Answer:
Explanation:
The first diagram (by the left) is an endothermic reaction. In this reaction, the products are higher in energy than the reactants. Heat/Energy is absorbed in this reaction and enthalpy is positive. In second diagram (by the right) is an exothermic reaction. In this reaction, the reactants are higher in energy than the products. In this reaction, heat/energy is released.
Answer:
The answer is
The wavelength of the light is 557.2 x 10⁻⁻⁹nm
Explanation:
The wavelength of a wave is the distance between adjacent troughs and crests while the frequency of a wave is the number of completed cycles that pass a given per unit time
Electromagnetic radiation, such as light is usually described n terms of its frequency and wavelength
The equation relating the three quantities of speed of light, frequency and wavelength is as follows
Speed of light, c = Frequency of the light wave, ν × Wavelength of the light, λ
That is c = ν × λ
Where c = 299792458 m/s, v = 5.38 x 10¹⁴ Hz
Therefore the wavelength = = 5.572 x 10⁻⁷ m 557.2 x 10⁻⁻⁹nm
Answer:
19129.5 N
1.1831 m
Explanation:
m = Mass of person = 65 kg
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration = 30g
g = Acceleration due to gravity = 9.81 m/s²
Force is given by
The force on the person is 19129.5 N
The distance traveled if brought to rest is 1.1831 m
