Answer for number 1.   Weight is the force of gravity. It acts in a downward direction—toward the center of the Earth.

Lift is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences...

Thrust is the force that propels a flying machine in the direction of motion. Engines produce thrust.

2. For an airplane to takeoff, thrust must be greater than drag and lift must be greater than weight. To maintain level flight, lift must equal weight and thrust must equal drag. For landing, thrust must be less than drag, and lift must be less than weight.

3.When the forward forces are bigger than the opposing forces, you speed up (accelerate). As you go faster, the force of air resistance pushing back on you increases. Eventually, the forces become balanced (the forward forces are the same size as the opposing forces). Once the forces become balanced, your speed stays the same.

4.Every object on Earth has weight, a product of both gravity and mass. A Boeing 747-8 passenger airliner, for instance, has a maximum takeoff weight of 487.5 tons (442 metric tons), the force with which the weighty plane is drawn toward the Earth.

Which event would be impossible to explain by using John Dalton’s model of the atom?
Dvinal [7]
<span>Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass. Dalton also stated that all compounds were composed of combinations of these atoms in defined ratios. He postulated that chemical reactions resulted in the rearrangement of the reacting atom.

The decomposition of ammonia to nitrogen and hydrogen on a tungsten filament at 800°C is independent of the concentration of amm
finlep [7]

Answer:

Order zero

Explanation:

Let's consider the decomposition of ammonia to nitrogen and hydrogen on a tungsten filament at 800°C.

2 NH₃(g) → N₂(g) + 3 H₂(g)

The generic rate law is:

rate = k × [NH₃]ⁿ

where,

rate: reaction rate

k: rate constant

n: reaction order

When n = 0, we get:

rate = k × [NH₃]⁰ = k

As we can see, when the reaction order with respect to ammonia is zero, the reaction rate is independent of the concentration of ammonia.

Calculate the enthalpy for the following reaction. During the reaction, the temperature changes from 42.5 C to 37 C. The specifi
Dahasolnce [82]

Answer:

q = 0.810 Kj/mol

Its an endothermic reaction

Explanation:

Enthalpy can be evaluated by using following formula -

q = m * c* \delta T

where

q is the enthalpy or change in internal energy

m is the mass in kg

c is the specific heat

and \delta T is the change in temperature

Mass of HCl is equal to 36.46 g/mol

or

Mass of HCl is equal to 0.03646  Kg/mol

Substituting the given values in above equation, we get-

q = 0.03646 * 4.04 * (42.5 - 37)\\q = 0.03646 * 4.04 * 5.5 \\

q = 0.810 Kj/mol

Enthalpy is positive thus it is an endothermic reaction
