Answer:
923.44N
Explanation:
Obviously Fn cannot equal Fg since the elevator is moving up
Where Fn is the force read on the scale
Fg is gravitational force=mg=77.6 x 9.8=760.48N
So we use this equation:
Fnet = Fn - Fg
ma = Fn - mg
77.6 x 2.1 = Fn – 760.48
162.96N = Fn – 760.48N
923.44 N = Fn
The answer is 923.44 N
Oil leakage in aquatic areas. (fish)
Burning fuel. (Air/global warming)
Toxic waste burried in dirt (living Creatures)
Lights/Electricity (destroyes Birds migration)
Noise (migration on dolphines and other sea mammals)
The answer is metabolic heat.
<span>Organisms from the higher trophic levels consume organisms from the lower trophic level and during that process, energy is lost as metabolic heat. Primary producers (plants) contain the greatest amount of energy originally from the sunlight. The next trophic level belongs to primary consumers that consume primary producers. During consumption, energy is lost. Similarly, secondary consumers eat primary consumers and energy is lost again. The highest trophic level is tertiary consumers that contains the least amount of energy.</span>
Answer:
d = 13.7 m
Explanation:
When block is moving upwards along the inclined plane
then the block is decelerated due to gravity as well as due to friction and speed of the block by which it is projected upwards is given
deceleration caused to the block due to net force opposite to the motion is given as
since block is sliding on the inclined plane
so here we can say that the coefficient of the friction must be kinetic friction here
now for finding the distance upto which it will stop is given as
