A. meteor which object is usually found passing through the earth's atmosphere are meteor
Answer:
Explanation:
A)
vf² = vi² + 2(a)(d)
(54 m/s)² = (27 m/s)² + 2(a)(120 m)
a = 9.1125 m/s²
a = 9.1 m/s²
B)
d = (vi)(t) + (1/2)(a)(t²)
150 m = 0 + (1/2)(9.1125)(t²)
t = 5.7 s
C)
vf = vi + (a)(t)
27 m/s = 0 + (9.1125)(t)
t = 3.0 s
D)
d = (vi)(t) + (1/2)(a)(t²)
d = 0 + (1/2)(9.1125)(2.96²)
d = 40 m
Answer:
It should be option B polarization
Answer:
n = 1000 pulses
Explanation:
Given that,
The frequency of a pulse waveform,
To find,
The number of pulses counted during 100 ms.
Solution,
The frequency of a pulse waveform is equal to the number of pulses per unit time. It is given by :
n = 1000 pulses
So, there are 1000 pulses counted in a pulse waveform.
