Answer:
D. The water on her skin evaporates quickly and cools her skin.
Explanation:
The potential energy as it reaches a height of 0.63 meters is mgh
Since total mechanical energy is conserved, Set that equal to the initial kinetic energy which is 0.5mv^2
2*9.8*0.63 = 0.5*2*v^2
12.348 = v^2
3.51 = v
That's it's initial speed.
Answer:
Explanation:
Force on a moving charge is given by the following relation
F = q ( v x B )
for proton
q = e , v = vi , B = Bk
F = e ( vi x Bk )
= Bev - j
= - Bevj
The direction of force is along negative of y axis or -y - axis.
for electron
q = - e , v = vi , B = Bk
F = - e ( vi x Bk )
= - Bev - j
= Bevj
The direction of force is along positive of y axis or + y - axis.
The correct answer is C. The level of competition is not very high in most Masters programs.
Explanation:
In sports, the word "master" is used to define athletes older than 30 and that usually are professional or have trained for many years, although novates are also allowed. This means in most cases in Master programs and teams a high level of competition can be expected due to the experience and extensive training of Master athletes. Indeed, many records in the field of sport belong to Master athletes rather than younger athletes. According to this, the incorrect statement is "The level of competition is not very high in most Masters programs".
Answer:
77362.56 J
163730.28571 J
Explanation:
A = Area = 25 mm²
l = Length = 300 mm
K = Constant = 
= Heat transfer factor = 0.75
= Melting factor = 0.63
T = Melting point of low carbon steel = 1760 K
Volume of the fillet would be
The unit energy for melting is given by
Heat would be
Heat required to weld is 77362.56 J
Amount of heat generation is given by
The heat generated at the welding source is 163730.28571 J
