Is it safer for a car to decelerate quickly or slowly? And why?

Answer:

The answer is "Rigor mortis".

Explanation:

When the very large volume will be that the progress of its postponed by calcium and magnesium. The causes brain intensification of a liver due to the change throughout the myofibrils within a week of dying of its organism. When anyone accidentally spilled a power cable into a rank for toads, one's tissue will be disrupted instantly by stringent deaths.

This is because the high frequency stimuli of the power line is causing rigor

mortis.

Rigor mortis is referred to as the stiffening of the body of animals when they

die and is usually caused by the body's glycogen and  ATP concentration

diminishing.

Rigor mortis can also be caused by a high frequency stimuli such as

exposure to electric current which hastens the conditions that causes it to

occur.

B. Must eat to get energy

Explanation:

The common characteristics of all consumers is that they must eat to get energy. This way, they are termed heterotrophs.

Heterotrophs are organisms that cannot make their own food. They must eat other organisms to obtain nutrition for energy needs.

Plants do not do this. They are autotrophs in that they simply make their own food.

They use this food to obtain energy for their living activities.

Answer:

 F = 1.2 10⁵ N

Explanation:

Force is defined by

          P = F / A

          F = P A

The area is

          A = π r²

the radius is half the diameter

          r = d / 2

          A = π d²/4

we substitute

          F = P π d²/4

let's calculate

          F = 145 10⁶  π (3.25 10⁻²)²/4

          F = 1.2 10⁵ N

Answer:

[tex]B=5\times 10^{-7}\ T[/tex]

Explanation:

Given that,

Current in a wire, I = 5 A

We need to find the magnetic field at 2m from a straight wire carrying a current of 5 A.

The magnetic field due to a wire is given by :

[tex]B=\dfrac{\mu_0I}{2\pi r}\\\\B=\dfrac{4\pi \times 10^{-7}\times 5}{2\pi \times 2}\\\\B=5\times 10^{-7}\ T[/tex]

So, the required magnetic field is [tex]5\times 10^{-7}\ T[/tex].

Answer:

38.7 °C.

The final temperature (reached by both copper and water) is 38.7 °C.

So the answer is probably C.

The heat energy lost by the metal piece is equal to the heat gained by the water in the cup. From this concept using calorimetric equation, their final temperature is equal to 30°C.

Calorimetric equation states the relation between heat energy absorbed or released by a system with the mass, specific heat capacity and temperature difference of the matter as written below:

q = m c Δ

Given, mass of copper piece = 0.50 kg

mass of water = 0.50 kg

c for Cu = 0.386 KJ/Kg °C

c for water = 0.418  KJ/Kg °C

The heat energy lost by copper metal is equal to the heat energy gained by water. Let T be the final temperature.

then,

0.50 kg × 0.386 KJ/Kg °C × (115°C - T) = 0.50 kg × 0.418 KJ/Kg °C × (T - 22°C).

2.09  (115°C - T)  = 0.193  (T  - 22°C).

2.09 T - 45.98 + 0.193 = 22.195

T = 30°C

Therefore, the final temperature of water and copper piece is 30 °C.

Answer:

see answer below

Explanation:

Before we do any kind of calculation, we need to convert the proper units of the exercise. All the units of distance must be in meters, so, let's change distance of the wire, and the magnetic field to meters:

Separation between the wires are 2.5 mm:

2.5 mm * (1 m / 1000 mm) = 0.0025 m

The distance of P from the bottom of the wires is 37 cm:

37 cm * (1 m/100 cm) = 0.37 m

The distance of P from the top of the wires is just the sum of the two distances:

R = 0.37 + 0.0025 = 0.3725 m

Now that we have the distance, we can determine the magnetic field, using the following expression:

B = B(bottom) - B(top)   or just B₂ - B₁

And B = μ₀ I / 2πR

Replacing in the above expression we have:

B = μ₀ I / 2π ( 1/R₂ - 1/R₁)

Now we can determine the magnetic field:

B = (4πx10⁻⁷ * 10 / 2π) (1/0.37 - 1/0.3725)

Which means that the magnetic field is out of the page.

