Answer:

Range will be 5707.364 m      

Explanation:

We have given initial velocity of projectile u = 355 m/sec

Angle of projection = 68.4°

Acceleration due to gravity g=9.81m/sec^2

Horizontal range is given by R=\frac{u^2sin2\Theta }{g}=\frac{355^2sin(2\times 68.4^{\circ})}{9.81}=8794.09m

It is given that range is shorten by 35.1%

So range will be 8794.09-(8794.09\times \frac{35.1}{100})=5707.364m

If we use 1 millimeter to represent 1 light-year, how large in diameter is the Milky Way Galaxy?
storchak [24]

Answer:

d.100 meters

Explanation:

The diameter of the Milky Way Galaxy is approximately 100,000 light years.

Here we are using 1 millimiter (1 mm) to represent 1 light-year (1 ly). So, we can set the following proportion:

1 mm : 1 ly = x : 100,000 ly

and by finding x, we find the diameter of the Milky Way Galaxy in the scale used:

x=\frac{(1mm )(100,000 ly)}{1 ly}=100,000 mm = 100 m

so the correct answer is

d. 100 meters
