The correct answer is (a.) decomposition. The equation NaCl --> Na + Cl is a decomposition reaction. That is because the synthesis reaction looks like this Na + Cl = NaCl, and is the opposite of the decomposition. The decomposition reaction is the chemical reaction in which a single compound break into new compounds.
The image of the black body curve is missing, so i have attached it.
Answer:
T ≈ 3372 K
Explanation:
From the attached curve of the black star, if we trace the peak value of the wavelength from the graph, we will see that it is approximately 859.5 nm.
Thus; λ_peak = 859.5 × 10^(-9) m
From wiens law, we know that;
T•λ_peak = 2.898 × 10^(-3) m.K
Where T is surface temperature.
Plugging in the relevant values, we can find the temperature T
Thus;
T = (2.898 × 10^(-3))/(859.5 × 10^(-9))
T ≈ 3372 K
Answer : 413.44N
Here it is given that an elevator is moving down with an acceleration of 3.36 m/s² . And we are interested in finding out the apparent weight of a 64.2 kg man . For the diagram refer to the attachment .
- From the elevator's frame ( non inertial frame of reference) , we would have to think of a pseudo force.
- The direction of this force is opposite to the direction of acceleration the frame and its magnitude is equal to the product of mass of the concerned body with the acceleration of the frame .
- When a elevator accelerates down , the weight recorded is less than the actual weight .
From the Free body diagram ,
- Mass of the man = 64.2 kg
