Answer:
A. As the ropes are horizontal the child has travelled 2m of vertical displacement from his lowest position.
Gpe @ A=mgh=40*9.81*2=784.8J
B. At 30degree vertical angle the vertical displacement from lowest position is given by
2-2cos(30)=2-1.73=0.27m
Gpe @B= 40*9.81*0.27=106 J
C: at the bottom of circular arc it's Gpe is zero relative to lowest position as bottom of arc itself is lowest position.
Electrons are added to your body as you shuffle your feet across the room. Then the shock is when they discharge from your body to the doorknob when you touch it.
Answer:
0.7549kg
Explanation:
The mass of the slice + mass of the remaining cake = total mass of cake.
mass of remaining cake = total mass of cake - the mass of the slice
total mass=0.870kg
mass of slice = 0.1151kg
mass of remaining cake = 0.870 - 0.1151
mass of remaining cake=0.7549kg
The dog's length, width, height, mass, volume, density, and color are the same in both places.
Because the alpha particles were passing through the foil with slight to no reflection however some alpha particles were deflected with high angle or reversed direction which is not what was expected as according to thomson the atom is a lump of postively charged mass and there will be no deflection as the charge is distrbuted and the charge of alpha particle is 207 times that of electron
