Two projectiles are launched at the same speed. Projectile #1 is launched with a velocity of 20 m/s at 30° above the horizontal. At which of the following angles listed below could projectile #2 be launched in order to have the same horizontal range as
projectile #1?

continuous conducting path for current, power supply

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
