Jack Nicklaus once said about golf that "hitting a perfectly straight shot with a big club is a fluke." Science of Golf (SOG): Newton’s Third Law of Motion and Momentum explains what happens when a golfer swings a golf club and applies a big force to the small golf ball. The video features amateur golfer and Stanford University student Patrick Rodgers who gives his opinion on the importance of knowing what causes power and speed in the golf swing. Jim Hubbell, research engineer at the United States Golf Association (USGA) discusses what forces are and how they work in pairs. Hubbell also defines momentum and how it is transferred to the ball.

Hope this helps

What happens to the deflection when we increase the number of turns of wire

Katyanochek1 [597]

Answer:

<u>Because the amount of the field is exactly related to the strength of the electric current, the deflection increases as the current increases. That is, as the electric current increases, so does the magnetic field.</u>

Explanation:

The acceleration due to gravity on earth $g_{E}$ is given by

$g_{E} = G\dfrac{M_{E}}{R_{E}^{2}}$

where $G$ = universal gravitational constant

$\:\:\:\:\:\:\:\:\:\:\:\:M_{R}$ = mass of the earth

$\:\:\:\:\:\:\:\:\:\:\:\:R_{E}$ = radius of the earth

Planet Krypton has twice the mass of earth and 3 times the radius so its acceleration due to gravity $g_{K}$ is

$g_{K} = G\dfrac{M_{K}}{R_{K}^{2}}$

$\:\:\:\:\:\: = G\dfrac{(2M_{E})}{(3R_{E})^{2}}$

$\:\:\:\:\;\:= (\dfrac{2}{9})G\dfrac{M_{E}}{R_{E}^{2}}$

$g_{K} = (\dfrac{2}{9})\:g_{E}$

If we multiply both sides by Superman's mass, we get his weights on both planets:

$mg_{K} = (\dfrac{2}{9})\:(mg_{E})$

$W_{K} = (\dfrac{2}{9})\:W_{E} = (\dfrac{2}{9})(900\:N)= 200\:N$

A container with 0.485 L of water is placed into microwave and is then radiated with electromagnetic energy that has a wavelengt

Brut [27]

Calculate the energy (J) increase due to heating. Then: Use energy per photon = h f = (Planck's constant)(frequency) frequency = (speed of light)/(wavelength) Divide: energy gain/energy per photon = number of photons
