Answer:
3. a leaf falling off of a tree to the ground.
Explanation:
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
- F represents force measured in Newton.
- m represents the mass of an object measured in kilograms.
- a represents acceleration measured in meters per seconds square.
Force can be categorized into two (2) main types; forces that at a distance and forces the act by direct contact with the body.
A force that acts at a distance refers to the force exerted on a body or an object without any physical contact between them such as gravitational force, magnetic force and electric force. This simply means that, there can be a push or pull between objects even when they are not in physical contact with each other due to gravitational, magnetic or electric forces.
<em>Some example of a force that acts at a distance is a leaf falling off of a tree to the ground, a magnet pulling an object to itself, a magnet pushing or repelling another magnet etc. </em>
Answer:
25% red flowered
25% white flowered
50% pink flowered
Explanation:
Let the red flower color be represented by RR, the white color by rr.
When RR was crossed with rr, the offspring had pink flowers;
RR x rr = Rr, Rr, Rr, Rr (Pink color)
Crossing Rr with another Rr
Rr x Rr = RR, Rr, Rr, rr
RR = red
Rr = pink
rr = white
<em>Hence, if a pink flowered plant is crossed with another pink flowered plant, 25% of their offspring will be red, 25% will be white and 50% will be pink.</em>
<u>Answer</u>:
D. Models are not the "real thing" so it will never correctly represent the system in all respects.
This is the limitation of a scientific model
<u>Explanation</u>:
Scientific models are simplified than the real concept. It is not substitute for those scientific experiment which is continuously generating data. In scientific model lots of problem occur. In most of the scientific model we find details are missing. Models are based on approximation. It doesn’t give proper information about that topic. Scientific model has less accuracy. In process of making simpler, these models lost the accuracy. It cannot represent all the detail which eventually creates lots of problem in understanding the topic
