The refrigerator's power consumption is as follows:
If the refrigerator operates for 10 hours daily, the total monthly usage will be calculated as:
Consequently, the overall energy consumed in a month is expressed as:
It’s noted that the price of one kWh is $0.20, leading to the total cost for one month being:
The accurate answer is 36 miles per hour
Explanation:
To calculate the average speed, start by determining the total distance and total time Lucy traveled, as average speed is the total distance divided by the total time.
Total Distance
Lucy is known to have covered 2/3 of the total distance initially, later finishing the journey with 60 miles. Therefore, the last segment of 60 miles corresponds to 1/3 of the total distance.
(Total distance)
Consequently, since 60 miles equals one-third, multiplying this by 3 gives the total distance: 180 miles.
This indicates the total distance traversed is 180 miles
Total Time
Lucy took 3 hours for the first part of her journey and 2 hours for the second, leading to a total time of 5 hours (3 + 2 = 5)
Determining Average Speed
Result:
1.60 g
Elucidation:
Based on the attached document:
we can infer that:
The distance covered in 2 seconds will be:
x = vt
x = 20 m/s × 2 s
x = 40 m
The segment corresponds to a quarter of a circle with radius r,
therefore, if 2 πr = 4 x
Then the radius (r) can be calculated as:
r = 25.5 m
Centripetal acceleration can be expressed as:
thus;
a = 15.7 m/s²
The acceleration magnitude suffered by your passengers in relation to the acceleration due to gravity can be calculated using:
∴ The acceleration magnitude experienced by your passengers while turning = 1.60 g
