Suppose you were to reduce the radius of the circular path of a ball on a string by one-half without changing the speed. How would that affect the size of the inward force (tension) in the string...

A particle in shm has a time period of 4s. It takes time t1 to start from mean position and reach half of the amplitude. In another case, it takes a time t2 to start from extreme position and...

Two tuning forks vibrate at frequencies f1 and f2 respectively (f1 ≠ f2) and produce sound waves of equal amplitude. Describe how the sound intensity heard by an observer varies and explain, with...

I need to create an excel graph that demonstrates Coulomb's law with realistic data

For orbiting satellites, the mass of the satellite always cancels in our centripetal force equation. Use the equation to justify why it is the satellite’s mass, and not the mass of the central planet,...

Consider a FBD provided for a toy car turning a corner. a) Which force here could be called the centripetal force? b) Write a horizontal FNET equation and identify the acceleration...

Mark and Sue are spinning together on a merry-go-round. Mark yells across to Sue “Why are you on the outside far from the centre? According to the equation there is an inverse relation between...

A favourite swimming hole includes a rope swing from an elevated landing. The boy swings down and releases with a velocity of vf at the bottom of the swing. Use Energy, then Dynamics to determine...

Our sun orbits around the centre of our galaxy (the Milky Way) once every 2.5 x 108 years. The radius of the sun’s orbit about the centre of the galaxy is approximately 3.15 x 1020 m. The sun has...

1. The frequency of light coming out from a laser source is 368 MHz. What is the wavelength corresponding to the light in meter provided that the speed of light inside the medium is 1.8 x10^8 m/s...

A neutron of mass u traveling with a speed 5.00x105 m/s collides with a stationary alpha particle of mass 4u. The neutron scatters off the alpha particle at an angle 65˚ with...

An object of mass m, initially at rest under the action of a constant force F attains a velocity v in time t. Then the average power is supplied to mass is ?

Express your answer in units of joules.

1) Calculate the energy in eV corresponding to the 500 nm of light inside a medium with refractive index 1.2. 2) The frequency of light coming out from a laser source is 142 MHz....

The escape velocity applies to any object regardless of its mass. Even very small particles, such as atmospheric gases, can reach escape velocities. Gas molecules at 20°C move with a velocity of approximately...

A favourite swimming hole includes a rope swing from an elevated landing. The boy swings down and releases with a velocity of vf at the bottom of the swing. Use Energy, then Dynamics to determine...

What is the answer to the question

In detail, thanks for answering x

John and Barry are pulling on a fence post with ropes while their friend Pat uses a chainsaw to share it at ground level. John applies a force of 75.0 N [40 degrees] on one rope while Barry applies...
