Answer:
Toothpaste
Explanation:
When red litmus paper turns blue, it's a clear indicator that the solution or item where it was put is basic. The most common household item which is known to be basic is toothpaste. Experimental studies show that when you put red litmus paper into toothpaste solution, it turns blue.
Answer:
See the explanation below
Explanation:
There are many factors that determine the affordability of a planet, than its distance from the sun. It is clear that the solar radiation received by humans cannot be greater or less than certain values recommended by scientists.
However this planet may have a stronger magnetic field that diverts in large quantities the dangerous radiation that can reach Kepler-186f, in the same way the star of this planet may have less intense radiation than our sun.
These factors can be seen in an easier way by investigating the properties of the planet Kepler-186f which must be different from the planet Earth.
When stopped, the velocity of the van is 0 m/s.
We can use the formula <em>
=
+</em> <em>at</em>, where <em>a </em>is acceleration.
0 m/s = 11.5 m/s + (3.5 s)<em>a</em>
<em>-</em>11.5 = 3.5a
<em>a ≈ </em>-3.28571429 m/s^2
Round it however you need.
The heat transfer that we'll have will be:
- At first, the metal bar will emanate heat through radiation, to the atmosphere, and to the second metal, through conduction.
- Because of this, the second bar will start to increase it's temperature, up to the fusion point, spending the energy received on the fusion, and also radiating heat to the atmosphere. It won't emit heat in any other form, since heat transmission can happen only from a hot body to a cooler one, and the only things in contact are the two bars.
Explanation:
because his lower body is in inertia of motion.
