One takes longer to slow down than the other because one has more mass(the train) compared to the bowling ball!

One 10.0 amp resistor is wired in a series with two 10.0 amp resistors in parallel. A 45.0 C battery supplies power to the circu

Marat540 [252]

It's not possible to calculate the current with the given data. "Amp" is not a unit for measuring resistors, and "C" is not a unit for measuring batteries. So we don't know the resistance of this circuit or the potential difference applied to it, and thus can't calculate the current. If we could, it might turn out to be 3 gallons, but that's just a reckless guess.

Light from a helium-neon laser (λ=633nm) passes through a circular aperture and is observed on a screen 5.80 mm behind the apert

Helga [31]

Explanation:

Whenever the light passes through hole or slit then it tends to bend that is actually a diffraction. It will then made the interference pattern of light and dark bands that due to constructive and destructive interference.

So by using the equation of diffraction,

dsinA = nL

SinA is a geometric component it can be written as,

$d\frac{y}{x} = nL$

∵ x is the distance from screen.

∵ y is the half of the width of central maximum.

now by putting the values in mm,

$d\frac{17}{5.80} = 0.000633$

d = 2.15× $10^{-4}$ mm

Two Objects of the same size will always have the same mass” Is this statement correct?

attashe74 [19]

No, they won't, mass coincides with density and objects have different densities a one pound lead ball would be smaller than a one pound copper one.

Kipish [7]

Vector resolution will be used to answer this question as the boat's velocity will have two components, one allowing it to travel across the river and the other taking it downstream.
