Answer:
5m/s
Explanation:
p=mv, or momentum (p) is equal to mass (m) times velocity (v).
so:
m=5Kg
p=25Kgm/s
v=p÷m
v=25÷5
v=5m/s
hoped this helped :)
The energy-level change occurs as the atom is absorbs a 2.03-eV photon.
<h3>
Energy change of the mercury atom</h3>
The energy change of the mercury atom is calculated as follows;
Energy emitted by a photon when it falls from level b to energy level e is calculated as follows;
ΔE = -3.71 eV - (-5.74 eV)
ΔE = -3.71 eV + 5.74 eV
ΔE = 2.03 eV
When electron jumps from lower energy level to higher energy level, energy is absorbed, thus, the energy-level change occurs as the atom is absorbs a 2.03-eV photon.

Answer:
Yes
Explanation:
Tube worms are living creatures.
From the calculation, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude
VELOCITY AND ACCELERATION
The rate of change of displacement is called Velocity. While acceleration is the rate of change of velocity.
Given that a race Car A accelerates on a straight track from 0 to 100 kilometers/second in 6 seconds.
Since acceleration =
a = 1000(100 - 0)/6
a = 100000/6
a = 16666.67 m/
And race Car B accelerates on a straight track from 0 to 100 kilometers/second in 5 seconds.
acceleration =
a = 1000(100 - 0)/5
a = 100000/5
a = 20000 m/
From the calculation above, we can conclude that both race car A and B have the same magnitude of velocity but accelerate at different magnitude.
Race car A accelerates at 16666.67 m/, while race car B accelerates at 20000 m/
