Data organization is extremely important in science. One must be able to display data in a way that others can look at it and easily understand what's being said. This takes us to line charts, which are great for showing how something increases or decreases over an amount of time. Another example would be a pie chart which could show the percentages of different matter that makes up a full object.

1. The arctic tern flies from the Arctic to the Antarctic and back every year, a total distance of 22,000 miles! In late summer,

NikAS [45]

Answer:

The average velocity that these birds travel is 122.22 miles per day to the south.

Explanation:

Speed is the physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed is a physical quantity that expresses the relationship between the space traveled by an object, the time used for it and its direction.

Speed is expressed mathematically as the quotient between distance and time:

$v=\frac{d}{t}$

where "v" is the speed of the mobile, "d" is the distance traveled by the mobile, and "t" is the time taken by the mobile to carry out the movement.

In this case:

d= 11,000 miles
t=3 months= 90 days ( considering that in 1 month there are 30 days)

Replacing:

$velocity=\frac{11,000 miles}{90 days}$

velocity = 122.22 $\frac{miles}{day}$

The average velocity that these birds travel is 122.22 miles per day to the south.

A parallel-plate capacitor with circular plates of radius R is being discharged. The displacement current through a central circ

Dvinal [7]

Answer:

The discharging current is $I_d = 36.8 \ A$

Explanation:

From the question we are told that

The radius of each circular plates is R

The displacement current is $I = 9.2 \ A$

The radius of the central circular area is $\frac{R}{2}$

The discharging current is mathematically represented as

$I_d = \frac{A}{k} * I$

where A is the area of each plate which is mathematically represented as

$A = \pi R ^2$

and k is central circular area which is mathematically represented as

$k = \pi [\frac{R}{2} ]^2$

So

$I_d = \frac{\pi R^2 }{\pi * [ \frac{R}{2}]^2 } * I$

$I_d = \frac{\pi R^2 }{\pi * \frac{R^2}{4} } * I$

$I_d = 4 * I$

substituting values

$I_d = 4 * 9.2$

$I_d = 36.8 \ A$

The law of conservation of energy states:

Alborosie

Answer:

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. ... For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes.
