If Team 4 wants to increase the horizontal distance that the skittles are projected through the air but keep the height as close
photoshop1234 [79]

Answer:

The speed of the catapult arm needs to be increased.

Explanation:

If the height needs to stay the same, they can not change the length of the catapult arm because this is the variable that determines the height of the thrown object. To change the horizontal distance the object travels, in other words the object's speed, the rope or counterweigth that pulls the catapult arm can be changed to increase the speed that the object is thrown.

I hope this answer helps.

If a 8860 N horse has been lifted 4.5 meters by a crane, what work does it have?
Lana71 [14]
<span>Data:
W (work) = ? (Joule)
P (weight) = 8860 N
h (height) = 4.5 m

Formula:
</span>W = P*h
<span>
Solving:
</span>W = P*h
W = 8860*4.5
\boxed{\boxed{W = 39870\:Joule}}\end{array}}\qquad\quad\checkmark

What is the length of a one-dimensional box in which an electron in the n=1 state has the same energy as a photon with a wavelen
Pie

Answer:

Length will be 0.491 nm

Explanation:

We have given wavelength of the photon \lambda =800nm=800\times 10^{-9}m

Plank's constant h=6.6\times 10^{-34}J-s

We know that energy of the photon is given by

E=\frac{hc}{\lambda }=\frac{6.6\times 10^{-34}\times 3\times 10^8}{800\times \times 10^{-9}}=2.475\times 10^{-19}J

We know that energy of photon is also given by

E=\frac{n^2h^2}{8mL^2}=\frac{h^2}{8mL^2}

2.475\times 10^{-19}=\frac{(6.6\times 10^{-34})^2}{8\times 9.1\times 10^{-31}\times L^2}

L=0.491\times 10^{-9}m
