Ethan dives 10 meters into the Atlantic Ocean. How much pressure does he experience?

2 answers:

6 0

The answer is A. 1 atm.

Solution:

Pressure in terms of height can be calculated using the formula:

P = pgh

where: p = density (kg/m^3); g = gravitational constant (m/s^2); h = height (m)

Using SI units: P = 1000(kg/m^3)*9.81(m/s^2)*10(m) = 98,100 Pascals

Convert Pascals to atm:

98,100 Pa (1 atm/101325 Pa) = 0.968 atm = rounded up to 1 atm

I attached a Diagram for this problem.

We star considering the system is in equlibrium, so

Fm makes $90-(\theta+5)$ with vertical

Fm makes 70 with vertical

Applying summatory in X we have,

$\sum F_x = 0$

$W+1.4-Fm cos(70)$

We know that W is equal to

$W= 0.06*100N = 6N$

Substituting,

$Fm cos (70) = W+1.4N$

$Fm cos (70) = 6N + 1.4N$

$Fm = \frac{7.4}{cos(70)}$

$Fm = 21.636N$

For the second part we know that the reaction force Fj on deltoid Muscle is equal to Fm, We can assume also that $\beta = \theta$

Answer:

moving the circuit or the magnet gives the same result

Explanation:

The faraday effect establishes that the temporal variation of imaginative flow produces an electric potential

fem = $\frac{d \phi }{dt}$ dfi / dt

the magnetic flux is

Ф = B. A = B A cos θ

suppose for simplicity that the angle is zero so cos 0 = 1

Φ = B A

By analyzing this expression, the change in magnetic flux can converge while keeping the magnetic field fixed and varying the electric field or keeping the electric field fixed and varying the magnetic field.

Consequently moving the circuit or the magnet gives the same result
