Explanation:
Answer:
The remains of producers are broken down by decomposers.
The remains of consumers are broken down by soil decomposers.
Animals break down food molecules to obtain energy.
Explanation:
When magnetic field lines and surface area are perpendicular to each other.
Answer:
Explanation:
F = GmM/d²
As gravity force is proportional to the inverse of the square of the distance,
doubling the distance will reduce the weight to a forth.
F' = GmM/(2d)²
F' = ¼GmM/d²
F' = ¼F = ¼(4000)
F' = 1000 N
Answer:
The compression is
.
Explanation:
A Hooke's law spring compressed has a potential energy

where k is the spring constant and
the distance to the equilibrium position.
A mass m moving at speed v has a kinetic energy
.
So, in the first part of the problem, the spring is compressed a distance d, and then launch the mass at velocity
. Knowing that the energy is constant.

If we want to double the kinetic energy, then, the knew kinetic energy for a obtained by compressing the spring a distance D, implies:

But, in the left side we can use the previous equation to obtain:





And this is the compression we are looking for
