D. Jupiter has the highest amount of gravity in our solar system
Explanation:
It is given that,
Voltage, 
De broglie wavelength in terms of voltage is given by :

m and e are the mass and charge on electron. So,



So, the De broglie wavelength of an electron is 1.53 meters. Hence, this is the required solution.
Answer:
A)t=<u>1.375s</u>
B)t=11s
Explanation:
for this problem we will assume that the east is positive while the west is negative, what we must do is find the relative speed between the wave and the powerboat, and then with the distance find the time for each case
ecuations
V=Vw-Vp (1)
V= relative speed
Vw= speed of wave
Vp=Speesd
t=X/V(2)
t=time
x=distance=44m
A) the powerboat moves to west
V=18-(-14)=32m/s
t=44/32=<u>1.375s</u>
B)the powerboat moves to east
V=18-14=4
t=44/4=<u>11s</u>
Answer:
2.38 T
Explanation:
Since the number of coils and the change in time are both 1, I set it up as 3.57=1.50(x) and then solved for x to be 2.38 T.
Answer: B
To measure a lower-pitched sound wave, you would
measure fewer compressions per second. Pitch <span>relates to frequency by measuring how many times a second the
particles vibrate. Therefore, the lower-pitched sounds, the fewer compression waves or sound waves are produce because low-frequency
sounds have greater distance between each wave.</span>
Moreover,
the frequency of a wave is measured as the number of complete
back-and-forth vibrations of a particle of the medium per unit of time. <span>The universal unit for frequency used is
the Hertz (abbreviated Hz), where 1
Hertz = 1 vibration/second. </span>
