Answer:
250 N
433 N
Explanation:
N = Normal force by the surface of the inclined plane
W = Weight of the block = 500 N
f = static frictional force acting on the block
Parallel to incline, force equation is given as
f = W Sin30
f = (500) Sin30
f = 250 N
Perpendicular to incline force equation is given
N = W Cos30
N = (500) Cos30
N = 433 N

A. A higher fertility rate
B. Less access to medicine
C. A new source of fresh water
D. A higher birthrate
The answer is; C
Carrying capacity is the maximum population size than habitat or environment can sustain indefinitely because it is able to replenish its resources. Limiting factors to carrying capacity of an ecosystem include resources such as food, water, and space.
Density means how much mass is concentrated in the given 3d space .thus the more the density the more mass is occupied in the less space.. and thus the objects with lesser density floats on the object with higher density
