Answer: 5.4 kg
Explanation:"Recall that force is the result when we multiply the values of an object's mass and acceleration. Mathematically, we have
F = ma
where F is the force (in Newtons, N), m is the mass (in kilograms, kg), and a is the acceleration (in m/s²).
Since we know that the eagle was accelerating at 22.35 m/s² with a force of 120N, we can solve for the eagle's mass as shown below.
m = F/a
m = (120)/(22.35) ≈ 5.4 kg
Hence, the eagle has a mass of approximately 5.4 kg."
Answer:
The average distance between the Earth and the Sun is about 93 million miles. All of the planets, comets, and asteroids in the solar system orbit the Sun. The average distance between the Earth and the Sun is 92,955,807 miles.

The true statement is that the speed of the meteor is 7.8 Km/s.
<h3>What id the velocity?</h3>
The term velocity refers to the ratio of the change in the displacement to time. This definition applies strictly to rectilinear motion. In a case of a circular motion like the Ferris wheel in which the direction of the speed continues to change, we say that the velocity is changing because the direction is changing.
Now, the speed of the meteor was given to be 468 km/min. In order to obtain the speed in kilometer per second we have to divide the given value by 60. Thus the true statement is that the speed of the meteor is 7.8 Km/s.

Answer:
Heat of reaction or enthalpy of reaction (ΔH)
Explanation:
The heat of reaction or enthalpy of reaction (ΔH) is the amount of heat energy that the system must release or absorb so that the temperature remains constant throughout the chemical reaction process. In other words, the heat of reaction or enthalpy of reaction (ΔH) is the change in the enthalpy of a chemical reaction (the energy absorbed or released into it) that occurs at a constant pressure.
Then, this energy can be observed in the following way:
Every substance has a quantity of energy stored in its links. When the energy contained in the reagents is greater than that contained in the products, the reaction is exothermic because energy release occurs. When the energy contained in the reagents is less than that contained in the products, an endothermic reaction occurs because energy absorption occurs.
That energy contained in the substances is called enthalpy (H).
Then the enthalpy can be defined as the difference between the sum of the enthalpies of the products and the sum of the enthalpies of the reactants.
