I assume the element has 5 valence electrons (not neutrons). The similar properties are shared between y and z since they have the same number of valence electrons. This is what is primarily responsible for chemical behavior.
Answer:
3.6 arcsec
Explanation:
angular diameter = diameter / distance
diameter is constant
so angular diameter ∝ 1 / distance
angular diameter = k / distance
For first case ,
18 = k / .5
for second case let angular diameter be D .
D = k / 2.5
dividing ,
D / 18 = .5 / 2.5 = 1 / 5
D = 18 / 5 = 3.6 arcsec
3.6 arcsec is the answer .
Given that,
mass m= 5.7 kg
Force of gravity = ?
Since,
Force of gravity acting on earth is equal to the weight and
W= mg
W= 5.7 * 9.81
W= 55.917
or
W= 56 N
Force of gravity acting on Earth by the package is 56 N.
Answer:
The system prevents a consumer from accruing debt via electricity use, as it only allows the customer to use electricity which has been paid for upfront.
this gives the advantage of not allowing the consumer to rack up debt
the disadvantage for the consumer comes when they cannot afford to prepay in a time of financial difficulty - as the system now renders them as having no electricity as well as no money
The mass of the gas is169g.
