Answer:
Explanation:
T = 2π
(T / 2π)² = L/g
g = 4π²L/T²
g = 4π²(0.75000)/(1.7357)²
g = 9.82814766...
g = 9.8281 m/s²
Answer:
3m
Explanation:
89.1 MHz means
89.1×10^6 cycles/second.
Electromagnetic radiation (including radio waves) travel at
3.0×10^8meters/second
Wavelength = Speed/Frequency
The wavelength of a
89.1MHz radio signal is
3.0×10^8/89.1x10^6
= 0.03x10^2
= 3meters
Answer:
i believe the answer is d.
Explanation:
its either d or its c. but based off of the fact the it is the only one with a positive charge and the one around it are negative then its most likely d.
Answer:
W = 1562.5 J
Explanation:
Path 1:
W₁ = F₁*d₁ = 385 N * 2.5 m = 962.5 J
Path 2:
W₂ = F₂*d₂ = 130 N * 10 m = 1300 J
Path 3:
W₃ = F₃*d₃ = (-350 N) * 2 m = - 700 J (opposite to the motion)
We get
W = W₁ + W₂ + W₃ = 962.5 J + 1300 J + (- 700 J) = 1562.5 J
Answer:
-2 C
Explanation:
charge of an electron = -
therefore charge of 1.25 x 
electrons = 
= -2 C
