I think it #3(not Sure) I think Its because of their long wavelengths that tsunamis behave as shallow-water waves.

Gravitational force is determined by which of the following

hram777 [196]

Gravitational force is determined by mass

Answer: Option B

Explanation:

According to Universal law of gravity, the gravitational force is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between the objects.

$F=G \times \frac{m_{1} \times m_{2}}{r^{2}}$

Where,

G – gravitational constant = $\text { 6. } 67 \times 10^{-11} \mathrm{Nm}^{2} / \mathrm{kg}^{2}$

$\boldsymbol{m}_{1}, \boldsymbol{m}_{2}$ = masses of two objects

r – distance between the objects

So, as per this law, the gravitational force is found by mass.

Un alumno menciona que al abrir la ventana de su casa sintió cómo el frío ingresaba a su cuerpo. Menciona cuál es la verdadera r

stepan [7]

Answer:

My believe the answer is

A.) or B.)

Explanation:

Here is why I think A is the answer.

If we use the process of elimination, it would look like this,

a) Porque el aire tiene una temperatura menor que la de su cuerpo; por eso se propaga más rápido.

This makes sense because we all know in winter the weather is very cold and freezing.

b) Porque la temperatura de su cuerpo, siente el aire frio que entra por la ventana.

I feel like this answer is the question, but it could also be an answer, sorry, I'm a little uncertain.

c) Porque el calor de su cuerpo se propaga al medio ambiente, al ser la temperatura del niño mayor que la del aire exterior.

This answer has nothing to do with the question, plus it is very false, our body heat is not enough to overcome the very cold temperature from outside.

d) Porque la temperatura del aire es igual a la temperatura del cuerpo.

This is false because again our body heat is not even compared to the freezing cold temperatures from the winter.
