In drawing, when the quality of a single line changes from thick to thin, it is referred to as calligraphic. Calligraphy is an art that is associated with writing. It involves designing and executing a lettering using a broad tip instrument or a brush. Pens that are used for this uses nibs which can be pointed, round or flat.

Answer:

Calligraphic

Explanation:

Calligraphy is originally a form of writing, it is a form of lettering in which an instrument (could be a pen or a brush with a flat tip) with a broad tip is used to design or draw. In calligraphy, the quality of a line changes from thick to thin and sometimes back to thick.

Answer:

Global warming pollution

When we burn oil, coal, and gas, we don't just meet our energy needs—we drive the current global warming crisis as well. Fossil fuels produce large quantities of carbon dioxide when burned. Carbon emissions trap heat in the atmosphere and lead to climate change

What is the term for the depth of the water needed to float a boat?

mina [271]

<span> The term for the depth of the water needed to make a boat afloat is called the draft of the boat. It can be measured as the distance from the water surface down the lowest point of the vessel. It can be imagined as the submerged portion of the boat during navigation.</span>

Suppose a 65 kg person stands at the edge of a 6.5 m diameter merry-go-round turntable that is mounted on frictionless bearings

ozzi

Answer:

$0.3165\ \text{rad/s}$

Explanation:

m = Mass of person = 65 kg

d = Diameter of round table = 6.5 m

r = Radius = $\dfrac{d}{2}=3.25\ \text{m}$

v = Velocity of person running = 3.8 m/s

$I_t$ = Moment of inertia of turntable = $1850\ \text{kg m}^2$

Moment of inertia of the system is

$I=I_t+mr^2\\\Rightarrow I=1850+65\times 3.25^2\\\Rightarrow I=2536.5625\ \text{kg m}^2$

As the angular momentum of the system is conserved we have

$L_i=L_f\\\Rightarrow mvr=I\omega_f\\\Rightarrow \omega_f=\dfrac{mvr}{I}\\\Rightarrow \omega_f=\dfrac{65\times 3.8\times 3.25}{2536.5625}\\\Rightarrow \omega_f=0.3165\ \text{rad/s}$

The angular velocity of the turntable is $0.3165\ \text{rad/s}$ .

g Let the orbital radius of a planet be R and let the orbital period of the planet be T. What quantity is constant for all plane

Wittaler [7]

Explanation:

Kepler's third law gives the relationship between the orbital radius and the orbital period of the planet. Its mathematical form is given by :

$T^2=\dfrac{4\pi ^2}{GM}a^3$

Here,

G is gravitational constant

M is mass of sun

It means that the mass of Sun is constant for all planets orbiting the sun, assuming circular orbits.
