Answer:
4.7 s
Explanation:
The complete question is presented in the attached image to this solution.
v(t) = 61 - 61e⁻⁰•²⁶ᵗ
At what time will v(t) = 43 m/s?
We just substitute 43 m/s into the equation for the velocity of the diver and solve for t.
43 = 61 - 61e⁻⁰•²⁶ᵗ
- 61e⁻⁰•²⁶ᵗ = 43 - 61 = -18
e⁻⁰•²⁶ᵗ = (18/61) = 0.2951
In e⁻⁰•²⁶ᵗ = In 0.2951 = -1.2205
-0.26t = -1.2205
t = (1.2205/0.26) = 4.694 s = 4.7 s to the nearest tenth.
Hope this Helps!!!
Answer:
42.5W
Explanation:
To solve this problem we must go back to the calculations of a weighted average based on the time elapsed thus,

We need to calculate the average power dissipated by the 800\Omega resistor.
Our values are given by:


Aplying the values to the equation we have:



Answer:
The direction is downwards. This answer to this question is found from the applicatikn of flemings right hand rule. This rule uses the thumb, index finger and the middle finger in the direction of current force and the magnetic field.
Explanation:
By the de Broglie wavelength equation, the speed of proton is <u>0.47 × </u>
<u> m/s</u>.
λ = h / mv
λ = wavelength, given = 8.29 fm
h = plank's constant, given = 6.626 × 
m = mass, given = 1.672 ×
kg
v = velocity
Now, v = h / mλ
Put the values in formula, v = h / mλ
v = 0.47 ×
m/s
Therefore, the speed of proton is<u> 0.47 × </u>
<u> m/s</u>.
