Answer:m=80 kg
Explanation:
Given
mass of Person
When Person Steps From boat onto shore boat moves away to 0.6 m/s away from shore
let v be the velocity of Person and m be the mass of boat
Conserving momentum
----1
When Person step on to boat, boat moves on to left 0.4 m/s towards left
---------2
using 1 and 2
therefore
Answer:
Explanation:
First, we will calculate the inductance of the solenoid by using the following formula:
where,
L = self-inductance of solenoid = ?
μ₀ = permeability of free space = 4π x 10⁻⁷ N/A²
A = Cross-sectional area = 30 cm² = 3 x 10⁻³ m²
N = No. of turns = 2000
l = length = 65 cm = 0.65 m
Therefore,
Now, we will use Faraday's law to calculate the rate of change of current:
Answer: I am pretty sure that you should pick radio waves.
Explanation: The scientist should use radio waves. I think this because you can use the radio waves to analyze the signals from outer space. This will work much better than anything there, to analyze it the best possible.
The best I could do.
