The angular velocity, ω=
2π/t; t = 24 hrs = 24 x 3600 seconds = 86400 s
ω = 7.27 x 10⁻⁵
v = ωr
= 7.27 x 10⁻⁵ x 3242.8 x 1.6 x 1000 (converting miles to meters)
= 377.2 m/s
Because it doesn't use energy it uses mechanical and kinetic
The change in speed of this object is 3m/s
According to Newton's second law;
F = ma
F = mv/t
Given the following parameters
Force F = 8.0N
mass m = 16kg
time t = 4.0s
Required
speed v
Substitute the given parameters into the formula
v = Ft/m
v = 8 * 6/16
v = 48/16
v = 3m/s
Hence the change in speed of this object is 3m/s

The answer is:
It is a measure of the strength of the bonds between ions.
Lattice energy is an estimate of the strength of the bonds formed by ionic compounds.
The first two choices are wrong because it is actually the opposite.
- As the ion size increases, lattice energy <u>decreases</u>.
- As charge of ions increases, lattice energy <u>increases</u>
As for the other third option, it is wrong because lattice energy is the energy RELEASED not absorbed.
Answer:
hope this helps
Explanation:
The elements in the modern periodic table are arranged in order of their atomic numbers, which is the number of protons in the nuclei of the atoms of a an element. Each element has a unique atomic number. The atomic numbers are also whole numbers.
