Answer:
it looks like light hits ballon and the bollon pops maby pop prosos
Answer:
The sphere is that the circular objects in the two-dimensional space (1) circle
(2) disk. Two-dimensional space is a set of points and the distance of that point, The two points of Sphere that length and center.
The sphere can be constructed as the name of surface form circle about any diameter. The circle is the special type of the revolution replacing the circle,
the sphere is the distance r is the radius of the ball and the circle is the center of the mathematical ball, as the center and the radius of the sphere is to respectively.
The ball and sphere have not to be maintained mathematical references as solid references. A sphere of any radius is centered at the number of zero.
Explanation: Hope this helps and good luck :)
A mechanical wave such as sound needs a medium to travel through. This is why they say that in space, no one can hear you scream (because space is a vacuum and no medium exists). On the contrary, light can exist in wave or particle form. This is why we have the ability to see beyond the realms of the Earth.
Answer:
Angular speed will reach 6.833rad/s before the coin starts slipping
Explanation:
There is no question but I'll asume the common one: Calculate the speed of the turntable before the coin starts slipping.
With a sum of forces:
At this point, friction force is maximum, so:
Solving for V:
V=1.025 m/s
The angular speed of the turntable will be:
ω = V/R = 6.833 rad/s This is the maximum speed it can reach before the coin starts slipping.
Answer:
Explanation:
Your question makes no sense.
moment of inertia is a property of the disk and its geometry.
The moment of inertia of a uniform solid disk around an axis through its geometric center and perpendicular to its flat ends is
I = ½mR² = ½(3.2)0.45² = 0.324 kg•m²
the applied torque about the same axis would be
τ = FR = 420.4(0.45) = 189.18 N•m
and the angular acceleration about the same axis would be
α = τ/I = 189.18/0.324 = 583.9 rad/s²
