There are a pair of forces ... two of them ... between you and the computer.
You're attracted to the computer, and the computer is attracted to you.
The forces have equal strength.
Force of gravity = (6.67 x 10⁻¹¹ N-m²/kg²) M₁· M₂ / (distance)²
= (6.67 x 10⁻¹¹ N-m²/kg²) (80 kg) (4 kg) / (0.25 m)²
= (6.67 x 10⁻¹¹ x 80 x 4 N-m²) / (0.125 m²)
= 1.71 x 10⁻⁷ Newton
= about 0.000 000 615 ounce .
THAT's why you don't feel especially attracted to your computer.
Answer: 29.50 m
Explanation: In order to calculate the higher accelation to stop a train without moving the crates inside the wagon which is traveling at constat speed we have to use the second Newton law so that:
f=μ*N the friction force is equal to coefficient of static friction multiply the normal force (m*g).
f=m.a=μ*N= m*a= μ*m*g= m*a
then
a=μ*g=0.32*9.8m/s^2= 3.14 m/s^2
With this value we can determine the short distance to stop the train
as follows:
x= vo*t- (a/2)* t^2
Vf=0= vo-a*t then t=vo/a
Finally; x=vo*vo/a-a/2*(vo/a)^2=vo^2/2a= (49*1000/3600)^2/(2*3.14)=29.50 m
Answer is 4,400,000 kg • m/s
Answer:
A separation technique to separate solids from a solution. Crystallization can be defined as the process through which the atoms/molecules of a substance arrange themselves in a well-defined three-dimensional lattice and consequently, minimize the overall energy of the system.
Explanation:
Chinook salmon work to maintain a stable internal environment despite changes in external conditions by the process called homeostasis. Homeostasis is important because salmon, like all living organisms, depend on the proper functioning of its cells to ensure its survival and the ability to reproduce.
