Answer:

a = 1.666... m/s²

Explanation:

a = v2 - v1 / t2 - t1

a = 21m/s - 14m/s / 6s - 0s

a = 7m/s / 6s

a = 1.666... m/s²

You drop an ice cube into an insulated flask full of water and wait for the ice cube to completely melt. The ice cube initially
3241004551 [841]

Answer:T=12.69^{\circ}C

Explanation:

Given

Mass of ice m=60 gm

mass of water M=760 gm

Initial Temperature of water T_i=20^{\circ}C

Let T be the Final Temperature of mixture

Latent heat of Fusion L=334 J/gm

heat required to melt ice completely is

Q_1=60\times 334=20.04 kJ

Heat released by water is taken by ice thus

Mc_{water}(20-T)=mL+mc_{water}(T-0)

0.76\times 4.184\cdot (20-T)=20.04+0.06\times 4.184\cdot (T)

T=12.69^{\circ}C

Two sound waves are traveling through the same medium. They have the same amplitude, wavelength, and direction of travel. If the
Sloan [31]

Answer:

Constructive interference

Explanation:

Here, the medium is same, same wavelength, same frequency, same amplitude and same direction of propagation.

Let the intensity of waves be I which is same for both

The formula for the net intensity is

I^{2}=I_{1}^{2}+I_{2}^{2}+2I_{1}I_{2}Cos\phi

where, Ф be the phase difference

So, I_{R}^{2}=I^{2}+I^{2}+2IICos6\pi

Here, IR is maximum so the interference is constructive in nature.
