Answer:
The average current I supplied to the cars motor is 0.225 Amperes.
Explanation:
The mass of the toy car is given as, m = 0.6 kg
The toy car operates at a steady speed of, v = 3.43 m/s.
It achieves the steady speed after a time, t = 5.69 seconds.
The total kinetic energy of the car is given by,
E = 
= 0.5 × 0.6 × 
= 3.53 Joules
Since the efficiency of the motor is 30.6% = 0.306
The electrical energy equivalent is supplied to motor = 
.
The electrical energy is given by P × t = I × V × t = 11.54 Joules
P is the electric power where P = I × V where V is the voltage of the cell and is the average current, I.
Therefore we can write I × 9 × 5.69 = 11.54 Joules.
So the average current I = 
= 0.225 Amperes.
Answer:
The code is written in python in the explanation section below
Explanation:
a_feet = int(input("Input the feet of the first fabric: "))
a_inches = int(input("input the size in inches for the first piece of fabric: "))
b_feet = int(input("input the size in Feet for the second piece of fabric: "))
b_inches = int(input("Enter the size in Inches for the second piece of fabric: "))
sum_inches = a_inches + b_inches
inches_to_feet = sum_inches // 12
rem_from_div = sum_inches % 12
sum_feet = a_feet + b_feet + inches_to_feet
print("Feet: {} Inches: {}".format(sum_feet, rem_from_div))
Light / Radiation. The light radiation defines its color. Thermal radiation for its temperature and the overall appearance of the wavelengths the star emits gives off the info from where astronomers and scientist are able to build up knowledge on the age and current state of the stars
D. Heat energy will be transferred within the system and if left long enough, there will be enough transferred energy to make both of them the same temperature.
