The skeletal system is a body system comprised of bone structures and tissues that help hold the body up. It also gives the body its shape - as if it was the framework. On top of that, it protects internal organs within the body.
Therefore, the skeletal system is a body system comprised of bone structures and tissues that give the body its shape and protects internal organs.
Hope this helps!
Explanation:
Given that,
Mass of the cart,
Mass of the cart 2,
Final speed of cart 2,
Final speed of cart 1 is 0 as it comes to rest.
Let us assume that the initial velocity of the cart 2 is 0. So using the conservation of linear momentum as :
So, the initial velocity of the 1.0-kg cart is 0.9 m/s.
Answer:
dimension is 20ft*20ft*10ft
Explanation:
let a,a and h are length, width and height of given tank with square base.
volume = a*a*h
surface area =aa +2(ah+ah)
for weight to minimize, surface area is to be minimum i.e.
a = 20ft
now
at a = 20 ft
h = 10ft
hence dimension is 20ft*20ft*10ft

Answer:</h2>
(d) it is freely falling but it has a high tangential velocity.
<h2>
Explanation:</h2>
The Moon does not crash into the Earth because it is freely falling but it has a high tangential velocity, that is, actually the moon is falling toward the earth, but since it's moving so fast, then it will never hit the earth. The moon is so far away from the earth and move so fast that it falls around the earth in a continuous circular path. In other words, the high tangential velocity makes the moon to move around the earth. If the moon was moving slowly, gravity would make the moon to fall into the earth.
