2. Describe a situation in which unbalanced forces are acting on an object. What is the net force
on the object, and how does the net force change the motion of the object?
Answer:
The force is by putting the two same objects on both sides and the motion is the scale
The force is by putting the two same objects on both sides and the motion is the scale.
What do you mean by force?In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull.
The normal force acts in a direction normal to the surface interaction between objects. Friction is a force that opposes motion on surfaces. Other examples of non-fundamental forces include the elastic force, tension.
Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element.

In a block and tackle system each pulley that you add will all the force to be ____.
1. decreased
2. increased
Answer:decreased
Explanation:
Answer:
Decreased
Explanation:
When you add extra pulleys, the minimum force that is needed to be given off by the person pulling lowers. For example if you have one pulley and pull on it, you require more force to move the object than your friend with two pulleys. He requires half the force that you do to move the object.

Patients with a specific medical condition have been provided with a new device that helps them manage their condition. The patients will be required to participate in a survey regarding the usefulness of the device. How can the manufacturer be certain that no bias enters into the surveys? Group of answer choices
Answer:
by providing a toll-free number in case there are questions about the devices.
Explanation:
One of the best ways to make certain that this does not happen is by providing a toll-free number in case there are questions about the devices. Doing so makes sure that the customers are fully aware and understand the device and what it is doing. This prevents the customer from assimilating other benefits that they may experience which have nothing to do with the provided device into the survey and potentially contaminating the data with false feedback.

Answer:
First Blank: Taiga
Second Blank: Tropical Rain forest
Third Blank: Desert
Explanation:
Process of elimination
1) we're given 4 answer choices but only three blanks. A tropical dry forest is not a thing so we know that one can't be it.
2) To be honest, I didn't know the first one off the bat, so I moved to the second blank and could easily tell it was the rain forest
3) The last blank was also obvious, being that desert climates are quite well known
4) So that left me with Taiga which I used for the first blank

If the Universe was born at the Big Bang, what existed before then
Explanation:
In the beginning, there was an infinitely dense, tiny ball of matter. Then, it all went bang, giving rise to the atoms, molecules, stars and galaxies we see today.
Or at least, that's what we've been told by physicists for the past several decades.
But new theoretical physics research has recently revealed a possible window into the very early universe, showing that it may not be "very early" after all. Instead it may be just the latest iteration of a bang-bounce cycle that has been going on for … well, at least once, and possibly forever.
Of course, before physicists decide to toss out the Big Bang in favor of a bang-bounce cycle, these theoretical predictions will need to survive an onslaught of observation tests.
The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang and thought to have contained all the energy and spacetime of the Universe.
What is a buffer? Why is it useful to cells?
Buffer are defined as substances that maintain a constant range of pH by the addition of the base and acid. It is important for cells to maintain the osmotic pressure and pH in the cell environment.
What is the importance of a buffer?In biology, the buffer has been the substances that are organic in nature and are used for regulating and controlling the level of the acids and bases that alters the pH of the system. It plays a crucial role in cells.
It is important for the cell to have a buffer solution, like bicarbonate ions in the blood that maintains the pH and the concentration of the hydrogen and hydroxide ions. It provides regulation of the osmotic balance and maintains the internal environment condition of the cell.
Therefore, the buffer is important for cells.

When offspring produced by sexual reproduction move into different environments, new species sometimes emerge over time. Which characteristic of sexual reproduction allows this result to occur?
A) speed with which offspring are produced
B) number of offspring produced
C) diversity of the offspring produced
D) size of the offspring produced
Answer:
c) diversity of the offspring produced.
Explanation:
Because sexual reproduction involves gametes (sex cells with only half the number of chromosomes), each offspring produced is genetically unique (as they get a random selection of chromosomes from both parents). This allows mutations to occur, which may be beneficial (or not) in the environment. Over time, the offspring that have the favourable characteristics will survive more easily to reproduce, whereas those with less helpful characteristics will not. This means that the favourable characteristics will be passed on to the next generation, while the less favourable ones will not be time. If this occurs for many generations, a new species may emerge.
