64. 16x16 = 4 so 9x9 divided by 2 equals 7
The first step of the scientific method is to MAKE OBSERVATIONS
Frequency is indirectly proportional to the wavelength, in other words, when frequency increases wavelength decreases and vice-versa
c = ∧f
Hope this helps!
The magnitude of the quantity and its direction.
Answer:
21.22s
Explanation:
initial velocity u=87m/s
acceleration a=-4.10 m/s²
velocity v=0
time t=?
From Newton's first law of motion
V=u+at
0=87-4.10t
-87=-4.1t
t= -87/-4.1
t= 21.22 s
