- Question #83e8c - Socratic
The unit for mass is the kilogram The unit for weight or force is the newton The kilogram is an indirect measure of the amount of matter that an object contains The mass in kilograms of an object is the same here on earth as it is in outer space The newton is a measure of force or weight The newton is based on the acceleration of gravity on earth The acceleration of gravity is 9 8 m s^2 l
- Question #3d631 - Socratic
A projectile is an object given an initial velocity on such a path that gravity continues modifying its path To have it hit a particular target, the effect of gravity on its path must be considered in order to hit the target
- Question #198f0 - Socratic
The experiment uses a combination of terminal velocity of charged oil drops under gravity alone, and when an electric field opposes gravity The following link provides one of the best explanations of the experiment, methology and data analysis I have found: PHYS 3324 Lab Millikan Oil Drop Experiment: Demonstration of the Quantization of Charge To answer a couple of specific concerns from your
- Question #6932a - Socratic
Zero Gravity is the attraction of one body to another body A body at the center of the Earth is surrounded by the mass of the Earth For every pebble of mass m a distance of s in one direction, there is a pebble of mass m a distance of s in the exact opposite direction The attractions of the body at the center of the Earth toward those 2 pebbles cancel each other out That is repeated all
- Question #0f823 - Socratic
Inside, there are a billions of collisions between hydrogen and helium atoms Like all stars, there is a shell encapsulating the series of atoms behind it The atoms are hydrogen, helium, carbon, and oxygen A Red Giant star is formed when it runs out of hydrogen fuel All of the once-existing hydrogen turns to helium, gravity causes the star to constrict and pull in on itself The star
- How does a star form? - Socratic
This will cause more mass to be attracted due to gravity after a long period the pressure and temperature at the core will be very high When the temperature reaches about 15 million atn the core nuclear fusion will start and star began to shine In the core 4 hydrogen atoms will fuse togather and form 1 helium atom and about 0 7% mass will be converted into energy picture credit science how
- Question #9be26 - Socratic
0 42"m" "specific gravity of wood" -> (700"kgm" m^3) (1000"kgm" m^3) = 0 7 ("no units!") % "of wood immersed" = 0 7*100 = 70% "volume of cube" = (0 6m)^3 = 0 216m^3 "depth of wood immersed" = 70%*0 215 = 0 1512m^3 Two of its sides will remain the same while immersed
- Question #9ed66 - Socratic
Given wt of the object in air = 320N wt of the object in water = 255N wt of the object in oil = 295N We know the density of water = dw = 1000kgm−3 acceleration due to gravity g = 9 8ms−2 Wt of displaced water by the object = Its wt in air −wt in water = 320 − 255 = 65N So mass of displaced water mw = 65 9 8kg = 6 63kg Volume of displaced water or volume of the object v = mw dw = 6 63
