A crystalline substance that contains water molecules is a ___. <em><u>hydrate</u></em>
<u>Answer:</u>
<em>The outside edge of a spinning compact disc moves with a higher velocity than the inner track of the disc.</em>
<u>Explanation:</u>
Here the compact disc undergoes rotational motion about a fixed axis which is its centre in this case. The particles in rotational motion have angular velocity which is given by the equation
ω = ∅/t
Where θ is the angular displacement and t is the time.
The transnational speed of a particle which is in circular motion is given by the equation
v = rω
r is the distance of the point from the rotation centre
The transnational speed of the particles is merely determined by their distance from the centre in this case. It is due to the equality of angular velocity of all the points.
The distance of the outer edge of the compact disc from its rotational centre is larger than the distance of inner edge from the rotational centre. Thus the farther edge of a spinning disc moves faster than the nearer edge.
Answer:
Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. When organisms face limiting factors, they show logistic growth (S-shaped curve, curve B: Figure below). ... Limiting factors determine the carrying capacity of a population.
Explanation:
Answer:
Involuntary muscle action are muscles that move WITHOUT conscious control, and voluntary muscle action are muscles that move WITH conscious control.
Explanation:
A example of a involuntary muscle action would be your heart. Your heart is a muscle beats without you thinking about it and is very vital to your body. A example of a voluntary muscle would be the muscles that are attached to your bones and allow you to move your body, and it's voluntary because your body won't move on it's own.
Hope this helps.
