First let us calculate for the angle of inclination using
the sin function,
sin θ = 1 m / 4 m
θ = 14.48°
Then we calculate the work done by the movers using the
formula:
W = Fnet * d
So we must calculate for the value of Fnet first. Fnet is
force due to weight minus the frictional force.
Fnet = m g sinθ – μ m g cosθ
Fnet = 1,500 sin14.48 – 0.2 * 1,500 * cos14.48
Fnet = 84.526 N
So the work exerted is equal to:
W = 84.526 N * 4 m
<span>W = 338.10 J</span>
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. ... Temperatures are certain to go up further. Despite ups and downs from year to year, global average surface temperature is rising.
Answer:
0.152 m
Explanation:
The condition for constructive interference is
d sinθ= mλ (m= 0,1,2,3...)
the slit width
d= 1/N
d= 10^(-3)/520
= 1.92×10^(-6)
The angular spread for the red light is
= 19.97°
The angular spread of blue light is
=14.66°
The distance between the first order red fringe and blue fringe is,
y= y_r- y_b = Ltanθ_r -Ltanθ_b
=1.50( tan19.97°-tan14.66°) = 0.152 m
The answer is evolution. When a specifies evolves over time they change and adapt to their environment.
Yes the sun has a greater gravitational force than Jupiter <span />
