Answer:
El coeficiente de fricción entre el bloque y el piso es 0,64.
Explanation:
Podemos hallar el coeficiente de fricción usando la definición de trabajo:
En donde:
Kf es la energía cinética final =0
Ki es la energía cinética inicial
m: es la masa = 2 kg
v: es la velocidad = 5 m/s
Además el trabajo es el producto de la fuerza de rozamiento (Fr) por el desplazamiento (d), por lo que tenemos:
Por lo tanto, el coeficiente de fricción entre el bloque y el piso es 0,64.

Answer:
= Approximately 6
Explanation:
<u>What we need to know:</u>
1. Given that this is a parallel circuit, each pathway will receive the full voltage from the source. Therefore, each pathway will receive 17V.
2. The current (I) stays the same for all loads in series. Therefore, I2 and I3 are equal since they are connected in series.
3. Ohm's law states that Voltage = Current × Resistance (V=IR)(I=V/R)(R=V/I)
<u>1) Calculate the current for the path containing R2 and R3</u>
Because the current running through this path is A, then I2 is A.
<u>2) Use Ohm's Law by plugging in I2 and R2</u>
(approximate)
Therefore, V2 is approximately 6V.
I hope this helps!
Answer:
Kinase Enzyme
Explanation:
Kinase is an enzyme that catalyzes a biochemical reaction where it transfers phosphate groups from high-energy, phosphate-donating molecules to specific substrates. This process is known as phosphorylation. During phosphorylation, the substrate gains a phosphate group and the high-energy ATP molecule donates a phosphate group.
Kinases belong to the enzyme family of phosphotransferases. Kinases are different from phosphorylases, as the latter catalyzes the reaction where inorganic phosphate is added to the substrate. Therefore, kinases are essential enzyme in human physiology.
