cant see to find the answer sorry :( i tried :( good luck !! youll do great <333
Explanation:
Answer:
at the highest point the velocity and acceleration are perpendicular but when projectile starts to move are said to be parallel to one another
Explanation:
the clear explanation is shown above.
Just a guess without asking Google, that without the sun's gravity holding us in orbit, we would end up drifting whatever direction we were headed as it disappeared?
When light is passing from a denser medium to a lighter medium ( for example: from water to air)
<span> When the angle of refraction is greater than the critical angle( angle of incidence when the angle of refraction is perpendicular to the normal) of the denser medium.</span>
Answer:
7066kg/m³
Explanation:
The forces in these cases (air and water) are: Fa =mg =ρbVg Fw =(ρb −ρw)Vg where ρw = 1000 kg/m3 is density of water and ρb is density of the block and V is its density. We can find it from this two equations:
Fa /Fw = ρb / (ρb −ρw) ρb = ρw (Fa /Fa −Fw) =1000·(1* 21.2 /21.2 − 18.2)
= 7066kg/m³
