Answer:
OK HERE
Explanation:
When raising a power to a power in an exponential expression, you find the new power by multiplying the two powers together. For example, in the following expression, x to the power of 3 is being raised to the power of 6, and so you would multiply 3 and 6 to find the new power.
I would say B
Because technically if your just holding it your not doing anything

Answer:
<em>The fringe spacing on a distant diffraction screen will increase.</em>
Explanation:
Blue light has a shorter wavelength than red light, so, changing from blue to red light is basically increasing the wavelength of the light involved in the experiment.
In the double slit experiment, the fringe spacing on a diffraction screen is calculated from the equation below
ω = zλ/d
where ω is the fringe spacing
z is the distance of the slit to the screen
λ is the wavelength of the light used
d is separation or distance between the slits
From the equation, one can see that if other parameters are held constant, <em>increasing the wavelength will lead to an increase in the spacing between the fringes, and hence, changing the light from blue to red light will increase the fringe spacing.</em>
Answer:
The work done on the canister is 15.34 J.
Explanation:
Given;
mass of canister, m = 1.9 kg
magnitude of force acting on x-y plane, F = 3.9 N
initial velocity of canister in positive x direction, = 3.9 m/s
final velocity of the canister in positive y direction,
The change in the kinetic energy of the canister is equal to net work done on the canister by 3.9 N.
ΔK.E =
ΔK.E
The initial kinetic energy of the canister;
The final kinetic energy of the canister;
ΔK.E = 29.79 J - 14.45 J
ΔK.E = = 15.34 J
Therefore, the work done on the canister is 15.34 J.
I'm assuming by the phrasing of your question that you are looking for examples of simple machines that are not wedges.
Well, there are five other simple machines. There is a pulley, lever, screw, wheel and axle, and an inclined plane.
Hope that helped you!
