Answer:
The magnitude of the force is 1.29*10^-3N in the positive x direction
Explanation:
In order to calculate the magnitude and direction of the force, you take into account that the force is the space derivative of the potential enrgy, as follow:
(1)
where:
You replace the expression for U into the equation (1) and solve for F:
![F(x)=-\frac{d}{dx}[Ax^4]=-4Ax^3](https://tex.z-dn.net/?f=F%28x%29%3D-%5Cfrac%7Bd%7D%7Bdx%7D%5BAx%5E4%5D%3D-4Ax%5E3)
(2)
The force on the particle, for x = -0.080m is:
The magnitude of the force is 1.29*10^-3N in the positive x direction
Answer:
F = 0
Explanation:
Newton's second law is
F = ma
As in this case the two blocks move with constant speed, it implies that the acceleration is zero, therefore the force applied to the system is zero
F = 0
Correct answer: B
The force of gravity acting on the object on the moon can be found by multiplying its mass by the acceleration due to gravity on the moon. The acceleration due to gravity on the moon is a constant and is approximately 1.63m/s².
120kg×1.63m/s²=195.6kg.m/s²
kg.m/s²=N
<span>The force of gravity acting on the object on the moon would be of approximately 196N.</span>
Answer:
d. light microscopy allows one to view dynamic processes in living cells.
Explanation:
One advantage of light microscopy over transmission electron microscopy is that light microscopy allows one to view dynamic processes in living cells.
Electron microscope differ from the light microscope because electron micoscope produce the image of the specimen using electron beam and not light. Electron microscopy samples must be kept in vacuum, this means live cells can not be imaged.
My estimate is 1/2 inch per week.
(0.5 inch/wk) x (1 wk / 7 da) x (1 da / 86,400 sec) x (1 meter / 39.37 inches)
= (0.5 x 1 x 1 x 1) / (7 x 86,400 x 39.37) meter/second
= 1 / 47,621,952 meter/second
= 0.0000000209987... m/s
= 2.1 x 10⁻⁸ meter/second
= 2.1 x 10⁻⁵ mm/sec
= 0.000021 millimeter per second (rounded)
