Question

Write True if the statement is correct and False if the statement is incorrect

1. The precision is good if each of the measurements closer to true value.
2. Gamma rays are positively charged partides. 3. Most mass of an atom concentrated in the
nucleus of an atom.
4 Photon of high frequency radiation have high energies.
5 0.080 has three significant figures.​

Answer 1

1. The precision is good if each of the measurements closer to true value. True

2. False because Gamma rays are neutral

3. True. The nucleus of an atom contains the protons and neutrons, which are much more massive particles than the electrons found orbiting outside the nucleus. As a result, the mass of an atom is concentrated in the nucleus.

4.True. The higher the photon's frequency, the higher its energy. Equivalently, the longer the photon's wavelength, the lower its energy.

5.False.0.080 mm has 2 significant figures because the leading zeroes are not significant and the trailing zero after the decimal is significant

Hope this helps!
