Answer:
No element gains 4 electron in the case of transition element they bonds with covelent bonding whereby the electrons are shared around the last orbits
Explanation:
Answer:
Explanation:
easy way
when system is all kinetic energy, velocity is at a maximum
E = ½mv²
v = √(2E/m) = √(2(25)/0.5) = √100 = 10 m/s
harder way
ω = √(k/m) = √(80/0.5) = √160 rad/s
When the system is entirely spring potential, the amplitude A is
E = ½kA²
A = √(2E/k) = √(2(25)/80) = 0.790569... = 0.79 m
maximum velocity is ωΑ = 0.79√160 = 10 m/s
Answer:
Base units are defined units based on specific objects or events in the physical world. Derived units are defined by combining base units.
Base units are defined by a particular process of measuring a base quantity whereas derived units are defined as algebraic combinations of base units. For example, length is a base quantity in both SI and the English system, but the meter is a base unit in the SI system only.
Answers:
1) Time it takes to travel to the moon
Velocity
is defined as:

Where:
is the average distance from Earth to the Moon
is the velocity of the spacecraft
the time
Isolating
:


This is the time in hours
2) Time in days
A day is equivalent to 24 hours:

Hence:

This is the time in days
3) Time in months
A month is equivalent to 30.4 days:

Hence:

This is the time in months
