The answers are:

bulb, motor, buzzer and swtich.

As seen in the picture attached,

The electric current leaves the battery passes through the bulb. It then travels through the motor, next through the buzzer and finally passes through the switch before returning to the battery.

Pedro e Maria saíram para passear de carro. Eles partiram de São Paulo às 10 h em direção à Braúna, localizada a 500 km da capit

Salsk061 [2.6K]

Answer:

This can be translated to:

"P edro and Maria went for a drive. They left São Paulo at 10 am towards Braúna, located 500 km from the capital. As the journey was long, they made two 15-minute stops for gas and also spent 45 minutes for lunch. When arriving at the final destination, Maria looked at the clock and saw that it was 6 pm. What is the average speed of the trip?"

Ok, the first thing we know is, that for the average speed we can write:

Speed = Distance/time.

First, we know that Distance = 500km.

And for the time we have two possiblities:

The total average speed will decrease because they were stopped a total of:

15min + 15min + 45min = 75min = 1.25 hours

Then if the travel starts at 10am, and ends at 6 pm, the total time that has passed is:

6pm = 18hs

6pm - 10am = 18 - 10 = 8hs

Then the average speed will be:

Speed = 500km/8h = 62.5 km/h.

Now, if we considerate the average speed only when they are moving, the total time that they are moving is:

Total time in travel - time that they where stopped

8h - 1.25h = 6.75h

Then the average speed would be:

Speed = 500km/6.75h = 74.1 km/h

The question is asking how many moons Venus, the planet, has and the answer is 0 -Venus doesn't have any moons. Another planet that doesn't have any moons is Mercury. Earth has one moon and Mars has two moons. Jupiter has 4 moons and the most impressive is Saturn, with its 53 confirmed moons (as claimed by Nasa)!

Strictly speaking, as more and more skyscrapers are built on the surface of the Earth, does the day tend to become longer or sho

sveticcg [70]

Answer:

Assume that the planet has a defined angular momentum (this is not true due to tidal friction). So if mass is farther away from the center of mass it will have more angular momentum, and if mass is near you will have more angular momentum.

If the mass is similar to the center of mass and slower if the mass is farther from the center of mass, an object will spin faster to combat this. Building skyscraper will also slow down the earth and dropping leaves will raise the angular velocity.

A great example of this is with figure skaters, when they want to spin faster they tuck themselves in tightly, bringing more mass close to the center of mass which increases angular velocity there.
