The HR diagram is based on brightness and temperature. If you want, you can search up the diagram. Most people classify the sides as Good For You and Bad for you, the bottom would be taste great and taste awful, but the answer is most likely brightness and temperature. Hope this helps you. :)
when object is placed on inclined plane then we will have net force along the inclined plane which is due to the component of weight along the incline
so we can say that


now in order to find the acceleration we can use Newton's II law




and the direction is along the inclined plane downwards as weight always pull downwards
So correct answer will be
<em>B)4.0m/s2, directed down the slope</em>
<span>In this situation when using newton's third law, the floor is very rigid and thus when we fall the floor applies
the same amount of force on us with which we were falling on it. The rigidness of the concrete floor makes it difficult for it to absorb some of our force. On the other hand sand is not rigid on impact sine it changes its shape while it absorbs a
large amount of our falling force and a small fraction of this
force is applied on is. That is why we don't get hurt</span>
Answer:
formula: A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.
This isn’t anything related to physics dude
