Answer:
Explanation:
Distance between ship and enemy ship
= 500 + 610
= 3110 m
Range of projectile
R = u² sin2θ / g
= (250x 250 sin 150) / 9.8
= 3188m
The projectile falls within a distance of 3188 - 3110 = 78 m from enemy ship
Height of mountain = 1800 m
We shall find the height of projectile when its horizontal displacement is 2500m
x = 2500 , y = ?
u = 2500 ,
y = x / cos θ - .5 g x² /u²cos² θ
9660 - 7315 m
= 2345 m
It is within 545 m from mountain peak .

</span>All clouds are made up of tiny ice crystals or small
water droplets that form together with a dust on the atmosphere.
Cirrus, cirrostratus and cirrocumulus are made up of ice crystals. It forms
when the water vapor goes condensation at high altitudes in where the pressure
on the atmosphere reaches the point from 600 mbar at 4000 meter above the sea
level up to 200mbar at 12 000m above sea level. These clouds form
thunderstorms, cyclones and contrails (a manmade cloud).</span>
