Answer:
A 1.0 min
Explanation:
The half-life of a radioisotope is defined as the time it takes for the mass of the isotope to halve compared to the initial value.
From the graph in the problem, we see that the initial mass of the isotope at time t=0 is
The half-life of the isotope is the time it takes for half the mass of the sample to decay, so it is the time t at which the mass will be halved:
We see that this occurs at t = 1.0 min, so the half-life of the isotope is exactly 1.0 min.
Most often those smaller structures are triangular in shape because triangular shapes are very strong and stable
<span>The flight controls must be held with left aileron up and elevator neutral while taxiing a tricycle-gear equipped airplane with a left quartering tailwind. In aircraft, ailerons are placed on the trailing edge of each wing near the wingtips and can be moved up and down. So when the left aileron is up, the movement of the airplane moves to the left and turns the wheel in a counterclockwise direction while at the same time, the right aileron is down.

Answer:
Force on the singly charged ion will be 
Explanation:
We have given electric field E = 8 MN/C
So electric field in N/C will be 
It is given that ion so charge on ion will be equal to 
We have to find the electric force on the ion
Electric force is equal to 
, here q is charge and E is electric field
So force on the charge will be equal to 
So force on the singly charged ion will be
