Answer:

Change in potential energy is 700.7 J.

Explanation:

Given:

Mass of the object is, m=286 kg

Height to which the object is raised above his head, h=0.25 m

Acceleration due to gravity is, g=9.8 m/s²

We know that for a mass m raised to a height h, the change in potential energy is given as:

\Delta PE=mgh, where, \Delta PE\rightarrow \textrm{Change in Potential Energy}

Now, plug in the given values and solve.

\Delta PE=286\times 9.8\times 0.25=700.7\textrm{ J}

Therefore, the change in the potential energy is 700.7 J.

Look at the diagram. Emily needs to complete the circuit. What two points should be connected to complete the circuit and make t
pogonyaev

Answer:

The points 2 and 4 should be connected.

Explanation:

To complete the circuit, we need to connect the two points which when connected, encompass the battery and the bulb in the circuit. The points 2 and 4 do the job, since they connect the terminal of the battery and the terminal of the bulb, and thus complete the circuit.

Therefore,  the choice C is correct.

An open organ pipe of length 0.47328 m and another pipe closed at one end of length 0.702821 m are sounded together. What beat f
sineoko [7]

Answer:

fb = 240.35 Hz

Explanation:

In order to calculate the beat frequency generated by the first modes of each, organ and tube, you use the following formulas for the fundamental frequencies.

Open tube:

f=\frac{v_s}{2L}         (1)

vs: speed of sound = 343m/s

L: length of the open tube = 0.47328m

You replace in the equation (1):

f=\frac{343m/s}{2(0.47228m)}=362.36Hz      

Closed tube:

f'=\frac{v_s}{4L'}

L': length of the closed tube = 0.702821m

f'=\frac{343m/s}{4(0.702821m)}=122.00Hz

Next, you use the following formula for the beat frequency:

f_b=|f-f'|=|362.36Hz-122.00Hz|=240.35Hz

The beat frequency generated by the first overtone pf the closed pipe and the fundamental of the open pipe is 240.35Hz

Shaping will happen if _____.
Pavlova-9 [17]
What is being done in shaping is that it directs and guides the change in one's behavior. Therefore, what will happen when one undergoes shaping is that you encourage a lot of minor behaviors which would add up to one large action. The answer to this would be the first option.
