How much tension must a rope withstand if it is used to accelerate a 6526 kg car vertically upwards at 8.9 m/s^2?
ExtremeBDS [4]

Answer:

The value is T =  122036.2 \  N

Explanation:

From the question we are told that

     The mass of the car is  m  = 6526 \  kg

      The acceleration  is  a=  8.9 \  m/s^2

Generally the net force applied on the rope is mathematically represented as

          F_{net}   =  T -  W

Here W is the weight of the car which is evaluated as

         W =  m * g

=>      W =  6526  * 9.8

=>       W =  63954.8 \  N

Generally the net force can also be mathematically represented as

       F =  m * a

So

        m * a  =  T  -  63954.8

=>     6526  *  8.9 =  T  -  63954.8

=>      T =  122036.2 \  N

What are gamma rays and what are its uses??<br>​
sukhopar [10]

"Gamma rays" is the name that we call the shortest of all electromagnetic waves.  They're shorter than radio waves, microwaves, infrared waves, heat waves, visible light waves, ultraviolet waves, and X-rays.  They extend all the way down to waves that are as short as the distance across an atom.

Being so short, they carry lots of energy.  They can penetrate many materials, and they can damage living cells and DNA.  They're dangerous.

The sun puts out a lot of gamma radiation.  The atmosphere (air) filters out a lot of it, otherwise there couldn't even be any life on Earth.  

As soon as astronauts fly out of the atmosphere, they need a lot of shielding from gamma rays.

You know the precautions we take when we're around X-rays.  The same precautions apply around gamma rays, only a lot more so.

It's only in the past several years that we've learned how to MAKE gamma rays without blowing things up.  Also, how to control them, and how to use them for medical and industrial applications.
