Call me skeptic, but as soon as I saw the beginning of the question, I was convinced that when I opened it, there would be no figure there. So I opened it, and sure enough, there is no figure here.
Notice the first instruction in the question. It says "Use the figure ..." .
That's where we would find the information we need to answer this question ...
like the lengths of the wires, and the angles they make with the body ... all of
that stuff that's in the figure but you decided not to share.
I'll get right on it as soon as you show me the figure.
One
A wire carrying a current creates a circular field. Not A.
B is pretty uniform. I would pick it.
C The lines bend around the north and south poles. Not C
D Same Remark as C.
Two
- The force exerted by the magnetic field is the palm of your right hand.
- Your thumb is the direction of the charged stream
- The fingers are the direction of B which I take to be into the page.
If all these are in agreement with what you think you have been given then A is the correct answer. The proton will be defected in the direction of the palm.
Three
As stated in One the fingers point in the direction of B, The thumb is the direction of the charge and the palm is the direction of the force when the item is a plus charge. When the travelling charge is minus as this one is, use the back of your hand. In that case, The electron will be deflected downward. This assumes the Magnetic field is pointing into the page.
The answer is A.
Answer:
0.0757 kg
Explanation:
m = mass of the body = 95 kg = 95000 g
ΔT = change in the temperature of the body = 0.45 °C
c = specific heat capacity of the body = 4.0 J/(g °C)
M = mass of water evaporated
L = latent heat of vaporization of water = 2260 J/g
Using conservation of heat
Heat gained by water = heat lost by body
ML = m c ΔT
M (2260) = (95000) (4.0) (0.45)
M = 75.7 g
M = 0.0757 kg
Answer:
Acceleration due to gravity 9.8 m/s^2
Explanation:
When an object drops down towards earth from certain height than it comes down with an acceleration of 9.8 m/s^2 which is constant throughout the dropping until the falling objects hits the ground and coming to rest.
Every object in the universe that has mass<span> exerts a gravitational pull, or </span>force<span>, on every other mass. </span>
