Answer:
This really depends on the graph but to approach these types of problems you can go about it this way (check explanation)...
Explanation:
(1) What is position?
Where is the object's location at?
If slope is zero, velocity is zero (straight line)
Slope positive, velocity is constant/ positive (linear line positive)
Object is accelerating.. curve upwards.
Steeper the slope, higher the speed
(2) What is velocity?
What are velocity vs. time graphs? - Khan Academy
Answer:
Option C
Explanation:
Answer C is the correct option. water can be written as H₂O, which means that there are 2 Hydrogen atoms for every oxygen atom, therefore it will occupy more space than oxygen and push more. there is also one more possibility, if the splitting takes place in Hoffman's Voltameter then the Hydrogen will be close to the cathode as hydrogen is positive. Otherwise, option C is correct answer. Hope this Helps you!
Answer:
i dont know i am right but here Luminous intensity is defined as dI=dΨλ / dΩ, where dΨλ is the luminous flux (light energy flux in watts per m2) emitted within a solid angle dΩ. The light energy flux may be expressed in terms of the incident x-ray energy flux and the x-ray absorption and conversion properties of the scintillator(7,8,9).
Explanation:
D
cause E=U and in power formula is p=U÷t or E÷t so E=p×t
