You answer should be C sorry if I’m wrong
Answer:
- Here we use the conservation of momentum theorem.
- m stands for mass, and v stands for velocity. The numbers refer to the respective objects.
- m1v1 + m2v2 = m1vf1 + m2vf2
- Since the equation is perfectly inelastic, the final velocity of both masses is the same. Let’s account for this in our formula.
- m1v1 + m2v2 = vf(m1 + m2)
<u>Let’s substitute in our givens.</u>
(0.002 kg)(700 m/s) + (5 kg)(0 m/s) = vf(0.002 kg + 5 kg)
I assume you are proficient in algebra I, so I will not include the steps to simplify this equation.
Note that I have considered the bullet’s velocity to be in the positive direction,
The answer is vf = 0.280 m/s
A: Renewable resources make cleaner energy.
D: It often costs more to produce energy from renewable resources.
E: More local suppliers can provide energy from renewable resources to customers
Explanation:
Renewable sources of energy are cleaner and more accessible source of energy. They are easily replenished.
With current usage metrics, they can satisfactorily meet the energy demand of the world without affecting their supply.
- Renewable energy include biomass, wind energy, wave energy, solar energy e.t.c
- These energy sources are easily replenished.
- To produce energy from renewable sources, it usually costs more.
- Most equipment and devices that produces energy from renewable sources are highly pricey.
- Renewable energy is the future of energy production.
- Most smart cities around the world have solely relied on harnessing this source of energy.
- They no carbon emission to the environment and would not lead to climate change.

A circle graph, or a pie chart is used to visualize information and data. A circle graph is used to easily show the results of an investigation in proportional manner. The arcs of a circle graph are prepositional to how many percent of population gave a certain answer
Answer:
Explanation:
Using the law of the convervation of energy E:
so:
where is the constant of the spring 1, the compressed of the first spring, is the constant of the second spring and is the compressed of the second spring.
Replacing values, we get:
Solving for :
