Answer:
last option is the correct one
Answer:
d = 185.26 meters
Explanation:
It is given that,
Launching angle of the projectile, 
Initial speed of the projectile, u = 48 m/s
Let at distance d the projectile hits the ground from the launch point. It is equal to range of the projectile. Its formula is given by :

Substituting all the values in above formula. So, we get :

d = 185.26 meters
So, the distance between the launch point and the point where it hits is 185.26 meters. Hence, this is the required solution.
Sn is Tin which has 50 atomic number
it means it has 50 electrons in its outer shells
+2 shows its valency
plus sign comes when electrons are removed from an atom
so here 2 electrons are removed from Sn atom
remaining electrons are 50-2
48 electrons
Answer:
The correct option is;
3. layers of cotton lining the interior
Explanation:
In the procedure for making a solar oven it is essential place the inside portion of the carboard flap be made that the air made hot by the heat of the Sun does is not removed from the oven as convection current, and to provide insulation that limits heat loss by thermal radiation as well as conduction to cooler surfaces.
It slows down. The molecules/particles aren't as close together, resulting in slower movement.
