If there is a car on the moon, can it be observed with the current technology of human beings?

Not observable. First of all, the most powerful telescopes on Earth can only distinguish objects 200 meters from the surface of the moon.

Secondly, space telescopes cannot be observed, because the Moon is too close to the Earth, which means that its speed is too fast for space telescopes to focus on observations, and the moon's brightness is very high, which can damage the observation instruments.

For example, the Hubble telescope, an excellent space telescope, can only distinguish details up to 150 meters when looking at a celestial object as close as the moon in theory, but in fact it cannot be aimed at the moon at all, and if it is aimed at the moon, then the consequences will be fatal. Until now, there has not been a single Hubble photograph of the moon in the world**.

One of the reasons why the mystery of the American moon landing has never been conclusive, is also because humans cannot photograph the national flag and the lunar module left on the surface of the moon, otherwise, one ** is enough to silence the opposition.

It depends on where the observer is, if it is in the orbit of an artificial satellite near the earth, it may not be observed, it depends on the reflective effect of the car, if its reflective brightness is greater than or equal to the brightness of a flashlight bulb equipped with three dry batteries (generally not), it can be seen with the Hubble telescope;If in the orbit of the artificial satellite of the moon with satellites that provide data from Google Earth ** it will do.

If there are aliens, of course, they will investigate, track, and obtain information, but they are not marked in the definition.

The main purpose of the lunar rover is to complete scientific research and obtain information on behalf of people. Through the lunar rover, it can realize the exploration of geological structure, structure, terrain, etc., and can also place a ** instrument to record the moon's moonquake and the impact of asteroids on the moon, and finally understand the current situation and evolution of the moon. In order to achieve a soft landing and smoothly transport the vehicle to the moon, the support of the entire system is required.

It is not clear which is the most advanced, because the current telescopes have their own strengths in order to achieve special purposes, especially the telescopes sent to space are even more diverse, and from different angles, different conclusions can naturally be drawn. To be sure, some telescopes can see cars on the moon, and there is no problem with this.

f denotes resistance.

1) The electrical energy is consumed because of the work done by the resistance In the reverse view, the work done by the resistance is equal to the electrical energy e electricity = wf =

2) When v is maximum, f=f=k'mg’g'=g 6 = 5 3 (on the moon) m = 200kg (known) f = 100 3k'

p=1600w v(max)=12m s(known) p=fv gives f=400 3 n

400/3 n=100/3k' n

k'=3) Flat ground resistance to do work w1=k'mg's'= 920000J Power Consumption = PT = 80000J Climbing Energy Consumption W3 = 12000 (known).

The energy required e=w1+w2+w3=1012000j 1000000j so no.

Solution: (1) According to **, it can be known that the time of receiving the signal twice before and after is 10s, and the displacement of the detector movement when receiving the signal twice before and after is 20m, then v=

xt2010m/s＝2m/s

2) According to **, it can be known: a=-2m s2

The displacement of the movement is 32-2 3-12m=14m, the time of deceleration is 7s, if the command is executed, the displacement of the movement x=v0t+

12at2=-35m

According to **, it can be known that the displacement of the movement is 14m, so the order is not executed 3) If I am a staff member of the control center, I will immediately issue a deceleration order, which can be known from **; The movement must be stopped within 12m, according to 2ax=v2 v02:

a=424＝−

Answer: (1) The velocity of the detector when it moves at a uniform speed is 2m s;

2) After data analysis, the reducer did not execute the deceleration command;

3) If I am a staff member of the control center, I should immediately issue a deceleration order, and the acceleration is magnitude.

The order was not executed, 9:10:20.52 meters. At 9:10:30 was 32m, and she found that you could calculate the speed of 2 meters and seconds when you measured an object of the speed of the shield moving the chain.

If the command to decelerate is executed, the speed between 9:10:30 and 9:10:40 is less than 2 m seconds, or 2 m s, or a uniform linear motion is calculated. Therefore, it does not run the command.

At the speed of light, 30 kilometers give a command, and 1 second for receiving a command gets 1 point. Because it is moving at a uniform speed, it will advance to 2 meters in a muffled second 1 second = 2 meters, so it has a round obstacle of 10 meters.
