Answer:
Tendon connects our muscles to our bones.
Explanation:
A tendon (or sinew) is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension.
Tendons are similar to ligaments and fasciae; all three are made of collagen.
Ligaments join one bone to another bone; fasciae connect muscles to other muscles.
Tendons and muscles work together to move bones.
The tendon is the part of the muscle that connects directly to the bone.
Answer:
C .25 grams
Explanation:
After each half life, the mass is reduced by half.
2/2 = 1
1/2 = 0.5
0.5/2 = 0.25
Answer:
1428.6m/s²
Explanation:
Given parameters:
Force applied on the body = 40N
Mass of the body = 28g
1000g = 1kg
28g will therefore be 0.028kg
Unknown:
Acceleration = ?
Solution:
To solve this problem, we use the expression derived from Newton's second law of motion.
Force = mass x acceleration
Insert the parameters and solve;
40 = 0.028 x acceleration
Acceleration = 
= 1428.6m/s²
