Answer:
this is based on your opinion but mine is...
Explanation:
Do you think that the role of culture, gender, and/or race has changed in sclence between the times we are learning about and today's times? If so, how? If not, explain your thoughts?
Yes by how because Race’ cannot be biologically defined due to genetic variation among human individuals and populations. (A) The old concept of the “five races:” African, Asian, European, Native American, and Oceanian. According to this view, variation between the races is large, and thus, the each race is a separate category. Additionally, individual races are thought to have a relatively uniform genetic identity. (B) Actual genetic variation in humans. Human populations do roughly cluster into geographical regions. However, variation between different regions is small, thus blurring the lines between populations. Furthermore, variation within a single region is large, and there is no uniform identity.
Answer:
OC The electric force between them decreases.
Explanation:
Electric force is a force due to charges which charged objects exert on each other. The charged objects A and B thus exert a definite force on each other which its value can be varied by varying the distance between them.
It is goo to note that the force between two charges is inversely proportional the the square of the distance between them. Thus when the distance is increased, the electric force would decease.
In the given question, option C is appropriate.
Answer:
mm/min
Explanation:
h = height of the water level above the hole = 1 m
= diameter of hole = 4 mm = 0.004 m
= Area of cross-section of hole = 
= diameter of tank = 2 m
= Area of cross-section of tank = 
R = rate at which the water level drop
Rate at which the water level drop is given as
m/s
mm/sec
mm/min
mm/min
Given: Force=8000N
displacement= 15 m
W=denotes Work
W= f × d
Substitute Values:
W = 8000 N × 15 m
= 120, 000 Nm
So, the elevator is doing 120, 000 Joule.
( Joule is the SI unit of work)
