Answer:
gas
Explanation:
gasoline will never freeze up
Answer:
75.5degrees
Explanation:
Magnitude of magnetic flux= BA
If rotated through an angle= BAcos theta
= (0.25)BA=BAcos theta
= costheta= 0.25
= theta= cos^-1 0.25
=75.5degrees
Answer:
The entire cart/hanging mass system follows the same law, ΣF = ma. This means that plotting force vs. acceleration yields a linear relationship (of the form y = mx).
Answer:
a=8.06m/s^2
Explanation:
The box can be considered negligible body slidding down along a curved path defined by the parabola Y=Ax^2
Note:
When it's at A(x=2m, y=1.6m),
the speed Vb=8m/s and the increase in speed=4m/s^2
To find the acceleration,
Y=Ax^2
dy/dx=8x
d^2y/dx^2=8
p={[1+(dy/dx)^2]^3/2}/|d^2y/dx^2| .......1
substituting into 1, we have
p=8.39624m
an=v^2/p
an=8^2/8.39624=7.6224m/s^2
a=sqrt(at^2+an^2)
a=sqrt(4^2+7.62246^2)
a=8.06m/s^2
In working toward the complete solution of this problem,
I'm going to use addition, subtraction, multiplication, and
division. Also, I think I'll be using Newtons 2nd law of motion
like at least fifteen times, so I'll write it here for our review:
<span> Force = (mass) x (acceleration).</span>
-- When 36 N of force acts on m₁ it accelerates at 6 m/s² .
36 N = (m₁) x (6 m/s²)
Divide each side by 6 m/s² : m₁ = (36 N) / (6 m/s²) = 6 kg .
-- The same force acting on (m₁+m₂) accelerates them at 2 m/s² .
36 N = (6kg + m₂) x (2 m/s²)
Divide each side by 2 m/s² : 6kg + m₂ = (36N) / (2m/s²) = 18 kg
Subtract 6kg from each side: m₂ = 12 kg .
-- The same net force acts on m₂ alone:
36 N = (12 kg) x (acceleration)
Divide each side by 12 kg : Acceleration = (36 N) / (12 kg) = <span>3 m/s² </span>.
Hope this helps alot
