.
Each pair of a number inside square root gives a number out .
Therefore,

False.
Unweathered rock that underlies soul is known as bedrock.
A) 1153 N/m
We can find the spring constant by using Hooke's law:
where
F is the force applied to the spring
k is the spring constant
x is the displacement of the spring
In this problem, a fish of mass m = 4.0 kg is hanging on the spring, so the force applied is the weight of the fish:
and the displacement of the spring is:
so, the spring constant is
B) 16.8 cm
In this case, a fish of mass
m = 8.0 kg
is hanging on the spring. Therefore, the force applied to the spring is
So we can find the displacement of the spring:
And since the equilibrium length of the spring is
the new length of the spring will be
Given Information:
Magnetic field = B = 1×10⁻³ T
Frequency = f = 72.5 Hz
Diameter of cell = d = 7.60 µm = 7.60×10⁻⁶ m
Required Information:
Maximum Emf = ?
Answer:
Maximum Emf = 20.66×10⁻¹² volts
Explanation:
The maximum emf generated around the perimeter of a cell in a field is given by
Emf = BAωcos(ωt)
Where A is the area, B is the magnetic field and ω is frequency in rad/sec
For maximum emf cos(ωt) = 1
Emf = BAω
Area is given by
A = πr²
A = π(d/2)²
A = π(7.60×10⁻⁶/2)²
A = 45.36×10⁻¹² m²
We know that,
ω = 2πf
ω = 2π(72.5)
ω = 455.53 rad/sec
Finally, the emf is,
Emf = BAω
Emf = 1×10⁻³*45.36×10⁻¹²*455.53
Emf = 20.66×10⁻¹² volts
Therefore, the maximum emf generated around the perimeter of the cell is 20.66×10⁻¹² volts
