Answer:
work done is 470400 J
Explanation:
given data
long = 3 m
wide = 2 m
deep = 4 m
density = 1000 kg/m³
to find out
Find the amount of work in joules
solution
we know here volume = area × length
so
area = 0.5 ×base×height
area = 0.5 ×2×4
area = 4 m²
so volume = 4 × 3 = 12 m³
and
weight of water = volume ×density×g
weight = 12 × 1000 × 9.8
weight = 117600 N
so
work done = weight × height
work done = 117600× 4
work done = 470400 J
Answer:
The number of electron in the outermost shell of a particular atom determine how the reactivity of atoms to form chemical bonds with other atoms
Explanation:
This is because the number of atoms in the outer shell will determine if the atom has to gain or loose electrons for it to bond with other atoms
Hope this helps, and if it does mark as branliest answer thx
Answer:
D
Explanation:
<u>The correct answer would be option D.</u>
Gallium (Ga) , germanium (Ge) , selenium (Se)
, and arsenic (AS) all belong to the same group of elements referred to as the transition elements. The transition elements have partially-filled d orbital, a feature that confers some characteristic properties on the elements or their ions. These properties include:
- <em> variable oxidation state of </em>
- <em>formation of colored ions and compounds</em>
- <em>catalytic property</em>
- <em>paramagnetic compounds</em>
- <em>etc.</em>
Answer:
510 m
Explanation:
The arrow is fired upward, so the motion of the arrow is a free fall motion, therefore we can find the maximum height by using the suvat equation
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the displacement
Here we have:
v = 0 (at the point of maximum height, the velocity of the arrow is zero)
u = 100 m/s (initial velocity)
(acceleration of gravity, downward)
s = ? is the maximum height
Solving for s, we find the maximum height of the arrow:
