Answer:
The induced current is 
Explanation:
From the question we are told that
The number of turns is 
The cross-sectional area is 
The initial magnetic field is 
The magnetic field at time = 1.02 s is 
The resistance is 
The induced emf is mathematically represented as
The negative sign tells us that the induced emf is moving opposite to the change in magnetic flux
Here 
is the change in magnetic flux which is mathematically represented as
Where dB is the change in magnetic field which is mathematically represented as
substituting values
Thus
So
The induced current i mathematically represented as
substituting values
Answer:increasing any of them, either mass or speed by 1unit will cause an increase in energy,
Explanation:
By increasing any of them, either mass or speed will cause an increase in energy.
Because kinetic energy is proportional to mass and also directly proportional to velocity
We use the radioactive decay equation for this problem which is expressed as:
An = Aoe^-kt
An is the remaining amount after time t, Ao is the initial amount and k is a constant.
First, we determine the k from the half life as follows:
An/Ao = 1/2 = e^-k(14.4)
k = 0.04814
Then, we can calculate An after 28.8 yr.
An = 1000 e^-0.04814(28.8)
An = 250 g
At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of the gas. PV =n RT, where R is the universal gas constant. A change in pressure depends with the number of moles of the gas, such that if the number of moles increases then there are many vibrations and collision of the gas molecules with the walls of a container thus increasing the pressure and vice versa.
20 g / 5 cm^3 = 4 g/cm^3 or 4000 kg / m^3.
