You have 50L of water, it froze. So find its new volume. Density of water is 1000kg/m^3 or 1kg/L, density of ice is 920kg/m^3 or
ad-work [718]

Answer:

D (density) = Mass / Volume

V (ice) = Mass / Density = 50000 g / .92 kg / L

V = 50 kg / .92 kg / L  

1 Liter of water weighs 1 kilogram = 50 L weighs 50000 g

V = 54.3 L     the mass does not change upon the change of phase (freezing)

Solve the problem. Unless stated otherwise, assume that the projectile flight is ideal, that the launch angle is measured from t
kirill115 [55]

Answer:

d = 185.26 meters

Explanation:

It is given that,

Launching angle of the projectile, \theta=26^{\circ}

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 :

d=\dfrac{u^2\ sin2\theta}{g}

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

d=\dfrac{(48)^2\ sin2(26)}{9.8}

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.

HI PLEASE HELP!
butalik [34]

Answer:

Chemical reactions occur slower at lower temperatures and faster at higher temperatures. When you put a glow stick in cold water, the chemical reaction slows down but will last for a longer period of time. When you put a glow stick in hot water, the reaction speeds up but will be over quicker.

Explanation:

(self-explanatory)
