Answer:

125 joules

Explanation:

The velocity of the runner having a mass of 75 kg will be 9.93 m/s.

The energy of the body by virtue of its motion is called its kinetic energy.

Given is velocity of a runner who has a mass of 75 kg and 3,700 Joules of energy.

The kinetic energy of the body is given by the following formula -

KE = 1/2 mv².

Substituting the values -

3700 = 1/2 x 75 x v²

7400 = 75 x v²

v² = 7400/75

v² = 98.66

v = 9.93 m/s

Therefore, the velocity of the runner having a mass of 75 kg will be 9.93 m/s.

Answer:

Dorsal side:B

Ventral side:D

Anterior end:A

Posterior end:C

Explanation:

The four regions of the earthworm are, A is the anterior end,B is the dorsal side, C is the posterior end, and D is the ventral side.

Earthworms are common soil dwellers who are both safe and useful. Earthworms help plants flourish by collapsing dead and decaying organic debris into rich humus soil.

They also aerate the soil and enhance flow by digging small canals and holes.

The four regions of the earthworm are;

A is the Anterior end

B is the Dorsal side

C is the Posterior end

D is the Ventral side

Hence all the regions are clearly defined with the help of digrame.

Answer:

Efficiency = 71%

Explanation:

Given the following data:

Output energy = 250 Joules

Input energy = 350 Joules

To find efficiency;

[tex] Efficiency = \frac {Out-put \; energy}{In-put \; energy} * 100 [/tex]

Substituting into the equation, we have;

[tex] Efficiency = \frac {250}{350} * 100 [/tex]

[tex] Efficiency = 0.7143 * 100 [/tex]

Efficiency = 71.43 ≈ 71%

Therefore, the efficiency of the candle is 71 percent.

Answer: D- Each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA

Explanation:

A macromolecule is a large molecule that is made of many smaller units. Chromosomes are macromolecules that contain all of the genetic information in a cell. Chromosomes are each made of two smaller units called chromatids. Chromatids are each made up of molecules of DNA. Therefore, the correct description of the hierarchy of genetic material in a cell is that each chromosome in a cell is made up of two chromatids, which are each made up of molecules of DNA. The structures become more and more microscopic as one moves down the hierarchy.

The frequency that the driver (observer) detects is equal to 1008 Hz

Given the following data:

To calculate the frequency that the driver (observer) detects, we would apply Doppler's effect of sound waves:

Mathematically, Doppler's effect of sound waves is given by the formula:

[tex]F_o = \frac{V \;+ \;V_o}{V\; - \;V_s} F[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]F_o = \frac{343 \;+ \;20}{343\; - \;20} \times 900\\\\F_o = \frac{363}{323} \times 900\\\\F_o = 1.12 \times 900\\\\F_o =1008 \;Hz[/tex]

Driver (observer) frequency = 1008 Hz

Answer:

Temperature or thermal energy.

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Hence, the temperature or thermal energy of matter depends on how much the particles are moving, which depends on the amount of kinetic energy the particles possess.​

Answer:

a)       a = 3.72 m / s², b)    a = -18.75 m / s²

Explanation:

a) Let's use kinematics to find the acceleration before the collision

             v = v₀ + at

as part of rest the v₀ = 0

             a = v / t

Let's reduce the magnitudes to the SI system

              v = 115 km / h (1000 m / 1km) (1h / 3600s)

              v = 31.94 m / s

              v₂ = 60 km / h = 16.66 m / s

l

et's calculate

             a = 31.94 / 8.58

             a = 3.72 m / s²

b) For the operational average during the collision let's use the relationship between momentum and momentum

            I = Δp

            F Δt = m v_f - m v₀

            F = [tex]\frac{m ( v_f - v_o)}{t}[/tex]

            F = m [16.66 - 31.94] / 0.815

            F = m (-18.75)

Having the force let's use Newton's second law

            F = m a

            -18.75 m = m a

             a = -18.75 m / s²

Answer:

Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”

Explanation:

Volcanoes are found around tectonic plates because the convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other, plates converge and the plates move together, also known as ridge push, therefore mountains and volcanoes are formed
