Answer:
8 minutes
Explanation:
Part of the question is missing. Complete question is:
<em>Simpson drives his car 144 km with an average velocity of 24 m/s toward the east. How much time would Simpson save by increasing his average velocity to 26m/s East?</em>
Solution:
First of all, we have to calculate the time it takes for Simpson to complete the drive moving at the initial velocity, 24 m/s. We can use the formula:
where
is the displacement
is the velocity
Substituting,
While driving at 26 m/s, the time taken will be
So, Simpson will save 8 minutes.
Answer:
Explanation:
Given,
Width of slit, W = 5.7 x 10⁻⁴ m
Distance between central bright fringe, L = 4 m
distance between central bright fringe and first dark fringe, y = 4 mm
Diffraction angle
Now.
m = 1
La longitud del faldón de la rampa es de 5.4 m.
La pendiente expresada en porcentaje sigue la siguiente ecuación:
(1)
Donde:
- y es la elevacion de la rampa (faldón)
- x es la longitud de la ramapa (20 m)
Sabemos que la pendiente es de 27%. Por lo tanto, usando la ecuación 1, despejamos y.
La longitud del faldón es 5.4 m

Answer:
All soft drinks contain water. When soft drink bottles are chilled in sub-zero temperatures, the water on account of its anomalous expansion expands. Thus, to provide space for expanding water, soft drink bottles are not completely filled as otherwise they will burst.

<h2><em>The Doppler effect is a change in the frequency of sound waves that occurs when the source of the sound waves is moving relative to a stationary listener. As the source of sound waves approaches a listener, the sound waves get closer together, increasing their frequency and the pitch of the sound.</em></h2><h2><em>HOP</em>E IT HELPS </h2><h2>THANK YOU </h2>
