Answer:
The question is somehow not correct, it suppose to be what is the MASS of an object that needs a force 4500N to accelerate it at a rate of 5 m/s as gotten from another website.
The correct answer is 900kg.
Explanation:
To get the mass of the object use the formula
F=Ma
Where F is force
M is mass
a is acceleration.
F= 4500, M=? a=5m/s
4500= M× 5
M=4500/5
M=900kg
Mass is in kg
They tend to be bigger and stronger
The total number of protons plus neutrons is called the atomic mass number for the atom.
Answer:
D) Some kind of exoskeleton, or hard outer covering
Explanation:
Ecdysozoa is a clade of animals that gathers arthropods, nematodes and seven other phyla. These organisms have a type of exoskeleton, or hard outer lining that limits the growth of these animals. At some point in the life of these animals, the "exoskeleton" becomes tight and forces these animals to form a new exoskeleton in order to grow. The process of moving from one exoskeleton to another is called ecdysis and also happens in insects.
