Burka [1]
An example of an environmental issue is the acid rain in Germany. The acid rain is caused by pollution. Pollution that was caused by car putting harmful gases into the air is the main reason that there is acid rain in Germany. This is a problem because the acid rain is destroying Germany’s forests. Hope this helped!

A book is pushed with an initial horizontal velocity of 5.0 meters per second off the top of a desk. What is the initial vertica
PSYCHO15rus [73]

Answer:

The Initial vertical velocity is zero

Explanation:

Given that,

A book is pushed with an initial horizontal velocity, Vx = 5 m/s

According to projectile motion, the horizontal component of velocity i.e., in X-axis remains the same though out its path.

The vertical velocity varies i.e., the velocity towards the Y- axis.

The velocity of the falling book in its trajectory is the resultant velocity. Due to the action of gravity, it keeps on increasing with time.

The resultant velocity is given by relation

                V_{R} = \sqrt{{V_{x}^{2}} +[ {gt}]^{2} }

where

               gt = Vy - vertical velocity

                        g - acceleration due to gravity

                        t - time

Since, the initial horizontal velocity at that instant is equal to the resultant velocity.

                  Vx  = 5 m/s

                  V_{R}  = 5   m/s

So, on substituting in the above equation          

                         Vy = 0  m/s

Therefore, the initial vertical velocity is equal to zero

What is the Potential energy of a magnetic generator
sergiy2304 [10]

Well potential energy is energy possessed by an object of by the position it's in. For example when you hold back a bow and arrow, but before you shoot it you are containing energy by holding the arrow back. So when you start the magnetic generator (pull or turn to start it) before using it for its purpose that is potential energy. I hope this helps.

Irina18 [472]
<span>Young modulus E = stress/strain where E is the elastic modulus. We seek to calculate the the strain. But we would have to get the stress first. Tensile stress = Force/Area. Force = 20100N. And the Area = 9.54* 13.9 = 132.606Nm^2. Strain = stress/E.where E = 79. Hence we have 132.606/79 = 1.67</span>
