Answer:
12.45kgm/s
Explanation:
1.27kg x 9.8m/s = 12.446kgm/s
The sum of decimal point is 3 and the unit kg multiplies m divided by s
The Sun is 864,400 miles across. its about 109 times the diameter of Earth<span>. so the volume is about 109 times the volume of the earth.</span>
Explanation:
Cells are divided by the reproductive means in unicellular organisms; whereas in multicellular organism they are the means for tissue development and maintenance in multicellular organisms. In adults, tissue renewal rather than development is the most common cell division in which several forms of cells are constantly replaced.
Answer:68m/s
Explanation:
Frequency=17Hz
Wavelength=4metre
Wave speed=frequency x wavelength
Wave speed =17 x 4
Wave speed =68m/s
Answer:
Eje x
fr- F = m a
eje y
N-W =0
Explanation:
Para este ejercicio, debemos usar la segunda ley de Newton, donde se necesita fija un sistema de referencia el mas usado es un sistema horizontal y vertical para los ejes x e y
en el adjunto puede ver el diagrama de cuerpo libre correcto,
las fuerza son
Eje x
fr- F = m a
eje y
N-W =0
la ecuacion para la fuerza de roce es
fr = my N
