Answer:

q2 must also be doubled

r may also be halved

Explanation:

According to Coulumbs law

F= K q1 q2/r^2

If q1 is doubled, we must necessarily double q2 and r may also be halved in order to maintain F at the same value. Once the value of F is thus kept constant and E is also constant, the product FE must remain constant.

Which description matches up correctly with each type of particle? Alpha - no mass and no charge; beta - mass of 4 and charge of
Veseljchak [2.6K]
The closest answer is
Alpha - mass of 4 and charge of +2; beta - no mass and charge of -1; gamma - no mass and no charge (consists of energy)

It’s not exactly correct because a beta particle has the (small) mass of an electron (also the positron). All other choices are way off, I’d go with this one.

The innermost satellite of jupiter orbits the planet with a radius of 422 × 103 km and a period of 1.77 days. what is the mass o
FinnZ [79.3K]

The mass of Jupitar is obtained from the calculations as 5.8 * 10^-14 Kg.

<h3>What is the mass of Jupitar?</h3>

There are nine planets in the solar system and the sun lies at the enter of our solar system. This is the heliocentric model of the solar system.

Given that;

T^2 = GMr^3/4π

T = period

G = gravitational constant

r = radius

M = mass of Jupitar

Now;

1 day = 86400 seconds

1.77 days = 1.77 days *  86400 seconds/1 day

= 152928 seconds

Making M the subject of the formula;

M =4πT^2/Gr^3

M = 4 * 3.142 * (152928)^2/6.67 × 10^-11 * (422 × 10^9)^3

M = 2.9 * 10^11/5.0 * 10^24

M = 5.8 * 10^-14 Kg

How is an arranged marriage different from or similar to other ways people find and experience love today?
Zepler [3.9K]

Answer:

The arrange marriage and love marriage is same or different from each other "one is about loving and then getting committed and another one is getting committed and then loving,so in the either way both are same."

Explanation:

There is no difference at all! Because eventually, in both the cases, people manage to stay together and share the responsibilities. What actually matters is that, if Love happened.

Let’s put it this way. Two people fell in love and they get married, but why is that the same couple would want to separate later? Let’s take another example. Two people who don’t have any idea of each other’s existence get married. why is that they choose to live together forever? Love becomes the reason for any split or patch.

When two people are in love everything becomes easy. A relationship doesn’t look hard, in fact I have friends who have a wonderful married life and people still don’t bother to find if that’s a love or an arranged match. Few of them choose partners of their own and few of them fell head over heels in love with their spouse, but all of them look as if they are on an extended holiday.
