Answer:
d) Both blocks experienced equivalent energy loss due to friction
Explanation:
As stated in the question, two tractors are pulling two identical stone blocks the same distance across similar surfacesAdditionally, block A moves at double the speed of block B when completing the race
This implies both blocks suffer from comparable friction loss
Moreover, we understand that
Energy loss from friction is 
Thus, the friction loss should be identical for both blocks
therefore, option d is the accurate choice 
The task requires calculating toys produced per hour.
To find this, we divide the total number of assembled toys by the number of hours worked.
It operates on a five-day schedule.
Each day consists of 8 working hours.
This means the weekly total is 8 × 5 = 40 hours.
Over the week, 400 toys were made.
Thus, toys put together each hour per individual
= total toys / total hours
= 400 / 40
= 10 toys each hour for every person.
The average toys assembled hourly per person is 10.
15.87% of blue whales consume over 5,850 pounds of fish. Step-by-step explanation: The mean intake is 5000 pounds with a standard deviation of 850 pounds. We need to calculate P(x > 5850). Utilizing the z-score, z = (x - mean) / standard deviation gives us z = (5850 - 5000) / 850 which simplifies to z = 1. Subsequently, we find P(z > 1) from the z-score table, resulting in P(z > 1) = 0.8413. To find the percentage, we subtract from 1, yielding 1 - 0.8413 = 0.1587 and multiplying this by 100 gives us 15.87%.
