Explanation:
potential energy = mass × gravity force × height
=20 × 10 × 25
= 5000 joules
0kg
If the gravitational pull is zero and I multiply by mass I get a zero
Answer:
the answer is 2 electrons
Explanation:
The oxygen atom has atomic number 8, therefore its electronic configuration is
1s² 2s² 2p⁴
the sublevel s has a capacity for 2 electrons so it is full
the sublevel p has capacity for 6 electrons, as in this atom it has only 4 electrons it needs two (2) more electrons to have its full capacity and to achieve maximum stability.
Consequently the answer is 2 electrons
9.19 seconds (2dp)
Given:
v = 50m/s
u = 0 m/s
a = 5.44 m/s
t = ?
Substitute values into the equation v = u + at
v = u + at
50 = 0 + 5.44 x t
t = 50/5.44
t = 9.19 seconds
Time is in seconds as the velocity and acceleration are in metres per second instead of kilometres per hour
Answer:
The answer to your question is below
Explanation:
Data
m = 3 kg
vo = 6 m/s
vf = -8 m/s
Process
a= Initial kinetic energy
Eko = (1/2)mv²
Eko = (1/2)(3)(6)²
Eko = 54 J
b) Final kinetic energy
Eko = (1/2)(3)(-8)²
Eko = 96 J
c) Initial momentum
pi = (3)(6)
pi = 18 kg m/s
d) Final momentum
pf = (3)(-8)
pf = -24 kg m/s
