Answer:
Explanation:
The magnitude of the acceleration in the x direction is always zero: TRUE.
At the apex, in the y direction the velocity is zero and the accelration is positive. TRUE.
At the apex, in the x direction, the velocity is zero and the acceleration is zero. FALSE. The accelration is zero, but the velocity is the same it had when it was shot.
The magnitude of the velocity in the y direction is always constant. FALSE, it's subject to gravity and it's velocity varies as 
At the apex, in the Y direction, the velocity is negative and the acceleration is zero. FALSE. Velocity is zero, Acceleration is 
, towards the negative y axis
Answer:
False. Astrology is not a science.
Explanation:
Astrology is a collective term for ideas about the supposed connection between the fate of people and events on Earth and the position of the celestial bodies. It mainly concerns the places in the sky of the sun, moon and planets, which were referred to as stars in ancient times, usually against the background of the fixed stars in the Zodiac. Although astrology cannot be confirmed despite research, and scientists have long rejected the principles of astrology as pseudoscience, many people continue to practice and / or believe in it.
We want a sound wave with a wavelength of 0.52 meters or a natural fraction thereof. We'll work in MKS.
w = 0.52/n
That's length. We have speed 344 meters/second so w corresponds to a frequency of
f = 344 / w = n (344/.52)
f = 661.5 n Hertz
I don't really agree with how they're saying it, but all the fundamental talk is probably trying to tell us n=1,
Answer: 661.5 Hertz
Any multiple of that will also produce constructive interference; we can go to about n=30 before we're out of the audio range.
Answer:
25N.s=25kgm/s
Explanation:
The resulting momentum in this case is equal to the impulse created by the force 5N during 5 seconds
ΔP=Force.time=F.t
= 5x5=25kgm/s
