Answer: PE = 800j, KE = 800J
Explanation:
To calculate the potential energy, we use the formula
Potential Energy = Mgh
M = 20kg, g = 10m/sˆ2 , h = 4m
=20 × 10 × 4
=800J
At the maximum height S = 4 and the initial velocity u = 0 The acceleration g = 10m/sˆ2
Using the third equation of motion
vˆ2 = uˆ2 + 2as
= 0ˆ2 + 2 × 10 × 4
vˆ2 = 80
Kinetic Energy (KE) is given by
KE = ½ mvˆ2
= ½ × 20 × 80
=800J
According to the chart, the marginal cost of producing the second pie is 0.50 so option 2) is the correct one.
Option 1) “1.00” is incorrect since that is the marginal cost of producing 1 pie
Option 3) “0.25” is also incorrect since that is the marginal cost of producing 3 pies
And finally, option 4) “1.25” is also incorrect since that is the marginal cost of producing 5 pies.
If the words "positive" and "negative" here refer to whether propaganda aims to create a positive or negative image, then the answer is :"True".
For example, in Socialist Countries in 1970s a big portion of propaganda was positive, aiming at convincing the citizens that socialism is good for the country. <span />
Explanation:
ha haha lol who is that now
"Blaxican" is a term for peoples who identify to be of both African and Mexican descent (Afro-Mexican).
These people trace their roots to both the continent of Africa and to the Latin country of Mexico. Often times these people originate on the West coast of the United States (especially to the states of California, Texas, Arkansas, etc.) where people of African origin and Mexican origin live in close proximity to one another and choose to culturally intermix.
