Which change will always result in an increase in the gravitational force between 2 objects

2 answers:

8 0

Increase object mass or decrease the distance in between objects. Of the two, force is proportional to mass - double the mass, double the force. Distance is to the square - reduce distance to half, force will increase by 4x.

<span>Reducing the distance between them. In theory, also increasing the mass; but you can't really change the mass of an object. However, you can compare the forces if you replace an object by a different object, which has a different mass.

i hope this will work..

Answer:

the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.

Position coordinate of a particle confined to

Gelneren [198K]

Answer:

a) 4 s

b) 36 m/s²

c) 54 m

Explanation:

s = 2t³ – 24t + 6

a) Find t when v = 72 m/s.

v = ds/dt

v = 6t² – 24

72 = 6t² – 24

6t² = 96

t = 4

b) Find a when v = 30 m/s.

a = dv/dt

a = 12t

When v = 30:

30 = 6t² – 24

6t² = 54

t = 3

a = 36

c) Find Δs between t = 1 and t = 4

Δs = (2(4)³ – 24(4) + 6) – (2(1)³ – 24(1) + 6)

Δs = 38 – (-16)

Δs = 54

For a moon orbiting its planet, rp is the shortest distance between the moon and its planet andra is the longest distance betwee

Natasha2012 [34]

Answer: D. 0.57

Explanation:

The formula to calculate the eccentricity $e$ of an ellipse is (assuming the moon's orbit in the shape of an ellipse):

$e=\frac{r_{a}-r_{p}}{r_{a}+r_{p}}$

Where:

$r_{a}$ is the apoapsis (the longest distance between the moon and its planet)

$r_{p}=0.27 r_{a}$ is the periapsis (the shortest distance between the moon and its planet)

Then:

$e=\frac{r_{a}-0.27 r_{a}}{r_{a}+0.27 r_{a}}$

$e=\frac{0.73 r_{a}}{1.27 r_{a}}$

$e=0.57$ This is the moon's orbital eccentricity

List the three components of effective communication and give an example of each

Marrrta [24]

Answer:

The three components of effective communication are:

Sending Communication
Receiving Communication
Feedback

Explanation:

<h3>1) Sending Communication</h3>

One should think about what he is going to say, structure his message and focus clearly on a the purpose of sending a message. For example if an employer wants to communicate an employee to improve his performance, he should focus hid communication on the results rather than on his failures.

<h3 /><h3>2) Receiving Communication</h3>

The person on the other end of the communication should be a good listener. For example in the example given, even if the employer effectively communicates his side of the communication, but the employee is not paying his full attention to what his boss is saying, he wouldn't be able to make much of a difference.

<h3>3) Feedback</h3>

After sending and receiving communication, feedback should be given to complete the communication effectively. For example the employer may tell his boss about what he understood from his boss's speech, or what will he do to improve his performance.

kvasek [131]

They should see if there are any sources of bias

Explanation:

The best way to ascertain the reliability of the claim in the article is to see if there is a source of bias.

A source of bias in the article can tell a lot about how reliable and trustworthy the article is. It will also give room to more research about the claim in the article from other sources.

It is possible for some elements of bias to be introduced into a set of observation due to preference and choices.
