Answer:
1 mole of every substance has 6.022 × 10^23 particles. This is called Avagadro's constant
Answer:
T = 17649.03 N = 17.65 KN
Explanation:
The tension in the cable must be equal to the apparent weight of the passenger. For upward acceleration:

where,
T = Tension in cable = ?
= Apparent weight
m = mass = 1603 kg
g = acceleration due to gravity = 9.81 m/s²
a = acceleration of elevator = 1.2 m/s²
Therefore,

<u>T = 17649.03 N = 17.65 KN</u>
Answer:
2,8
Explanation:
The first electron shell would have 2 electrons, the second shell would have 8 electrons. This is because Neon has a relative charge of 10.
By calculating the crests, you can find the waves' frequency.
