Answer:
Explanation:
Magnitude of frictional force = μ mg
μ is either static or kinetic friction.
To start the crate moving , static friction is calculated .
a ) To start crate moving , force required = μ mg where μ is coefficient of static friction .
force required =.517 x 56.6 x 9.8 = 286.76 N .
b ) to slide the crate across the dock at a constant speed , force required
= μ mg where μ is coefficient of kinetic friction , where μ is kinetic friction
= .26 x 56.6 x 9.8 = 144.21 N .
The "generational change" approach to managing innovation assumes that innovation is a predictable process made up of a series of steps and that compressing the time ittakes to complete those steps can speed up innovation.
Answer:As a rule sound travels slowest through gases,faster through liquids,and fastest through solids.The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.Speed of light in water = 226 million m/s or 205,600 mph.
Explanation:dont have one
Answer:
F=2.47*10^{-10} N
Explanation:
The gravitational force is calculated by using
G: Cavendish constant = 6.67*10^{-12}Nm^2/kg^2
r=2.30cm=0.023m
M1=1.4kg
M2=14.0g=0.014kg
By replacing we have
F=2.47*10^{-10} N
hope this helps!!
