Answer:
The force becomes 16 times what it is now.
Explanation:
The formula for gravitational force is
F = G * m1 * m2 / r^2
When you do what you have described, you are setting a stage that not even the USS Enterprise (Star Trek) can get out of. The increase is huge.
If you double m1 and m2 and don't do anything to r, you've already increased the force by 4 times. (2m1 * 2m2 = 4 * m1 * m2)
But you are not finished. If you 1/2 the distance, you are again increasing the Force by 4 times. 1 / (2r) ^2 = 1/ 4* r^2
Because this is in the denominator, the 1/4 is going to flip to the numerator.
So the total increase is going to be 4 * (4 * m1 * m2) = 16 * m1 * m2.
Think about what that means. If you were out golfing, your drives would be roughly 1/16 times as far as they are now. Also you would be lugging around 16 times your weight around the golf course. My feeling is that you would never finish 5 holes at that rate.
Answer: Manipulating a constraint at any given time may produce a __functional ________ change in movement. However, in motor development, we are most concerned with changes in movements over time, particularly ones that become more __permanent __________.
Explanation:
Functional movements focuses on real-world situational biomechanics. They usually involve multi-planar, multi-joint movements which place demand on the body's core musculature and innervation.
Motor development focuses on a child's bones, muscles and ability to move around the environs. Motor development can be divided into two sections: gross motor development and fine motor development.
Answer:
223.61 km
Explanation:
Speed of car traveling south = 100 km/h
Speed of car traveling west = 50 km/h
Time each car travels = 2 hours
Distance = Speed×Time
Distance covered by car traveling south = 100×2 = 200 km
Distance covered by car traveling west = 50×2 = 100 km
Consider the distance covered by car traveling south as the base of a triangle and the distance covered by car traveling west as the height of a triangle
Distance between them after 2 hours would be the hypotenuse of the triangle
Pythagoras theorem
Hypotenuse = √(Base²+Height²)
⇒Hypotenuse = √(200²+100²)
⇒Hypotenuse = 223.61 km
So, they are 223.61 km apart two hours later.
Answer:
Increases
Explanation:
This is because if there are more gas particles available within a given area, the greater the air density. Therefore, the greater the air density, there will be more gas particles per unit volume. Which indicate that there are more air particles bombarding with a surface. Therefore, the air pressure increases as the air density increases and visa versa.
