Answer: Sea otter is the pioneer species in the kelp forest as it regulates and controls the population of other species in the kelp forest.

Explanation:

If sea otters are hunted and their population is brought to extinction then this will cause major harm the ecosystem of the kelp forest and it will disturb the ecological balance in the kelp forest. The herbivorous animals consumed by the sea otters will increase in population and they will consume a lot of vegetation in the forest. The kelp forest which forms the coastline will not remain effective in providing protection against the storms to the neighboring areas.

Answer:

The magnitude of the magnetic force acting on the conductor is 0.75 Newton

Explanation:

The parameters given in the question are;

The length of the straight segment of wire, L = 25 cm = 0.25 m

The current carried in the wire, I = 5 A

The orientation of the wire with the magnetic field = Perpendicular

The strength of the magnetic field in which the wire is located, B = 0.60 T

The magnetic force, 'F', is given by the following formula;

F = [tex]\underset{I}{\rightarrow }[/tex]·L×[tex]\underset{B}{\rightarrow }[/tex] = I·L·B·sin(θ)

Where;

[tex]\underset{I}{\rightarrow }[/tex] = The current flowing, I

L = The length of the wire

[tex]\underset{B}{\rightarrow }[/tex] = The magnetic field strength, B

θ = The angle of inclination of the conductor to the magnetic field

Where I = 5 A, L = 0.25 m, B = 0.60 T, and θ = 90°, we get;

F = 5 A × 0.25 m × 0.60 T × sin(90°) = 0.75 N

Therefore

The magnitude of the magnetic force, F = 0.75 N.

Answer:

yes

Explanation:

The specific heat of the copper pan is the lowest among the other given pans. Therefore, a copper pan should carter used that will heat up and cool down the fastest. Therefore, option (A) is correct.

Specific heat of a substance can be described as the heat energy required to raise the temperature of one unit mass of a material by 1 °C. The S.I. unit of the specific heat capacity of a material is J/g°C.

The thermal capacity of a substance is a physical characteristic of a substance so it depends upon the nature of the material.

The mathematical expression of specific heat can be represented as :

Q = m×C× ΔT        Where C is the specific heat.

The specific heat is an intensive characteristic of a material and does not depend upon the shape or size of the quantity.

As given the values of the specific heat of metals of the frying pans, the highest specific heat means that the pan will take more heat to increase just one-degree temperature. As copper has the lowest specific heat so it can easily heat up in comparison to other pans.

Answer:

the final velocity of the skater after throwing the snowball is 3.17 m/s.

Explanation:

Given;

mass of the ice skater, m₁ = 72 kg

initial velocity of the ice skater, u₁ = 3.1 m/s

mass of the snowball, m₂ = 0.21 kg

initial speed of the snowball, u₂ = 28.0 m/s

Let the final velocity of the skater after throwing the snowball = v

Apply the principle of conservation of linear momentum to determine v;

m₁u₁ + m₂u₂ = v(m₁ + m₂)

72 x 3.1   +  0.21 x 28  = v(72 + 0.21)

229.08 = v(72.21)

v = 229.08 / 72.21

v = 3.17 m/s

Therefore, the final velocity of the skater after throwing the snowball is 3.17 m/s.

Answer:

The density of the 1,000,000 kg iceberg = The density of the 10 g iceberg

Explanation:

The given quantities of iceberg that will be the basis of the comparison of the densities of the iceberg;

The mass of the iceberg = 1,000,000 kg

The mass of the ice cube taken from the iceberg = 10 g

The density of a substance, is the measure of the mass of the substance per volume of the substance, it is a constant for the substance

[tex]Density = \dfrac{Mass}{Volume}[/tex]

For the iceberg, the density of the iceberg is the property that indicates the volume occupied by a given mass of the iceberg

Because of density, we can estimate that the volume occupied by a 1,000 kg iceberg is 10 times the volume occupied by a 100 kg iceberg

We can write

The density of the 100 kg iceberg = 100 kg/(x m³)

The density of the 1,000 kg iceberg = 1,000 kg/(10 × x m³) = 100 kg/(x m³)

Therefore, the density of the 100 kg iceberg = The density of the 1,000 kg iceberg

Similarly,

The density of the 1,000,000 kg iceberg = The density of the 10 g iceberg because the 10 g iceberg was obtained from the 1,000,000 kg iceberg, and therefore, they have the same density.

[tex]m_5[/tex] = Mass of uranium 235 ion = [tex]3.9\times 10^{-25}\ \text{kg}[/tex]

v = Velocity of ions = [tex]3\times 10^5\ \text{m/s}[/tex]

q = Charge of triply charged ions = [tex]3\times 1.6\times 10^{-19}\ \text{C}[/tex]

B = Magnetic field = 0.25 T

The force balance is

[tex]\dfrac{mv^2}{r}=qvB\\\Rightarrow r=\dfrac{mv}{qB}[/tex]

The difference between the radius of the ions are

[tex]\Delta r=(m_8-m_5)\dfrac{v}{qB}\\\Rightarrow \Delta r=\dfrac{(3.95\times 10^{-25}-3.9\times 10^{-25})\times 3\times 10^5}{3\times 1.6\times 10^{-19}\times 0.25}\\\Rightarrow \Delta r=0.0125\ \text{m}[/tex]

Separation is given by
