The particle that was given off in the reaction beta rays is β–. Option C
<h3>What is a nuclear reaction?</h3>
A nuclear reaction will involve the change in the nucleus of an atom. It often leads to the production of new nucleus. As we can see the equation, there was a transformation from nitrogen nucleus to oxygen atom.
Thus, the particle that was given off in the reaction beta rays is β–. The fact that the mass number remained the same but the atomic number increased by one unit from left to right implies that a beta decay has occurred.

Answer:
Frequency = 260 Hz and wavelength = 1.31 m
Explanation:
Given that,
A hammer begins vibrating back and forth at approximately 260 cycles per second.
(a) The frequency of an object is the number of vibrations per unit time. The frequency of the sound wave is 260 Hz.
(b) The speed of sound in air is 343 m/s. So,
Hence, this is the required solution.
Answer:
Explanation:
Electric field strength, E = 5900 V/m
Magnetic field strength, B = 8.3 x 10^-3 T
The magnetic force on the charge particle is balanced by the magnetic force on the charge particle which is moving with velocity v.
qE = q v B
v = E / B
v = 7.1 x 10^5 m/s
