Answer:
Friction = 5.027 N
Explanation:
Kinetic friction does not change with speed or acceleration. The only thing that is required is to state that the object is moving.
Solving the force equation for friction we get:
Friction = coefficient of friction* normal force exerted by the object
Friction = u * R
here R is = 0.84 * Gravity = 0.84 * 9.81 = 8.2404 N
u = 0.61 (as stated in the question)
So frictional force will be:
Friction = 0.61 * 8.2404
Friction = 5.027 N
Microplastics contain harmful chemicals that can accumulate in the food chain. The other chemicals released into the water when the plastic breaks down also has a negative impact on the sealife around. And with humans consuming contaminated fish and seafood, plastic pollution is certainly a human health issue too. microplastics were providing a medium to facilitate the transport of other toxic compounds such as heavy metals and organic pollutants.
Answer:
-0. 75m/s^2
Explanation:
use formula of acceleration
Answer:
The image distance is 30 cm
image height = - 5 cm
Explanation:
The formula for calculating the image distance is expressed as
1/f = 1/u + 1/v
where
f is the focal length
u is the object distance
v is the image distance
From the information given,
u = 30
f = 15
By substituting these values into the formula,
1/15 = 1/30 + 1/v
1/v = 1/15 - 1/30 = (2 - 1)/30 = 1/30
Taking the reciprocal of both sides,
v = 30
The image distance is 30 cm
magnification = image height/object height = - v/u
Given that object height = 5 cm, then
image height/5 = - 30/30 = - 1
image height = - 5 * 1
image height = - 5 cm
Hello!
Possible answer could be Organisms
There are a lot of Organisms in the overall food chain.
Hope this helped!
