Answer:
B
Explanation:
The object with the most thermal energy is the choice B. This is because from the given choices, it has the most mass and highest temperature of all the bricks.
Thermal energy is the sum total of the average kinetic energy within the system.
It is mathematically expressed as:
Quantity of energy = mass x specific heat x change in temperature
We see that the quantity of the thermal energy is directly proportional to mass and temperature changes.
I think it is D. Brownies are harder to bake than cupcakes. an example of an objective statement is why a company is hiring for that certain job. let me know if this is correct!

Answer:
Explanation:
A track 100m
The sprinter passes 12m mark in 1.8seconds
Let this be the initial point
d1 = 12m
t1 = 1.8seconds
And Passes the 56m mark in 6.7 seconds
Then, the second point is
d2 = 56m
t2 = 6.7 seconds
The sprinter velocity between this two position
Velocity is the rate of change of displacement
V = displacement / time taken
V = ∆x / ∆t
V = (x2 - x1) / (t2 - t1)
V = (56 - 12) / (6.7 - 1.8)
V = 44 / 4.9
V = 8.98 m/s
Then, the sprinter velocity between this two position is 8.98 m/s
Fusion occurs in the D. core of the Sun, where the pressure and temperature are very high.
This process happens in the very center of this star, which is known as the place where the temperature is the highest.
