We know that
Speed of light = wavelength X frequency
Energy of light = h X frequency
Where
h = planck's constant = 6.626 x 10–34 j·s
frequency = speed of light / wavelength = 2.998 x 10^8 m/s / 656.3 X 10^-9
frequency = 4.57 X 10^14 / s
Energy = 6.626 x 10–34 j·s X 4.57 X 10^14 / s = 3.028 X 10^-19 Joules
Answer:
B, increases rate of collisions
Explanation:
Answer:
I'm not sure which bond stores the most energy but the ionic bond is stronger than the covalent bond.
Explanation:
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96).
Explanation:
Given that,
Mass of a car, m = 1200 kg
Acceleration of the car, a = 35 m/s²
The force acting on the car is given by :
F = ma
F = 1200 kg × 35 m/s²
= 42000 N
If the force is 30,600 N, then acecleration is given by :
Hence, this is the required solution.
