Answer:
T = 2390 degree C
Explanation:
Given data:
Resistance 12 ohm
Temperature 20 degree C

we know that linear relation between the resistance and temperature is given as![R = R_O[ 1+ \alpha ( T - T_o)]](https://tex.z-dn.net/?f=R%20%3D%20R_O%5B%201%2B%20%5Calpha%20%28%20T%20-%20T_o%29%5D)
where
is resistance at
and
= coefficient of resistivity

SOLVING FOR 
degree C
WE KNOW

T = 2370 + 20
T = 2390 degree C
Answer:
4 rolls
Explanation:
The probability of rolling a 6 is 1/6 = 0.1667 (4.d.p)
This means that approx. 1/6 of the dice will land on a 6.
If the student removes a 1/6 of the dice each time, it means that the number of dice is decreasing by 1/6 each roll (or multiplying by 5/6).
114/2 = 57
By multiplying 114 by 5/6 and continuing we can see how many times it takes for us to get past 57.
Roll 1: 114 x 5/6 = 95
Roll 2: 95 x 5/6 = 79.17
Roll 3: 79.17 x 5/6 = 65.97
Roll 4: 65.97 x 5/6 = 54.98
Most likely to take 4 rolls before halving the number of dice.
You could also solve this problems by writing an equation and solving using logs but I think this method is easier to understand.
Hope this helped!

The formular for determinatio of mass number is this:
Mass number = number of proton + number of neutron
From the question, we are told that:
Mass number = 39
Proton number = 19
Number of proton = ?
Number of neutron = mass number - number of proton
Number of neutron= 39 - 19 = 20
Therefore, number of neurtron = 20.
