Question

   v grows as well
   v stays constant
   v grows but then stops growing
   v oscillates

Equation 2: T = 2(L/g)1/2 (pendulum equation)

What would happen to the period of a pendulum if the strength of gravity were to increase?

   it would fluctuate
   it would lengthen (take more time)
   it would shorten (take less time)
   it would not change

What happens to the period of a pendulum if you double the length of the cord and make gravity only half as strong?

   it will become half as long
   it will quadruple
   it will double
   nothing, it will not change

p = gd (pressure change with depth in a fluid)

where p = pressure, = density, g = gravitational acceleration and d = depth.
Which of the following doesn’t matter concerning the pressure you feel in the water of a swimming pool?

   the density of the water
   the Earth's gravity
   the shape of the pool
   how deep under the surface you are

p = gd (pressure change with depth in a fluid)

…where p = pressure, = density, g = gravitational acceleration and d = depth.

   the pressure you experience will fluctuate
   you will experience no change in pressure
   you will experience a decrease in pressure
   you will experience an increase in pressure

p = gd (pressure change with depth in a fluid)

…where p = pressure, = density, g = gravitational acceleration and d = depth.

   it doubles
   it triples
   it stays the same
   it increases by a factor of 12

: F = Gm1m2/d2 (Newton’s Law of Gravity, the gravitational attraction between two objects)

…where G is the gravitational constant, m1 is one of the masses, m2 is the other mass and d is the distance between the centers of the two objects.

   the distance between the centers of the objects
   the mass of one of the objects
   the mass of the other object
   the color of the objects

Explanation / Answer

1)


as t grows

v grows as well <-asnwer

Equation 2: T = 2(L/g)^1/2 (pendulum equation)

    it would shorten (take less time)


3)

T2/T1 = sqrt(L2*g1/L1*g2)


L2 = 2l1

g2 = g1/2


T2/T1 = sqrt(2L1*g1/L1*2*g1)

T2 / T1 = sqrt(4) = 2


T2 =2T1

it will double

4)

p = gd (pressure change with depth in a fluid)

where p = pressure, = density, g = gravitational acceleration and d = depth.

    the shape of the pool

5)

p = gd (pressure change with depth in a fluid)

…where p = pressure, = density, g = gravitational acceleration and d = depth.

    you will experience an increase in pressure


6)


p = gd (pressure change with depth in a fluid)

…where p = pressure, = density, g = gravitational acceleration and d = depth.


p2/p1 = 2g2d2/1g1d1


d1 = 1m

d2 = 2m


2 = 31


g2 = 2g1


p2/p1 = 3*2*2 = 12

   it increases by a factor of 12
