Answer:
N = 1.42 × 10⁴ cycles
Explanation:
Given that:
frequency f = 4.9 × 10¹⁴ Hz
Time = 2.9 × 10⁻¹¹ s
Speed = 2.3 × 10⁸ m/s
Recall that:
wavelength
Horizontal distance
Number of wavelengths
N = (4.9 × 10¹⁴ cycles/s) (2.9 × 10⁻¹¹ s)
N = 14210
N = 1.42 × 10⁴ cycles
Answer:
109ohm
Explanation:
Note: when resistors are connected in series
Rt = R1 + R2 + R3 = 23+81+5 = 109ohm
Answer:
The bird's speed immediately after swallowing is 6.17 m/s.
Explanation:
Given that,
Mass of the bird, m = 270 g = 0.27 kg
Initial speed of the bird, u = 5 m/s
Mass of the insect, m' = 11 g = 0.011 kg
Initial speed of the insect, u' = 35 m/s
We need to find the bird's speed immediately after swallowing. Let it is given by V. Using the conservation of momentum as :
So, the bird's speed immediately after swallowing is 6.17 m/s.
Answer:
The error in tapping is ±0.02828 ft.
Explanation:
Given that,
Distance = 200 ft
Standard deviation = ±0.04 ft
Length = 100 ft
We need to calculate the number of observation
Using formula of number of observation
Put the value into the formula
We need to calculate the error in tapping
Using formula of error
Put the value into the formula
Hence, The error in tapping is ±0.02828 ft.
