Use this kinematics equation:
Vf = Vi + aΔt
Vf is the final velocity, Vi is the initial velocity, a is the acceleration, and Δt is the elapsed time.
Assign northward velocity/acceleration as positive and southward as negative. Given values:
Vi = 100km/h = 27.8m/s
a = -4m/s²
Δt = 6s
Plug in the values and solve for Vf:
Vf = 27.8 - 4(6)
Vf = 3.8m/s north
Answer:
The answer is D , none of the above
Explanation:
1600÷8=200s 1200÷90=13.33s 50÷15= 3.33s (1600+1200+50)/(200+13.33+3.33) = 13.15m/s
It increases efficiency. Hope this helps!!!
WHY HELLO THERE! THE PREFIX NANO MEANS ''1 BILLIONTH OF'' AND IS USED MOSTLY WHEN TALKING ABOUT THE METRIC SYSTEM. HOPE THIS HELPED!!!!!
Answer:
Its duration is 1.85*10⁻³ s or 1.85 ms
Explanation:
The intensity of electric current I is defined as the amount of electric charge Q (measured in Coulombs) that passes through a section of a conductor in each unit of time. The letter I is used to name the Intensity and its unit is the Ampere (A).
The intensity of electric current is expressed as:
where:
I: Intensity expressed in Amps (A)
Q: Electric charge expressed in Coulombs (C)
t: Time expressed in seconds (s)
Being:
Replacing:
Solving:
19500 A*t= 36 C
t= 1.85*10⁻³ s= 1.85 ms (being 1 s= 1,000 ms)
<u><em>Its duration is 1.85*10⁻³ s or 1.85 ms</em></u>
