A piston oscillates vertically at 3.7 Hz. Find the maximum oscillation amplitude so a coin resting atop the piston doesnt come off at any point in the cycle.-The max acceleration of piston will be equ
A block of birch wood floats in oil with 90.0% of its volume submerged. What is the density of the oil? The density of the birch is 0.67 g/cm ^3-A body displaces a volume of liquid. The weight of the
We all know that carbon dioxide freezes on temperature -78.5 degrees celsiusbut i particularly want to know at what pressure does carbon dioxide form solid carbon dioxide also known as frozen ice .-Th
who weights 200N is standing 4m from the supported end, then what is the tension in the string and the reaction force at the supported end??-You have 2 different answers. So you need a tie breaker. Il
A charge q1 = 5 µC, is at the origin, and a second charge, q2 = -3 µC, is on the x-axis 1 m from the origin. Find the electric field at a point on the y-axis 0.5 m from the origin.
Magnitude of Field
A person, driving a golf ball off a tee, gives the ball a velocity of +28 m/s. The mass of the ball is 0.045 kg, and the duration of the impact with the golf club is 6.0 x 10-3 s.
a) What is the momen
When a scarlet or crimson object is viewed through a red glass in the LIGHT, the object APPEARS white.
Why/How?
10 points! Please list how you know.-When light hits a red object, that means all vis
An electric field of 32 x 104 N/C is directed along the positive x-axis. What is the electric force on an electron in this field?
a: Magnitude of Force:
b: Direction of Force [enter as angle between
An elastic circular conducting loop expands at a constant rate over time such that its radius is given by r(t) = r0 + vt, where r0 = 0.290 m and v = 0.0230 m/s. The loop has a constant resistance of R
Please help explain the formula and all of the steps involved in getting the answer.
Answer is in K
Thanks!-You can use Wiens displacement law to find out the temperature.
λmax=b/T
Rearrange it to
Assume a transparent rod of diameter d = 3.19 µm has an index of refraction of 1.33. Determine the maximum angle θ (in degrees) for which the light rays incident on the end of the rod in the figure be
In physics, what does an inertial frame mean?-The reason this is tricky is because all of Newtons Laws together define inertial frames, as a state of motion from which Newtons laws are observed to hol
At least for me, the many worlds interpretation comes from an assumption of exactly one universal wavefunction. Different terms in this wavefunction correspond to the different worlds, and we happen t
Matters really. One of the reasons that relativity was so mind blowing was that it was not a common idea that people well respected. It is useful in electronics as well as nuclear processes. However,
a.1.7m3
b.0.97m3
c.0.45m3
d.0.78m3
e. 2.4m3-converting 4450 N to kg, that is 4450/9.8 = 454 kg
density of fresh water at 20C= 998 kg/m³, so the water displaced is
454 kg / 998 kg/m³ = 0.455 m³ (c)
