Make equipment work independent.
Answer:
a. Value of MA is always lesser than VR because mechanical advantage decreases due to the friction and weight of moving parts of the machine.
b.Efficiency of lever is never 100 or more because it will always lose some tiny (sometimes immeasurable) percentage of power due to the lever bending.
c.Because it helps to apply more torque.
d.Because the upright snip has the blades rotated 90° from the handles.
e.because some of the input work is used to overcome friction.
f.because the load arm is always longer than effort arm.
g.because the effort arm is always longer than load arm of these Lever.
h. because if the effort distance is greater than load distance there will be magnification of force and the metals could easily cut.
i. because the wheelbarrow's wheel and axle help the wheelbarrow to move without friction thus making it easier to push or pull.
Answer:
ATMOSPHERIC PRESSURE HAS IMPORTANT EFFECTS ON WATER CHEMISTRY AND WEATHER CONDITION . IT AFFECTS THE AMOUNT OF GAS THAT CAN DISSOLVE IN WATER. LIKE OXYGEN CAN DISSOLVE IN HIGH PRESSURE MORE THAN LOWER AIR PRESSURE.
Answer:
a
The value of magnetic field is 
In the direction of the positive x - axis
b
The value of magnetic field is
In the direction of the positive z - axis
Explanation:
From the question we are told that
The velocity of the electron is 
Considering the first position
The equation for the magnetic field is
Now 
substituting values
Therefore 
So Substituting 
for 
, 
for q
Considering the second position
Here
So Substituting for , for q
"Traditionally, physical science courses are categorized into four areas: physics, chemistry, earth sciences, and space sciences. It is important to understand that the arbitrary divisions of specialized knowledge are integrated into a basic overview of the physical laws that govern our universe." - Cameron University
