Consider a 200 g sample of u-238 with decay constant 2.951x10^-16 min^1. approximately how many disintegrations will occur per minute?

The disintegrations is .

Explanation:

Given that,

Weight of sample = 200 g

Decay constant

We need to calculate the disintegrations

Using formula of disintegrations

Where, = decay constant

N = number of atoms present at time t

Put the value into the formula

Hence, The disintegrations is .

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
