Answer:
1650 feet
Explanation:
You multiply 55 times 3.3 and get an answer of 165. This mean that the person is falling 165 feet every second. Multiply 165 times 10 and get 1650 feet in ten seconds.
Answer:
refractors and reflectors
Explanation:
Answer:
B's acceleration is half that of A
Explanation:
The force equation is;
Force = mass × acceleration
According to Newton's second law of motion, which explains the relationship between acceleration and mass of an object, an inverse relationship exists between the mass and the acceleration. For the same amount of force, an increase in mass (m) means a constant decrease in acceleration (a) of the object. In other words, if the mass of an object increases by two times, the acceleration will decrease by two times.
In this case involving objects A and B which has the same amount of force applied, object B has TWICE the mass of A. Using Newton's second law, this means that object B's ACCELERATION WILL BE HALF OF THAT OF OBJECT A.
Answer:
-241.826 kJ·mol⁻¹; -146.9 J·K⁻¹mol⁻¹; 664.6 J·K⁻¹mol⁻¹; spontaneous
Explanation:
½O₂(g) + H₂(g) ⟶ H₂O(g)
ΔHf°/kJ·mol⁻¹: 0 0 -241.826
S°/J·K⁻¹mol⁻¹: 205.0 130.6 188.7
1. ΔᵣH
ΔᵣH = products -reactants = -241.826 -(0 + 0) = -241.826 kJ·mol⁻¹
2. ΔᵣS
ΔᵣS = products - reactants = 188.7 - (205.0 + 130.6) = 188.7 - 335.6 = -146.9 J·K⁻¹mol⁻¹
3. ΔS(univ)
4. Spontaneity
ΔG is negative, so the reaction is spontaneous.
Answer:
Distancia = 925 metros.
Explanation:
Dados los siguientes datos;
Tiempo = 50 segundos
Velocidad = 18.5 m/s
Para encontrar la distancia recorrida;
Matemáticamente, la distancia viene dada por la fórmula;
Sustituyendo en la fórmula, tenemos;
Distancia = 925 m.
Por tanto, el cuerpo recorrió una distancia de 925 metros.
