Answer:

c. have an excess number of neutrons

Explanation:

A radioactive isotope is defined as any species of the same chemical element with <em>unstable nuclei that emit radiation (alpha, beta, gamma) in order to dissipate its excess energy.</em>

I hope you find this information useful and interesting! Good luck!

9. Una jeringa contiene cloro gaseoso, que ocupa un volumen de 95 mL a una presión de 0,96 atm. ¿Qué presión debemos ejercer en
masha68 [24]

Answer:

2.61 atm

Ley de Boyle

Explanation:

P_1 = Presión inicial = 0.96 atm

P_2 = Presión final

V_1 = Volumen inicial = 95 mL

V_2 = Volumen final = 35 mL

En este problema usaremos la ley de Boyle.

\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}\\\Rightarrow P_2=\dfrac{P_1V_1}{V_2}\\\Rightarrow P_2=\dfrac{0.96\times 95}{35}\\\Rightarrow P_1=2.61\ \text{atm}

La presión ejercida sobre el émbolo para reducir su volumen es de 2.61 atm.

In what speed does an object fall, if after 10 seconds it hits the surface of Earth?​
Maru [420]

Answer:

98m/s

Explanation:

Given parameters:

Time  = 10s

Unknown:

Final speed  = ?

Solution:

To solve this problem, we use the expression below;

          v  = u + gt

v is the final velocity

u is the initial velocity  = 0m/s

g is the acceleration due to gravity  = 9.8m/s²

t is the time

   so;

         v = 0 + 9.8 x 10  = 98m/s

What type of electromagnetic radiation was used to make this picture?
goldenfox [79]

Answer:

Hey there

as you can see in the image, you only see the bones of the hand. not the skin or muscles. That is because only bones absorb X-rays while skin and other tissue let them pass-through for the most part. So your answer is Xrays.

A 3kg box has 45J of gravitational potential energy, how high is it off the ground?
frez [133]

Answer:

1.53m

Explanation:

Given parameters:

Mass of box  = 3kg

Gravitational potential energy  = 45J

Unknown

Height of the box  = ?

Solution:

To solve this problem;

 Gravitational potential energy = mgh

m is the mass

g is the acceleration due to gravity

h is the height

            45  = 3 x 9.8 x h

            h  = 1.53m
