<span>Contemporary skepticism (or scepticism) is loosely used to denote any questioning attitude,[1] or some degree of doubt regarding claims that are elsewhere taken for granted.[2] Usually meaning those who follow the evidence, [ [ versus those who are skeptical of the evidence (see:Denier) Skepticism is most controversial when it questions beliefs that are taken for granted by most of the

A voltaic cell with an aqueous electrolyte is based on the reaction between Cd2+(aq) and Mg(s), producing Cd(s) and Mg2+(aq). Wr
Monica [59]

Answer : The balanced two-half reactions will be,

Oxidation half reaction (anode) : Mg(s)\rightarrow Mg^{2+}(aq)+2e^-

Reduction half reaction (cathode) : Cd^{2+}(aq)+2e^-\rightarrow Cd(s)

Thus the overall reaction will be,

Mg(s)+Cd^{2+}(aq)\rightarrow Mg^{2+}(aq)+Cd(s)

Explanation :

Voltaic cell : It is defined as a device which is used for the conversion of the chemical energy produces in a redox reaction into the electrical energy. It is also known as the galvanic cell or electrochemical cell.

The given redox reaction occurs between the magnesium and cadmium.

In the voltaic cell, the oxidation occurs at an anode which is a negative electrode and the reduction occurs at the cathode which is a positive electrode.

The balanced two-half reactions will be,

Oxidation half reaction (anode) : Mg(s)\rightarrow Mg^{2+}(aq)+2e^-

Reduction half reaction (cathode) : Cd^{2+}(aq)+2e^-\rightarrow Cd(s)

Thus the overall reaction will be,

Mg(s)+Cd^{2+}(aq)\rightarrow Mg^{2+}(aq)+Cd(s)

If a car has an initial velocity of 20 m/s and accelerates at 2.0 m/s2 for 100 m, what is its final velocity?
rodikova [14]

Answer:

28.28 ms-1

Explanation:

v² = u² + 2as

v² = 20² + 2×2×100

v²= 800

v = 28.28 ms-1

Use the accompanying seismogram to answer which of the three types of seismic waves reached the seismograph first.
UkoKoshka [18]

Answer:

Primary waves (P-waves)

Explanation:

Due to excess of the energy inside the earth when the tectonic plates begin to slide or fracture then the energy is released in the form of seismic waves, this causes the earthquake.

<u>Two types of seismic waves are generally responsible for the earth quakes:</u>

  1. body waves
  2. surface waves

Body waves are of two types:

Primary waves (P-waves)

These are the fastest of all the waves involved in the earth-quake which travel at a speed of 1.6 km to 8 km per second.

They can pass trough solids, liquids and gases. They arrive at the surface as an instant thud.

Secondary waves (S-waves)

They can only pass through the solids and they move slower than the P-waves.

As S-waves move, they displace the rock particles, pushing them outwards perpendicular to the wave-path that leads to the earthquake-related first rolling period.

Surface waves (L-waves/ long waves)

  • These waves move along the surface of the earth. They are responsible for the earthquake's carnage.
  • They move up and down the Earth's surface, rocking the foundations of man-made structures.
  • Surface waves are slowest of the three waves, which means that they are the last to arrive. So at the end of an earthquake usually comes the most powerful shaking.
