Answer:
0.125Hz
Explanation:
The relationship between period and frequency is given by
where f is the period and T is the frequency.
Given that T = 8.00s
The period of a swinging object is the time it takes to make one complete oscillation, it is measured in seconds (s) while the frequency is the number of complete oscillations made per unit time and it is measured in Hertz (Hz). Period and frequency are inverse of each other.
Protons have a positive charge which is indicated by a + sign.
Hence, the answer is C.
Hi there!
We can begin by calculating the distance remaining after the reaction time.
Δd = vt
Calculate the distance traveled within this time:
Δd = (16)(.79) = 12.64 m
Subtract from the total distance:
150 - 12.64 = 137.66 m remaining
We can use the following equation to solve for the acceleration necessary:
vf² = vi² + 2ad, where vf = 0 since the train will have slowed down to rest.
Rearrange in terms of "a":
0 = vi² + 2ad
(-vi²) = 2ad
(-vi²)/2d = a
Plug in the given values:
(-(16²))/2(137.66) = a
-256/275.32 = -.9298 m/s²
Answer:
Explanation:
given data:
density of water \rho = 1 gm/cm^3 = 1000 kg/m^3
height of water = 20 cm =0.2 m
Pressure p = 1.01300*10^5 Pa
pressure at bottom
= 1.01300*10^5 - 1000*0.2*9.8
= 99340 Pa
h_[fluid} = 0.307m
Answer:
Scientific theories allow scientists to make predictions.
