Answer:
Explanation:
Scientific notation is very useful for very large and small quantities, it is based on placing an integer and respecting the decimal figures multiplied by a factor so that the measurement is not altered.
in the example of this exercise we must run the decimal point
1000 = 1,000 103³
TRASLATE
La notación científica es muy útil para magnitudes muy grandes y pequeñas, se basa en colocar un entero y el respeto las cifras en decimales multiplicado por un factor para que no se altere la medida.
en el ejemplo de este ejercicio debemos corre la punto decimal
1000 = 1,000 10³
Answer:
a) 
V.m , into the page
b) 
V, counterclockwise
Explanation:
a) 
At t = 2.90, I = 3.62 + 1.49 * (2.90)^2 = 16.15 A
V.m
Direction is into the page.
b) 
Direction is counterclockwise.
By the work-energy theorem, the total work done on the car is equal to the change in its kinetic energy:
<em>W</em> = ∆<em>K</em>
<em>W</em> = 1/2 (0.34 kg) (22.9 m/s)² - 1/2 (0.34 kg) (6.5 m/s)²
<em>W</em> ≈ 82 J
