Answer:
0.10 m
Explanation:
The magnetic flux through the plane is given by
where
B is the magnetic field intensity
A is the area of enclosed by the pipe
In this problem, we know
is the flux
B = 0.90 T is the magnetic field strength
Solving the equation for A, we find the area enclosed by the pipe
We know that the area is given by
where r is the radius. Solving for r, we find the radius:
And so the diameter is twice the radius:
The answer
<span>According to Newton’s first law, if no force acts on an object, it will just continue moving in a straight line with a constant speed or at rest
that means that the sum of all acting forces equals 0
</span>so the car must
exert a force between the car and the road to drive at a constant speed on a straight and level road because the both forces must be balances for making it to move <span><span>with a constant speed in a straight line.</span> </span>
We have particle A which is curved to the left-hand side.
Particles B is slowly bent to the right side.
Particle C curves towards the right side.
Particle D is perpendicularly straight.
The particle E bends towards the right side.
Therefore D is showing none deflection then it is the part D which is neutral
Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
Answer:
0.0804 m / h
Explanation:
r = 1 m, dr / dt = 8 cm/h = 0.08 m/h
the volume of sphere is given by
V = 4/3 x π x r^3
Differentiate with respect to r.
dV / dr = 4 / 3 x π x 3 r^2 x dr/dt
dV/dt = 4 x π x r^2 x dr/dt
dV/dt = 4 x 3.14 x 1 x 1 x 0.08
dv/dt = 0.0804 m / h
