This direction is independent of the test dipole, and only depends on the orientation and distance of the magnetic dipole. The force this unit dipole experiences, is the magnetic field at that point. As you can see, this quantity requires a unique direction for compete understanding. Therefore, it is a vector quantity.
Answer:
a) t = 0.113 s
, b) W = 0.1756 N
, c) # λ = 49
Explanation:
a) Let's use the relationship
v = λ f
Of the equation
y = 8.55 10-3 cos (172 x + 2730 t)
When comparing this with the general equation
y = A cos (kx - wt)
The wave number k = 172
k = 2π /λ
λ = 2π / 172
λ = 0.03653 m
The angular velocity w = 2730
w = 2π f
f = w / 2π
f = 2730 / 2π
f = 434.49 Hz
The speed of the wave is
v = 0.03653 434.49
v = 15.87 m / s
The speed the wave on a string is constant, so
v = d / t
t = d / v
t = 1.80 /15.87
t = 0.113 s
b) The weight applied to the rope
v = √ T /μ
The density
μ = m / l
μ = (0.0123 / 9.8) /1.80
μ = 6.97 10-4 kg / m
The tension equal to the applied weight
T = v² μ
W = T = 15.87² 6.97 10⁻⁴
W = 0.1756 N
c) let's use a rule of proportions
# λ = 1.8 /0.03653
# λ = 49
Simply put, our solar system is a speck compared to the Milky Way. Our Milky Way galaxy is a whopping 587 trillion light-years across.
Answer:
2.27kg
Explanation:
The Potential energy gained = Force gravity× Height
Force gravity on the ball is GPE/ height
56.8/2.5=22.72N
the mass = 22.72/10= 2.27kg
Air resistance is a force that slows down objects moving through the air. ... Objects are affected by gravity the same, but air resistance can affect the speed of an object's descent. An object with more surface area will have more air resistance.
