Several information's that are required to get to the answer of the question is already given in the question. It is important to write them down first and then start solving the problem.
Force = 400 newton
Mass = 100 kg
We already know that
Force = Mass * Acceleration
Then
Acceleration = Force/Mass
= 400/100
= 4 m / S^2
The acceleration of the object is 4 m/s$2. I hope the procedure is clear for your understanding. In future you can use this method for solving such questions.
Carcinoma refers to a malignant neoplasm of epithelial origin or cancer of the internal or external lining of the body. Carcinomas, malignancies of epithelial tissue, account for 80 to 90 percent of all cancer cases. Epithelial tissue is found throughout the body.
Answer:
Explanation:
a ) Current remains the same throughout the whole of a closed circuit if all the resistances are in series. So current will remain the same in both these conductors as they are in series.
b ) If the two wires are switched or exchanged mutually , there will not be any change in the current are they will still remain in series and total resistance remains the same . so current will remain the same . Hence the current through the bulb will remain unchanged . The brightness too will remain the same.
8. The answer is C
9. Sorry I don't know
