Explain why a bolt of lightning is like the spark you might see when you touch a metal object and get a shock.
Cerrena [4.2K]

Answer:

Just like lightning, the spark you see is the discharge of static electricity that equalizes the charges.  When you touch a metal object and get a shock, electrons are travelling in between you and the object to equalize the charges of the two objects.  The light that is seen is the plasma created by electrons jumping between objects which heats the air surrounding them.

Give a specific example of a scalar or vector quantity. Explain why thus type of quantity is used to describe this event.
dlinn [17]

Example of scalar: speed. Example of vector: velocity

Explanation:

In physics, there are two types of quantities:

- Scalar: a scalar quantity is a quantity having only magnitude, so it is just a number followed by a unit. Examples of scalar quantities in physics are:

Mass

Time

Speed

- Vector: a vector quantity is a quantity having both a magnitude and a direction. Examples of vector quantities in physics are:

Force

Acceleration

Velocity

The two types of quantities can be used in the same event, but in a different way. One of the most common example is the difference between speed and velocity.

In fact, let's consider an object moving in a uniform circular motion: it means that it is moving in a circle at a constant speed. The speed of the object measures only how fast the object is moving, but without telling anything about its direction of motion. The velocity, viceversa, also takes into account the direction of motion, and exactly for this reason, the velocity in a uniform circular motion is not constant, because the direction (it is a vector) is constantly changing. So, in a uniform circular motion, the speed is constant but the velocity is not.

When energy is added to a fl uid, the temperature of the fl uid increases. an equation describing this phenomenon is:_________
Ksju [112]

The temperature of a fluid rises when energy is given to it. This phenomenon can be described by the equation:

Q = MCp ΔT

where,

Q is the quantity of added energy.

M is the fluid's mass.

The fluid's heat capacity is denoted by Cp.

T stands for temperature change.

<h3>What happens to a fluid's kinetic energy as the temperature rises?</h3>

The mean kinetic energy of the particles in a liquid rises with temperature. The molecules' higher average kinetic energies allow them to more easily overcome the attraction forces that keep them bound together.

<h3>Which temperature rise makes liquids more fluid?</h3>

The most significant determining factor for fluidity is pouring temperature. Therefore, the fluidity increases as the pouring temperature increases.

<h3>How does a liquid react when the temperature rises?</h3>

Particles in a solid, liquid, or gas move more quickly as its temperature rises. The particles slow down as the temperature drops. When a liquid is sufficiently cooled, it turns into a solid.

A stone is dropped into a lake, creating a circular ripple that travels outward at a speed of 50 cm/s. Find the rate at which th
Drupady [299]
The radius of the circle, in cm, after t seconds would be 50t 
The area, A, of the circle after t seconds is expressed in the equation: A = pi * r^2 
A = pi * (50T)^2 = pi*2500*t^2 
The change of area per unit time is obtained by differentiating the equation
A' = pi*2500*2*t A' = pi*5000*t
when t = 3 secondsA' = pi*5000*3 = 47122 cm2/s
