Answer:

Explained

Explanation:

Both silver and copper are placed in the same group in the periodic table. In the D block. The elements in the same group have almost similar physical and chemical properties.

Both element have only one electron in their outer shell. Both are very good conductor of electricity and heat. Both are ductile in nature as both can be drawn into wire. The atomic number of Cu is 29 and that of the Ag is 47. Both are highly malleable in nature.

Which of these will have the same units of pressure is multiplied by area? Velocity time force or pressure

choli [55]

Considering the definition of pressure, force will have the same units of pressure is multiplied by area.

<h3>What is pressure</h3>

Pressure is defined as the force exerted per unit area.

In this way, for the same force, the pressure is inversely proportional to the surface: this means that, for the same force, the smaller the surface, the greater the pressure exerted and the more the body will be deformed.

That is, pressure is defined as the force exerted perpendicularly on a surface and is expressed mathematically as:

$Pressure=\frac{Force}{Area}$

In the International System of Units, the unit of pressure is the pascal (Pa). One pascal is the pressure exerted by a force of 1 N distributed over an area of 1 m².

Then, the definition of force can be expressed as:

Force= Pressure× Area

<h3>Summary</h3>

In summary, force will have the same units of pressure is multiplied by area.

What is the difference between speed and velocity?

avanturin [10]

Answer:

speed is the rate of change in distance thus it is scalar physical quantity

while velocity is the rate of change in displacement thus it is a vector physical quantity

Explanation:

vector physical quantity: is a quantity that requires both magnitude and direction to identify

scalar quantity: requires only magnitude to identify.

A child throws a baseball directly upward. What are the signs of the velocity and acceleration of the ball at the very top of th

Anastaziya [24]

Answer:

velocity zero and acceleration negative

Explanation:

According to the directions taken in the vector analysis, the direction which is upwards taken as positive, the direction which is downwards is taken as negative.

The direction which is rightwards taken as positive and the direction which is leftwards taken as negative.

here, ball throws vertically upwards and it attains a maximum height. At maximum height the magnitude of velocity is zero but the acceleration is always acting downwards so it is taken as negative in sign.

Which two options are forms of kinetic energy?

juin [17]

Answer:

B. Thermal energy

E. Sound energy

Explanation:

Thermal and sound energy is kinetic energy.

Kinetic energy is the energy that results as a function of the motion of a body or the particles of the medium.

Sound energy is transmitted by the vibration of the particles in the air. The vibration leads to movement of the particles and hence, kinetic energy is produced.

Thermal energy originates as a result of the temperature differences in a body. This temperature difference leads to the increase in the kinetic energy of some particles which also causes vibration and motion of the particles.
