You could do it in just a couple of seconds if you really try. Find a place that's close to the equator, then do it on a day close to March 21 or September 21, at 12:00 noon, when the air is really clear. Keep your eyes wide open and don't squint. Good luck ! I know you can do it !

How does eating food produced locally benefit the environment?
fomenos

Answer:

Eating food produce locally makes it where big trucks don't have to bring it to the restaurant  

Explanation:

When the big trucks drive it they release pollutants into the air so therefore when you get stuff produced locally you don't have the big trucks polluting the air. So therefore it is better for the environment.

An alien spaceship traveling at 0.600 c toward the Earth launches a landing craft. The landing craft travels in the same directi
Thepotemich [5.8K]

The distance to the Earth at the moment of the landing craft's launch as measured by the aliens is 0.16 light years.

To find the answer, we have to know about the Lorentz transformation.

<h3>What is the distance to the Earth at the moment of the landing craft's launch as measured by the aliens?</h3>

It is given that, an alien spaceship traveling at 0.600 c toward the Earth, in the same direction the landing craft travels with a speed of 0.800 c relative to the mother ship. We have to find the distance to the Earth at the moment of the landing craft's launch as measured by the aliens.

  • It is given that; the spaceship is 0.200 ly from the Earth when the landing craft is launched.
  • By Lorentz transformation equation, the value of the distance to the Earth at the moment of the landing craft's launch as measured by the aliens will be,

        L=L_0\sqrt{1-\frac{V^2}{c^2} } =0.2ly\sqrt{1-\frac{(0.6c)^2}{c^2} }=0.2ly\sqrt{1-0.36}=  0.16ly

Thus, we can conclude that, the distance to the Earth at the moment of the landing craft's launch as measured by the aliens is 0.16 light years.

The momentum of an object is not dependent on which one of the following quantitiesa) acceleration b) inertiac) massd) velocity
amm1812

Answer:

Inertia

Explanation:

We have to find that on which quantity the momentum of an object does not depend.

We know that  

Momentum of object=mv

Where m=Mass of object

v=Velocity of object

Momentum of object depends upon mass and velocity.

When velocity of object increases then momentum is also increases.

When the mass of object is increases then the momentum of object is also increases.

If mass decreases then the momentum of object decreases.

If velocity decreases then the momentum of object decreases.

Acceleration depends on velocity  because

Acceleration=\frac{dv}{dt}

Therefore, momentum is also depend upon the velocity.

Inertia is defined as the property of object that resist change in its  motion.

Therefore, momentum does not depend on Inertia of object.

Give 2 examples for Newton’s first law of motion.​<br><br>please answer this question!!!!!
Katyanochek1 [597]
This means it doesn't change its velocity and it doesn't have momentum. 3. Examples of Newton's 1st Law  If you slide a hockey puck on ice, eventually it will stop, because of friction on the ice. It will also stop if it hits something, like a player's stick or a goalpost.
