Which is a true statement about a zero net force?
A zero net force causes a change to an object’s direction.
B.zero net force causes a change to an object’s speed.
C.A zero net force causes a change to an object’s acceleration.
D.A zero net force causes no change in an objects motion.
Answer:
D)a zero net force causes no change in an objects motion.
A zero net force causes no change in an object's motion. This statement is true about zero net force. Therefore, option D is correct.
What is zero net force ?An item that is originally at rest and has no net forces operating on it will stay at rest. If it is going, it will keep moving straight forward at a consistent speed. Forces are "pushes" or "pulls" on the object, and they are vector numbers, just like acceleration and velocity.
A automobile travelling at 50 mph on a highway continually has a net force of zero even though it is moving, since there is no acceleration and the speed is constant.
The total net force acting on an object as it moves at a steady speed is always zero. If you apply force, friction or another force (or several forces) will balance it out.
Thus, option D is correct.

Where are hormones produced in animals, and how are they transported throughout the body?
A. Animal hormones are produced in endocrine glands and travel through the blood.
B. Animal hormones are produced in lymph nodes and travel through the lymphatic system.
C. Animal hormones are produced inside the bones and travel through the nervous system.
D. Animal hormones are produced in sweat glands and travel through the skin.
Answer:
Vertebrate Endocrine Glands and Hormones
Unlike plant hormones, animal hormones are often (though not always) produced in specialized hormone-synthesizing glands (shown below). The hormones are then secreted from the glands into the blood stream, where they are transported throughout the body.

The dimensions of a cuboid are in the ratio of 1:2:3 and its total surface area is
88m square. Find
the dimensions.
Answer:
The length of the cuboid =x=2m, breadth =2x=4m, height =3x=6m
Explanation:
Let the length of the cuboid =x, breadth =2x, height =3x
Total surface area of a cuboid =2(l×b+b×h+l×h)
Given, total surface area of the cuboid =88m^2
2( x*2x + 2x*3x + x*3x )=88m
22x^2 =88
x=2
Hence, the length of the cuboid =x=2m, breadth =2x=4m, height =3x=6m

[Ne] 3s^ 2 3p^ 4 can someone tell me the element
Answer:
Sulpher
Explanation:
For this type of questions; calculate the total number of electrons so that you can identify the element from the periodic table.
Neon has 10 electrons. and from 3s^2 and 3p^4 there are 6 electrons.
So the total number of electrons is 16.
The element is Sulpher from group 6 of the periodic table

3.Zinc has an atomic number of 30 and a mass number of 65, how many neutrons does it have?
30
65
35
95
Answer:
35
Explanation:
Given parameters:
Atomic number of zinc = 30
Mass number of zinc = 65
Unknown
Number of neutrons = ?
Solution:
The mass number of an atom is the sum of its protons and neutrons;
Mass number = Protons + neutrons
Atomic number is the number of protons in an atom;
Atomic number = Protons
So;
Mass number = Atomic number + Neutrons
Neutrons = Mass number - Atomic number
Neutrons = 65 - 30 = 35
The number of neutrons in the atom is 35
