≅ 10 
Answer:
In the air
Explanation:
light in air flows in a straight direction while in water it curves far away from the object(refraction)thus the bear in the air will catch the fish easily because in water the fish is refracted thus the bear may catch its refracted image thinking it is the fish
Answer:
<em>The less mass an object has, the </em><u>less</u><em> its gravitational [force.]</em>
Explanation:
Newton's Law of Gravity states that
. The two <em>m</em> values are the objects' masses, G is the gravitational constant, and <em>r</em> is the distance between the objects' centers. Notice how the mass values are in the fraction's <em>numerator</em>? That means <em>increasing</em> the mass of one or both objects <em>increases</em>
. That also implies the inverse; <em>decreasing</em> the mass of one or both objects <em>decreases</em>

I hope this helps you understand this concept a little more! Have yourself a fantastic day, 'kay?
Answer:
Part of that kinetic energy created by moving of particles in object is transformed to heat that can be measured by thermometer.
Explanation:
By moving object creates kinematic energy, that is true. In object itself small particles are moving and creating kinetic energy as well. Part of that kinetic energy created by moving of particles in object is transformed to heat that can be measured by thermometer.
Same thing is that when you run or exercise your body temperature is raising(because of moving ).
When you sit your body does not raise temperature.
