Answer:8.1 m
Explanation:
Given
ball is launched from height of 3 m
initial velocity
considering the ball is thrown vertically upward
Using
where,
u=initial velocity
v=final Velocity
a=acceleration
s=distance
At maximum height final velocity will be zero
Therefore maximum height w.r.t ground is
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:
Unbalanced
Explanation:
There is an acceleration. Look at the direction of the arrows.
It might slow down because it has to overcome friction
Answer:
Speed. I am speed.
Explanation:
The FitnessGram Pacer Test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start.
