Answer:

Yellow light is a combination of red and green light. So combining blue with yellow light is like combining blue light with red and green light. The result of combining these three primary colors of light is to produce white light.

A solid uniform sphere of mass 5 kg and radius 0.1 m rolls down an inclined plane without slipping. if the sphere's center of ma

ANTONII [103]

Since sphere is performing pure rolling motion

So here the contact point of sphere with respect to inclined plane is always at rest.

This contact point will not move at any instant and and hence sphere will perform pure rolling.

So here we can say that sphere will have some friction force at the contact point but there is no displacement of that point.

So the work done by this static friction will always ZERO.

$W_{friction} = F.d$

$W_{friction} = 0$

So there is no work done by friction on the sphere while it is in pure rolling.

A parallel circuit is constructed with three different branches. An ammeter is placed in each of the branches to measure the bra

neonofarm [45]

Answer:

Current in the battery will be 11.7 A

Explanation:

We have given that the there is parallel circuit with three different branches.

Current in each branch is $I_1=2.8A$ , $I_2=4.1A$ , $I_2=4.8A$

We have to find the current I in the battery

It is known that in parallel circuit current is sum of current in each branches

So current in the battery will be equal to

$I=I_1+I_2+I_3$

$I=2.8+4.1+4.8=11.7A$

Therefore current in the battery will be 11.7 A

When does a scientist create the conclusion?

Gre4nikov [31]

The best answer is d - while comparing the data with the hypothesis. The scientific method defines the correct steps as:

1. observation - use of the five senses to learn about something.

2. Question - where you raise questions based on your observation.

3. Hypothesis - a prediction or guess of what the answer to the question is.

4. Method - point where you test the hypothesis by carrying out an experiment.

5. Results / data - this is what happened after each step of the experiment.

6. Conclusion - where the results of the experiment are discussed and it is summarized if the prediction was true or not, based on data from the results.
