Answer : The correct option is, (D) 273 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit
Explanation :
Conversion of degree Celsius to Kelvin :
Conversion of degree Celsius to degrees Fahrenheit :
By using these two conversion factors, we get the three temperature readings all mean the same thing.
For option A :
For option B :
For option C :
For option D :
From the given options, only option (D) is correct.
Hence, the correct option is, (D) 273 Kelvin, 0 degrees Celsius, 32 degrees Fahrenheit
It’s called the focus of the earthquake
The correct answer is A. While the Big Bang is very possible it is still a theory. Even if you accept it, you have to see its flaws. Nothing is without flaw. There are many things it doesn't account for. Now, again this is not to say it is untrue just flawed. The best argument against it or anything similar would be that no one seen it happen.
Given that,
Mass of a baseball, m = 0.2 kg
Initial speed of a baseball, u = 30 m/s
Force produced by a bat, F = 2000 N
Final speed of a baseball, v = -50 (negative for opposite direction)
To find,
For how long was the ball in contact with the bat?
Solution,
Let for t seconds the ball is in contact with the bat. The net force acting on the ball is given by :
So, the ball is contact with the bat for 8 ms.
Answer: A) 2 B) 4 C) 1
Explanation:
The Electric field from a parallel-plate capacitor is given by:
A) E=Q/(L^2 * ε0) so if we put a charge double the final electric field is double that the original.
B) from the above expression for the electric field, If the size of the plate is double, then the E final is four times weaker that the original.
C) If the distante between plates is doubled the final electric field is the same that initial.
