Halogens therefore react most vigorously with Group 1 and Group 2 metals of all main group elements.
Answer:
The current in the circuit must be zero.
Explanation:
In a RC circuit, the steady state is reached when either the capacitor is fully charged or fully discharged. In either case, there must not be any current through the circuit because if it exists, it will deliver charge to the capacitor and thus change its charge, which is not a steady state.
Answer:
The smallest diameter is
Explanation:
From the question we are told that
The resolution of the telescope is
The wavelength is
From the question we are told that
So
Therefore
Now
So
=>
The smallest diameter is mathematically represented as
substituting values
Answer:
The electron's speed is 34007.35 m/s
Explanation:
It is given that,
Magnetic field, B = 0.34 T
Magnetic force on the electron,
The electron follows a helical path. We have to find the speed of an electron. The formula for magnetic force is given by :
q = charge on an electron,
v = velocity of an electron
v = 34007.35 m/s
Hence, this is the required solution.
It will decay into Silicon-30. Because alpha particles are 2 protons and 2 neutrons with an atomic mass of 4, you minus sulfur's atomic number by 2 and get silicon. And the atomic mass is 34 - 4 which equals 30.
