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:
Explanation:
When the number of slits increases, the intensity of fringes increases.
So, the fringes appear to be more bright.
As we know that the fringe width is inversely proportional to the number of slits, so as the number of slits increases, the fringe width decreases, hence the fringes are narrower, bright and close together.
Answer:
A. 1254.4 J
B. 1254.4 J
C. 43904 calories
Explanation:
Parameters given:
Mass of barbell, m = 160 kg
Length of arm, d = 0.8
A. Work done by weight lifter in lifting the barbell is:
W = F * d
Where F is force
F = m * g
=> W = m * g * d
W = 160 * 9.8 *0.8
W = 1254.4 J
B. Potential energy is given as:
PE = m * g * h
Where h is height (in this case, D)
=> PE = m * g * d
PE = 160 * 9.8 * 0.8
PE = 1254.4 J
C. The number of calories the weight lifter uses after lifting the barbell 35 times is equal to 35 times the potential energy, since a calorie is the measure of the amount of potential energy a piece of food contains:
35 * 1254.4 = 43904 calories.
Answer:
The removal of heat energy slows the speed of particles
Explanation:
When you add heat to a substance, the heat energy gets transferred to kinetic energy, and the molecules began to move a greater distance at a greater speed. When you remove heat, the opposite happens.
