Newton's first law of motion predicts the action of objects for which all existing forces are balanced. The first law, also referred to as the law of inertia, states that if the forces acting upon an object are balanced, the acceleration of that object will be 0 m/s/s. Objects at equilibrium will not accelerate. According to the law, an object will only accelerate if there is an unbalanced force acting upon it. The presence of an unbalanced force will change its speed, its direction, or both its speed and direction. All forces retaining to this law are related to inbalance
Answer:
A. Equal to and Opposite
Explanation:
when there is no External force acting on the system of bodies then Net momentum of the system is Conserved .
Given that there are 2 bodies
Let P₁ as first object's momentum
P₂ as second object's momentum.
Total Momentum =P₁ + P₂
As there is no external force acying on the system
Change in the Total momentum is zero
so,
0 = Δ P₁ + ΔP₂
ΔP₂ = -ΔP₁
negative sign indicates opposite direction.
Both are of equal magnitude.
Answer: cost to implement conservation policies
environmental implications
benefit versus the cost
Explanation:
The conservation policies involves certain instructions which are required to be followed by the human society at all levels so as to conserve resources and protect them for future. The following are the issues which government should be consider before passing the conservation policies this includes:
1. cost to implement conservation policies
: The procedure and expenditure for the implementation of the policies should be under control of the desired budget so that the plan can be efficiently executed.
2.environmental implications
: The government should be concerned about the implication of the policies on the environment. For example the preservation of an endangered species in control condition from an ecosystem can disturb the overall balance of an ecosystem.
3.benefit versus the cost: The government should concern before expending on the implementation of the policies the benefits and costs of the desired policies.
I think it's C, longer wave length.
Answer:
fossil fuels are being used more because fossil fuels are of great importance because they can burn to produce a significant amount of energy per unit mass the use of coal as a fuel prefates recorded history.
