Answer:
necessary for the growth, development and repair of all body tissues. it's involved in many body functions, including formation of collagen, absorption of iron, the proper functioning of the immune system, wound healing, and the maintenance of cartilage, bones, and teeth.
Explanation:
Answer:
Shorter than(?)
Explanation:
What is it that you're looking for here? Is it just some random fill in the blank question?
My guess is that the horizontal distance has to be shorter than that of the ladder length because if it wasn't then the ladder would be laying down or maybe standing straight up... and you can't really use it normally like that... I'm sorry, where is the Physics in this question exactly?
Answer:
c. 0.71 [s]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 0 (because when the ball reaches the top, there is no movement)
Vo = initial velocity = 7 [m/s]
g = gravity acceleration = 9.81 [m/s²]
t = time [s]
Note: The negative sign of the equation means that the movement is againts the direction of the gravity acceleration.
![0 = 7 - (9.81*t)\\t = 0.713 [s]](https://tex.z-dn.net/?f=0%20%3D%207%20-%20%289.81%2At%29%5C%5Ct%20%3D%200.713%20%5Bs%5D)
Answer: Option (a) is the correct answer.
Explanation:
A formula that represents how atoms are linked or joined together is known as a structural formula.
For example, the model given in the image (in question) represents arrangement of all the atoms. Therefore, it is a structural formula.
Whereas a chemical formula represents a compound along with ratio of compounds.
A space filling model and a ball-stick model is a three dimensional model. In space filling model atoms are represented by spheres whereas in ball stick model atoms are represented by ball and bonds are represented by stick.
Answer:
The weight of an object would be less on the moon than on the earth
Explanation:
Thus, our object has mass m both on the surface of the Earth and on the surface of the Moon, but it will weigh much less on the surface of the Moon because the gravitational acceleration there is a factor of 6 less than at the surface of the Earth.