Answer:

v = 8.09   m/s

Explanation:

For this exercise we use that the work done by the friction force plus the potential energy equals the change in the body's energy.

Let's calculate the energy

starting point. Higher

         Em₀ = U = m gh

final point. To go down the slope

         Em_f = K = ½ m v²

The work of the friction force is

         W = fr L cos 180

to find the friction force let's use Newton's second law

Axis y

        N - W_y = 0

        N = W_y

X axis

        Wₓ - fr = ma

let's use trigonometry

        sin  θ = y / L

         sin θ = 11/110 = 0.1

         θ = sin⁻¹  0.1

          θ = 5.74º

         sin 5.74 = Wₓ / W

         cos 5.74 = W_y / W

         Wₓ = W sin 5.74

         W_y = W cos 5.74

the formula for the friction force is

         fr = μ N

         fr = μ W cos θ

Work is friction force is

         W_fr = - μ W L cos θ  

Let's use the relationship of work with energy

        W + ΔU = ΔK

         -μ mg L cos 5.74 + (mgh - 0) = 0  - ½ m v²

        v² = - 2 μ g L cos 5.74 +2 (gh)

        v² = 2gh - 2 μ gL cos 5.74

let's calculate

        v² = 2 9.8 11 - 2 0.07 9.8 110 cos 5.74

        v² = 215.6 -150.16

        v = √65.44

        v = 8.09   m/s

Answer:

1) The charge on the outer shell is +4·Q

2) The charge on the inner shell is +Q

Explanation:

1) The given parameters of the spherical shell are;

The net charge on the spherical shell = 3·Q

The point charge surrounded by the spherical shell = -Q

Let 'x' represent the charge on the outer shell, and let 'y', represent the charge on the inner shell, we have;

The net charge, 3·Q = -q + x

∴ x = 3·Q + Q = 4·Q

The charge on the outer shell, x = 4·Q

2) The net charge in the shell is zero, therefore, the charge on the inner shell, 'y', is given as follows;

-Q + y = 0

∴ y = +Q

The charge on the inner shell, y = +Q

Answer:

 i₂ = ½ i₁

Explanation:

Let's write ohm's law for the first statement

           V = i₁ R

            i₁ = V / R

tells us that we change the resistance to R '= 2R

let's write ohm's law

            V = i₂ R’

indicates that V remains constant

            i₂ = V / R '

            i₂ = V / 2R

            i₂ = ½ V/R

we substitute

            i₂ = ½ i₁

Answer:

the speed of the body must be the same for the three hills regardless of their slope

             v = [tex]\sqrt{2gy}[/tex]

Explanation:

To shorten the answer to this exercise, let's use the concept of conservation of energy

starting point. Highest point of the hill

         Em₀ = U = m h y

final point. Lower part of the hill

         Em_f = K = ½ m v²

as there is no friction the mechanical energy is conserved

         Em₀ = Em_f

         mg y = ½ m v²

         v = [tex]\sqrt{2gy}[/tex]

Let's analyze this result, we see that the speed at the bottom of the hill depends only on the height of the hill, not on the slope, so the speed of the body must be the same for the three hills regardless of their slope

Answer:

A terrestrial planet.

Explanation:

Terrestrial planets (Inner planets) are closer to the sun then outer planets. No inner planet has rings and they are all composed of rocky material.

A terrestrial planet  planet is composed of rocky material, has no rings, and is closer to the sun.

Terrestrial planets are Earth-like planets having a hard surface consisting of rocks or metals. A molten heavy-metal core, few moons, and topographical features like valleys, volcanoes, and craters are also characteristics of terrestrial planets.

Mercury, Venus, Earth, and Mars are the four terrestrial planets in our solar system, and they also happen to be the four nearest to the sun.

There may have been more terrestrial planetoids during the solar system's formation, but they either combined or were obliterated.

The planets are not entirely terrestrial. Gas giants, also referred to as Jovian planets, include Jupiter, Saturn, Uranus, and Neptune in our solar system.

Hence, a  terrestrial planet  planet is composed of rocky material, has no rings, and is closer to the sun.
