Answer:
The minimum angular velocity of the platform what whould the block slides away is w= 2.26 rad/s.
Explanation:
m= 0.265 kg
r= 2.4 m
μ= 0.257
g= 9.8 m/s²
W= m * g
W= 2.597 N
Fr= μ * W
Fr= 0.66 N
∑F = m * ac
W+Fr = m * ac
(W+ Fr) / m = ac
ac= 12.29 m/s²
ac= w² * r
√(ac/r)= w
w= 2.26 rad/s
Answer:
Nature of Sound Waves Sound is a wave that is created by <u>perturbations</u> and propagated through a <u>medium</u> from one location to another. Type of Wave: <u>longitudinal wave</u><u>.</u> A sound wave consists of a repeating pattern of high-pressure and low-pressure regions moving through a medium Sound needs a <u>medium of propagation</u> and a <u>disturbance.</u> Like any wave, the speed of a sound wave refers to how fast the disturbance is passed from particle to particle. Anatomy of a Wave:
The magnitude is 4×10⁻⁵T and direction of the magnetic field at a point p is -z axis.
we know that magnetic field due to a long straight wire at a point perpendicular to it is given by
B=(μ°I)/2πR
μ°= 4π×10⁻⁷Hm⁻¹
R=2cm
I=4A
on substituting value we get
B=(4π×10⁻⁷×4)/2π×2×10⁻²
B=4×10⁻⁵T
the direction will be along negative Z axis, outside the plane
