Answer:
Reflection
Explanation:
<em>The particles in the atmosphere only reflect the color blue and and all others are absorbed. Only the reflected colors can be seen from our eyes not the absorbed ones</em>
Answer:
Explanation:
Under the definition of force on a magnetic field we proceed to make the point a,
A)
Since the field is perpendicular, then \theta = 0
b) The direction of the magnetic field would be done in + Zdirection. This when understanding that the vector extends along the z + axis of the formula
Answer:
Work done by the gas for the given volume and pressure pounds foot
Explanation:
Given
Pressure applied pounds per square foot
Initial Volume cubic feet
Final Volume cubic feet
As we know pressure is inversely proportional to V
where k is the proportionality constant
V is the volume and
P is the pressure
Work done
Integrating the above equation, we get-
Work done by the gas for the given volume and pressure pounds foot
Answer:
The shear modulus of the polymer is 5 MPa
Solution:
As per the question:
displacement of the top plate, d = 2 mm = 0.002 m
Horizontal Force, P = 2 kN = 2000 N
Width of the block, w = 100 mm = 0.1 m
By small angle analysis:
Angle,
Now,
Stress, =
1 watt means 1 joule of energy per second
The food processor uses 1,150 joules of energy per second.
The blade uses 950 joules per second to slice, dice, and puree.
The rest of the energy goes to heat the appliance's motor, or
overcome friction in the blade's bearings, etc. How much energy
does NOT go into slicing and pureeing ?
(1,150 watts) - (950 watts) = 200 joules per second
1 minute = 60 seconds
2 minutes = 120 seconds
Energy wasted in 2 minutes =
(200 joules/second) x (120 seconds) = <em>24,000 joules</em>
That's enough energy to operate a 34-watt CFL (curly) light bulb
for 11 minutes 46 seconds.
