The answer is d.heuristic
D) 25N!
Under the term we have work (100J) and movement of the subject (4m).
You should find force:
A=F*s
F=A/s
F=100/4
F=25 N
To solve this problem it is necessary to apply the concepts related to density, such as the relationship between density and Volume.
The volume of a sphere can be expressed as
Here r is the radius of the sphere and V is the volume of Sphere
Using the expression of the density we know that
The density is given as
Now replacing the mass given and the actual density we have that the volume is
The radius then is,
Replacing,
The radius of a sphere made of this material that has a critical mass is 9.02 cm.
Answer:
In physics, if there is biggest mass then the slow down time is more and this effect is basically known as gravitation time dilation. This type of effect can easily be calculated from the different type of metric in the environment.
When some outsider observe then, this effect time seemed to be slowed down. It basically measure the overall amount of the time which elapse at observer distance. Therefore, this is the main concept of the mass slow down time.
