Based on the data provided, the thermal energies at the given time intervals are as follows:
- At time t = 0.0 secs; thermal energy = 0.0 J
- At time, t = 0.8 secs; thermal energy = 0.0 J
- At time, t = 2.0 secs; thermal energy = 3.9 J
- At time, t = 2.8 secs; thermal energy = 6.7 J
<h3>What is the law of conservation of energy?</h3>
The law of conservation of energy states that the total energy in an isolated system is conserved.
For a ball undergoing energy conversion between kinetic and potential energy, the sum of the energy remains constant.
Any reduction in total energy is due to conversion of some energy to thermal energy.
- Sum of energy: Kinetic + potential + thermal = 15.2 J
- Thermal energy = 15.2 - (PE + KE)
At time t = 0.0 secs
Thermal energy = 15.2 - (15.2 + 0.0)
Thermal energy = 0.0 J
At time, t = 0.8 secs
Thermal energy = 15.2 - (4.7 + 10.5)
Thermal energy = 0.0 J
At time, t = 2.0 secs
Thermal energy = 15.2 - (7.4 + 3.9)
Thermal energy = 3.9 J
At time, t = 2.8 secs
Thermal energy = 15.2 - (8.5 + 0.0)
Thermal energy = 6.7 J
Therefore, the thermal energies at the given time intervals are as follows:
- At time t = 0.0 secs; thermal energy = 0.0 J
- At time, t = 0.8 secs; thermal energy = 0.0 J
- At time, t = 2.0 secs; thermal energy = 3.9 J
- At time, t = 2.8 secs; thermal energy = 6.7 J

When white light passes through a prism, violet is the color that is refracted the most.
X - Xo = 0.5(Vo +V)t
Xo cancels because it is 0 (she is at rest)
17 = 0.5(0+V)3.8
17 = 1.9V
Final velocity is 8.94737 m/s
Answer:
Explanation:
B- The red horse's average speed was greater than the black horse's average speed.
Red average speed = 1/120 = 0.00833 mi/s
Black average speed = 1/150 = 0.00667 mi/s
we only know about average speed based on the information given. Either horse could have had higher or lower, even negative, instantaneous speed during some phase of the race.
In a person's forties, they are in the middle of stagnation vs. identity, so they are having an identity crisis.
