Answer:
D. recycling aluminum cans and glass bottles
Explanation:
it's the only one that makes sense because if its a short trip you should walk, you should use reusable bags, and turn off the water while brushing your teeth.
Hope this helps and have a wonderful day/night/afternoon
Hard.
Form crystal lattices not molecules.
Good insulators.
High melting points/ Boiling Points.
Conduct electricity when dissolved in water or as a liquid.
Solids do not conduct electricity.
Answer:
The speed of wavelength is 3.0 ×10³ m/s.
Explanation:
Given data:
De Broglie wavelength = 132 pm (132×10⁻¹² m)
Speed of wavelength = ?
Solution:
Formula:
λ = h/mv
λ = wavelength
h = planck's constant
m = mass of proton
v = speed
now we will put the values in formula.
132×10⁻¹² m = 6.63 ×10⁻³⁴ j.s / 1.67 ×10⁻²⁷ kg × v
v = 6.63 ×10⁻³⁴ j.s / 1.67 ×10⁻²⁷ kg × 132×10⁻¹² m
j = kg m²/s²
v = 6.63 ×10⁻³⁴ kg m²/s / 1.67 ×10⁻²⁷ kg × 132×10⁻¹² m
v = 6.63 ×10⁻³⁴ kg m²/s / 220.44 ×10⁻³⁹ kg.m
v = 0.03×10⁵ m/s
v = 3.0 ×10³ m/s
The speed of wavelength is 3.0 ×10³ m/s.
True
As the shorter the bond, the stronger it is hence more energy will be required to overcome this bond
