Sidana [21]4 years ago
3 0

Answer:

biomass

Explanation:

The alternative source of energy for burning is biomass.

The non renewable source of energy is the source which can not be re obtained. It is limited in amount and after some time, we face energy crisis. Even when we burn such sources of energy, it causes pollution, smoke, etc.

Which of the following are characteristics of good experimental design? Check all that apply.
miv72 [106K]

Answer:

The correct answer will be-

1. Allows scientists to replicate experiments

2. Tests only one variable at a time

3. Plans how to record data so they can be published

Explanation:

A scientific experiment is performed to test the hypothesis which represents the limited explanation of the phenomenon.

The experiment is designed in a way that it test one variable at a time like the growth of plants. The experiment must be designed in a way that it can be replicated to reduce the error and repeated by other scientific persons to support the experiment. The design includes the plan for recording the results as it is one of the steps of the scientific method.

Thus, the selected options are the correct answer.

Controlled experiment is the type of experiment that involves changing only one variable at a time. Controlled experiment is subtly defined as an experiment which holds everything constant except one particular variable. This type of experiment allows only one variable to ever change at a given time

What can you assume has happened if an electron moves to a higher energy level
tresset_1 [31]

The extra energy that the electron suddenly has had to
come from somewhere, so I can assume that one of
two things happened:

either 1).  A photon passed by and the electron absorbed it.

      or 2).  Somebody hooked up a battery or a generator in
such a way that the electron was bathed in a field of electrostatic
potential, and suddenly had the get-up-and-go to jump to a higher
energy level, and possibly even to leave its atom completely and
zip over to a neighbor atom.

A train is moving with a velocity of 70 km/h.
hodyreva [135]

Answer:

B: It is moving north.

Explanation:

We are told that a train is moving with a velocity of 70 km/h.

Now, we are also told that the positive direction is north.

This means that the train is moving in the northern direction.

We can't say if it is speeding up or not because we are not given the acceleration.

Thus, option B is correct
