Answer:
54
Explanation:
d = vo*t + ½*g*t²
d = 3*3 + ½*10*3²
d = 9 + 45
d = 54 m
entonces el objeto tiene 54 m de desplazamiento
Answer:
β2= β1+10*f
Explanation:
comparing β2 and β1, it is said that β2 is increased by a factor of f.
for each factor of f, there is a 10*f dB increase.
therefore if the β1 is increases by an intensity of factor f
the new intensity would be β1+ 10*f
Needs are less than resources, and the population increases.
Answer:
B
Explanation:
The control is something that is meant to not be changed, the control is a comparison of the experimental.
Answer:
31,360J
Explanation:
Gravitation potential energy (gpe) is calculated from the formula mgh.
That implies, gpe = mgh
Therefore substituting the values of m and h as given in the question, knowing in mine that the acceleration due to gravity( g) is 9.8 N/kg, will give 31,360J
Never forget to put your SI units, because even if your answer is numerical correct, it will be incorrect because it represents no physical quantity.
