Pavlova-9 [17]
The total money that will be present in the bank account, disregarding the percent rate of money increase is the sum of the initial deposit and the all the amounts deposited for m months, 25m. Thus, the answer should be,
                                    T = 10 + 25m

A sound wave has a frequency of 776 Hz in air and a wavelength of 0.52 m. What is the temperature of the air? Relate the speed o
OLEGan [10]

Answer:

142.7650889

Explanation:

I think the answer above is correct. So to find the velocity of the wave you can do: frequency*wavelength = velocity

in your case, the velocity is equal to 403.5m/s

so we know that the 403.52 is the total velocity of the wave

and the equation: velocity at 0 degrees Celsius * \sqrt{{T}/{273}} where T represents temperature in Kelvins = veloctity

so we set 403.52 = 327*\sqrt{{T}/{273}} and solve for T

T will then equal the degree in Kelvins

so to convert from Kelvins to degrees celsius you subtract 273 from the Kelvins value and you are left with the degrees in Celsius which equals 142.7650889 degrees Celsius

Sobre un cuerpo de 700 g de masa que se apoya en una mesa horizontal se aplica una fuerza de 5N en la dirección del plano. Calcu
kicyunya [14]

Answer:

(a) Ff = 3.95N

(b) Ff = 5N

Explanation:

(a) To find the friction force you use the second Newton law:

F=ma

But you take into account the applied force and the opposite friction force:

F_a-F_f=ma

you do Ff the subject of the formula and replace the values of the parameters:

F_f=F_a-ma=5N-(0.700kg)(1.5m/s^2)\\\\F_f=3.95N

(b) In the case of a motion with constant velocity you have that there is no acceleration. Hence:

F_a-F_f=0\\\\F_f=F_a\\\\F_f=5N

The experiments Galileo performed, such as rolling a ball down an inclined plane, are important because they
anyanavicka [17]

Galileo Galilei is one of the key figures in the history of Science, being the first to apply the experimental-mathematical scientific method. He carried out experiments and careful observations in kinematics (his studies on the trajectory of projectiles are famous) and dynamics (it should be noted his careful experiments with inclined planes), establishing the first law of Dynamics (which Newton will later collect and refine in his Principles); and in Astronomy, with which he could unequivocally support the heliocentric theory.

His experiments were addressed by methodologies that allowed him to precisely find his mathematical calculations and to verify theories he was developing over time. His manuscripts were key to disseminate the applied method and extrapolate them to other scientific areas.

Therefore the correct answer is C.
