Alguien me podria ayudar con esto pliz.. Ahora resuelva el siguiente ejercicio, tenga presente lo visto en clase y aprendido en

los puntos anteriores Un móvil parte del reposo, al llegar a los 4 segundos lleva una velocidad de 12m/s, al llegar a los 7 segundos mantiene esta velocidad, para después al llegar a 12 segundos disminuir a 7m/s su velocidad, y continuar con esta misma hasta llegar a 18seg, para que a los 20seg aumente su velocidad hasta 14m/s y luego bruscamente detenerse a los 27seg a. Halle la velocidad en cada intervalo b. Halle la aceleración en cada intervalo c. Halle la distancia recorrida en cada intervalo d. Grafique V vs t e. Grafique a vs t f. Grafique X vs t

Answer:

a.)1.)12m/s

2.)12m/s

3.)7m/s

4.)7m/s

5.)14m/s

6.)0m/s

b.)1.) 3m/s^2

2.)1.71m/s^2

3.).58m/s^2

4.).39m/s^2

5.).70m/s^2

6.)0

c.)1.)48m

2.)84m

3.)84m

4.)126m

5.)280m

6.)suma todos los metros mas 98m y obtendras la distancia en cual el carro se para

Explanation:

vinicial=0m/s

tiempo inicial=0s

Intervalo 1

v=12m/s

t=4s

aceleracion= vf-vi/t

=12-0/4

=12/4=3m/s^2

Intervalo 2

v=12m/s

t=7s

a=12/7

Intervalo 3

v=7m/s

t=12s

a=7/12

Intervalo 4

v=7m/s

t=18s

a=7/18

Intervalo 5

v=14m/s

t=20s

a=14/20

Intervalo 6

v=0m/s

t=27s

a=0/27

Name two things radio waves have in common with visible light
kondaur [170]
Radio waves and visible light, as we perceive it, are both part of the EM spectrum. The only difference between them in terms of our perception is that we don't have receptors to 'see' radio waves. That's where radio receivers come into the picture*, to convert radio waves into sound impulses that we can hear.

Write three nuclear equations to represent the nuclear decay sequence that begins with the alpha decay of u-235 followed by a be
vazorg [7]

Answer:

We know that in the decay process the sum of molecular number as well as molecular weight should be constant.

The following three reaction are as follows

1 .

Alpha decay  of parent nuclide

_{92}^{235}\textrm{U} \rightarrow _{90}^{231}\textrm{Th}+_{2}^{4}\textrm{alpha }

The molecular number of alpha particle is 2 and molecular weight is 4 g/mol.

2.

Beta decay of daughter nuclide

_{90}^{231}\textrm{Th}\rightarrow _{91}^{231}\textrm{Pa}+_{-1}^{0}\textrm{beta}+v

v is the neutrino emission,The charge on the beta particle is zero.

3.

Alpha decay

_{91}^{231}\textrm{Pa}\rightarrow_{89}^{227}\textrm{Pa}+_{2}^{4}\textrm{alpha}
