Answer:

Granules

Explanation:

The outer most layer of the Earth is photo-sphere. The photo-sphere layer of the sun is characterized by many bright markings i.e. it has a grainy texture. These are called granules. Granules are produced due to convection currents. The top of the convection cells are visible which give it a grainy texture and is known as granulation.

What is a rumor wave ?
Radda [10]

Answer:

Following are the answer to this question:

Explanation:

The wave is propagating at the incident wave which focuses on the stretchy and rotational inertia features of the whole medium via a material system.  For both the mechanical waves there are many two basic types of incident waves: quality management program and transverse waves.

The rumor is also known as the "Norman Rockwell", in which the environment of some of the greatest physics attempts of our time, it pays to remain suspicious when remarkable reports of historical findings are made on social media.

yulyashka [42]

Answer:

a) 156960 N/m

b) Yes the player can play on the team.

Explanation:

F = Force

a = Acceleration due to gravity = 9.81 m/s²

m = Mass

k = Spring constant

x = Deformation length of spring

F = ma

From Hooke's law

F=kx\\\Rightarrow ma=kx\\\Rightarrow k=\frac{ma}{x}\\\Rightarrow k=\frac{120\times 9.81}{0.0075}\\\Rightarrow k=156960\ N/m

The effective spring constant is 156960 N/m

When x = 0.48 cm = 0.0048 m

m=\frac{kx}{a}\\\Rightarrow m=\frac{156960\times 0.0048}{9.81}\\\Rightarrow m=76.8\ kg

The mass of the player is 76.8 kg which is less than the required mass limit of the players' which is 85 kg. So, the player is eligible to play.
