1 Newton is equal to 0.22480894 pounds (force)
So you must multiply the magnitude of 15 Newtons by this conversion value to obtain the equivalent magnitude in units of pounds (force):
(15 N)*(0.22480894 N/lbf) = 3.37 lbf rounded to the nearest hundredth
Answer:
196 J
Explanation:
GPE= ham
GPE= (5)(9.8)(4)
GPE= 196 J
Answer:
Beaufort Scale
Explanation:
Sir Francis Beaufort, an Irish hydrographer, devised a scale to measure the wind speed in 1805. He devised this scale when he was serving on <em>HMS Woolwich</em>. Known as <em>Beaufort Wind Force Scale, </em>it measures and relates the speed of wind to conditions observed at land or sea. It was first used and officially adopted in 1830 on HMS Beagle where Robert Fitzroy was the captain.
No standard scale was present before the Beaufort scale. Initially, it had 13 classes (0-12) which related the wind condition quality and its effects on sails of a frigate. It was further extended in 1946 with addition of 5 more classes (13 to 17). Although, nowadays this extended scale is used only in mainland China and Taiwan.
Wind speed (as per 1946 scale):
m/s
where,
v = equivalent speed of wind 10m above the surface of the sea
B = Beaufort Scale number
C. Testable and observable
Answer:
Therefore the direction is in the <u>positive direction of the z axes</u>.
Explanation:
Let's recall that the magnetic force is given by:
The unit vector of V is and the unit vector of B is
So, the direction of the force will be defined as the cross product of i and j, and using the right hand rule:
Therefore the direction of the magnetic force is in the <u>positive direction of the z axes</u>.
