Answer:
B. develop hypotheses that will be subjected to empirical test.
Explanation:
The rational method of inquiry is most useful in the early stages of science to develop hypotheses that will be subjected to empirical test.
Answer:
Positive Z direction (out of screen)
Explanation:
Magnetic force is given by 
. A quick way to gauge the components is to put your left middle finger on the direction of the current, your index on the direction of the magnetic field, and the thumb gives you the answer you want.
Hi,
The force that acts on hydraulic machine is heavy therefore the content must be something that cannot be compressed by that kind of force, the gas can easily be compressed while a liquid is nearly impossible to.
The integral of acceleration is velocity. The area under the curve is an integral. You can see the relation here. So just take the area under those time intervals. I’m assuming 1.7 is where it crosses the x-axis
For the first interval:
Base = 1.7
Height = -2
[1.7*(-2)]/2 = -1.7 cm/s
For the second interval:
There are two triangles and a rectangle here.
Base #1 = 0.3
Height #1 = 1
Base #2 = 1
Height #2 = 1
Length = 3
Width = 1
Apply the area formulas to get an answer of 3.65 cm/s
Answer:
- 256 lbs
Explanation:
The internal axial load at point D can be calculated as the change in the subjected loads. if the magnitude of the horizontal direction = zero
; Then:
internal axial load at point D = Δ P
= -(P₂ - P₁)
= - ( 888 lbs - 632 lbs)
= - 256 lbs
