Answer:
The resistance is decreasing at a rate of 0.36 ohms/minute.
Step-by-step explanation:
The mathematical form of the Ohm's law is given by :
V = IR ...(1)
Where V is voltage, I is current and R is resistance
Given,
I = 5 A
R = 6 ohms
dI/dt = 0.3 A/min
Differentiate equation (1) wrt t:
When V is constant, dV/dt = 0
So, the resistance is decreasing at a rate of 0.36 ohms/minute.
Ruby's total earning for the month will be $4,020.
It is given that -
Ruby's monthly salary =$1,800
Ruby's commission on sales= 6%
Ruby's last month sales= $37000
<h3>What will be the total earnings of Ruby ?</h3>Ruby's monthly salary =$1,800
Ruby's commission on sales= 6%
Ruby's last month sales= $37000
Amount Ruby earned as a commission = = $2220
Ruby's total earning will be = Salary + commission
= 1800+2220
= $4020
Hence Ruby's total earning for the month will be $4,020.
