Answer: 2.43 s
Explanation:
Initial velocity is
Final velocity
Average acceleration is
Average acceleration is change in velocity in the given amount of time
Thus, 2.43 s is required to acquire that average acceleration with 23 m/s velocity .
Answer:
The Normal Force is zero.
Explanation:
The reason for the normal for to be zero is because no matter if the is a form of contact at the top, the is no force applied by the cart to loop-de-loop, and so vice versa.
If the cart was on the bottom, then the normal force would be equal to the weight of the cart, which would be te force the cart would be applying to the loo-de-loop, and therefore by newton's third law, the loop-de-loop would apply an equal force to the cart, which we would say is the normal force.
Answer:
40 metros en 10 segundos.
Explicación:
Una grúa está levantando una caja de 1000 kg atada a una cadena y la caja, que inicialmente está en reposo, aumenta su velocidad en 4 m / s por segundo, por lo que si la región de colocación está a 40 metros de distancia, la grúa tarda 10 segundos en completar el proceso. tarea de movimiento y colocación de la caja. La grúa se utiliza para levantar y mover cargas pesadas, máquinas, materiales y mercancías para diferentes propósitos. Entonces el trabajo realizado por la grúa depende de la velocidad y la distancia de colocación.
Answer:
f = c / y where y is the wavelength
f1 = 3 *10E8 m/s / .001 m = 3 * 10E11 / s
f2 = 3 * 10E8 m/s / 1 m = 3 * 10E8 / s
Answer:
The set of frequencies of the electromagnetic Waves emitted by the atoms of an element is called emission spectrum.
