An electron is constrained to the central perpendicular axis of a ring of charge of radius 2.7 m and charge 0.027 mC. Suppose the electron is released from rest a distance 0.035 m from the ring center. It then oscillates through the ring center. Calculate its period. (The electron is always much closer to the ring center than a radius.)
The period is mathematically given as
t=7.34*10^{-8}s
What is the period?

The system is in equilibrium, and the pulleys are weightless and frictionless.
Find the tension T.
The acceleration of gravity is 32 ft/s^2
Note: lb ≡ slug · ft/s^2
Answer in units of lb.
There is an attachment of the system below
Answer:
F = M a where F is in lbs, M in slugs and a in ft/s^2
Apparently this system is motionless so
T + 15 is the downward force on the mass of 15 lbs
1 slug * 32 ft/s^2 is 32 lbs the weight of the other block
It takes a force of 32 / 2 = 16 lbs on the cable to support this weight
16 lbs = T + 15 lbs
T = 1 lbs

A body of mass 10 kg is being rotated in a circular path of
diameter 1.0 mm on a frictionless horizontal plane by means of
a string. It performs 10 revolutions in 3.14 s. Calculate the
centripetal force acting on it.
Answer:
The answer is 2N
Explanation:
Given;mass (m) = 10 kgDiameter (d) = 1 mmTo Find;The centripetal force acting on it.Now,
Radius (r) = Diameter ÷ 2
r = 1/2
r = 0.5 mm = 5 × 10‾⁴
T = 3.14 ÷ 10 = π/10 sec
∴ F = mrω² = mr (2π/T)² = 4π²mr/T²
F = 4 π² × 10 × 5 × 10‾⁴/(π/10)²
F = 4 π² × 10 × 5 × 10‾⁴ × 100/π²
F = 4 × 0.5
F = 2 N
Thus, The centripetal force acting on it is 2 Newton

A particle with charge q, mass m, and initial speed v0 in the x direction enters a region where the electric field is uniform in the x direction. How much time does it take for the particle to cross the region of length d
Answer:
S = 1/2 Vo t + 1/2 a t^2 = d time for particle to travel distance d
F = E q force acting on particle
a = F / m = E q / m
d = Vo t + E q / (2 m) t^2
One would need to solve the quadratic equation shown to find the time t
t^2 + (2 m) / E q * V0 t - (2 m) / E q * d = 0
or t^2 + A V0 t - A d = 0 where A = (2 m) / E q

A student notices that a basketball seems to act differently depending on whether the game is being played on a court with a wooden floor, on a concrete driveway, or on blacktop in a park. The student hypothesizes that the surface on which a ball is bounced affects the height of the bounce. How can the student design an experiment to test the hypothesis?
A.The student should drop the same ball from three different heights and have someone measure the height of each bounce.
B.The student should drop three different balls from the same height and have someone measure the height of each bounce.
C.The student should drop the same ball from the same height on three different surfaces and have someone measure the height of each bounce.
D. The student should drop three different balls from the same height on three different surfaces and have someone measure the height of each bounce.
Answer: Experimental design means creating a set of procedures to test a hypothesis. A good experimental design requires a strong understanding of the system you are studying. By first considering the variables and how they are related ( Step 1 ), you can make predictions that are specific and testable
Explanation:
A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research, in a process beginning with an educated guess or thought.
How is the answer d??
Answer:
To keep from falling at the top;
M V^2 / R = M g
This can be rewritten
1/2 M V^2 = M g R /2
2 M g R = 1/2 M V^2 difference in KE between top and bottom
2 M g R + M g R / 2 = 5/2 M g R
Adding the minimum KE at the top to the KE gained when the potential energy of 2 M g R is converted to KE
