The time taken, t = 2 seconds, can be deduced from the scenario involving the fish being lifted.

Sharks are generally negatively buoyant; the upward buoyant force is less than the weight force. This is one reason sharks tend
Ostrovityanka [3204]
The required lift force is approximately 866.92 N. To determine this, we first establish the shark's mass at 92 kg and its density at 1040 kg/m³. The volume of the shark is calculated by dividing mass by density, yielding 0.08846 m³. The buoyant force acting on the shark is then determined by multiplying the volume by the density of water and gravity, resulting in a lift force of 866.92 N.

serg [3582]

Answer:

4.1\cdot 10^8 N

Explanation:

To begin with, we must determine the pressure acting on the sphere, which is calculated using:

p=p_0 + \rho g h

where

p_0 =1.01\cdot 10^5 Pa denotes the atmospheric pressure

\rho = 1000 kg/m^3 represents the density of the water

g=9.8 m/s^2 signifies the acceleration due to gravity

h=11,000 m indicates the depth

By substituting these values,

p=1.01\cdot 10^5 Pa + (1000 kg/m^3)(9.8 m/s^2)(11,000 m)=1.08\cdot 10^8 Pa

The sphere's radius is calculated as r = d/2 = 1.1 m/2 = 0.55 m

Thus, the sphere's total surface area can be expressed as

A=4 \pi r^2 = 4 \pi (0.55 m)^2=3.8 m^2

Consequently, the inward force acting on the sphere equals

F=pA=(1.08\cdot 10^8 Pa)(3.8 m^2)=4.1\cdot 10^8 N

A square loop of wire with initial side length 10 cm is placed in a magnetic field of strength 1 T. The field is parallel to the
kicyunya [3294]

Answer:

Induced EMF is 2 x 10⁻³ volts

Explanation:

B = strength of the magnetic field aligning with the loop's axis = 1 T

\frac{dA}{dt} = area change rate of the loop = 20 cm²/s = 20 x 10⁻⁴ m²

θ = the angle formed by the magnetic field and area vector = 0

E = the induced EMF across the loop

EMF can be calculated using the formula

E = B \frac{dA}{dt}

E = (1) (20 x 10⁻⁴ )

E = 2 x 10⁻³ volts

E = 2 mV
