he reason would be straightforward in case you have complete the test already. The bottles have a undeniable volume of air interior them.. you have often happening that gases do strengthen in case of heating.So, the air interior the bottle in sunlight expands.. often, in case you don't have an go out course for the air, it would desire to develop the stress interior the bottle or if is extra suitable than a undeniable decrease.It may blow up the bottle too. As u would desire to have considered some bicycle tires explode while saved below warm sunlight.Here, even with the undeniable fact that, we are offering an get away course for the air interior the bottle via keeping a balloon above.So the elevated air escapes into the balloon thereby swelling it.While the balloon saved below would not have a lot variations to observe. Its truly an straightforward test to do..

One situation is force applied to a moving object in the direction of its motion. The second situation is force applied to a moving object in the opposite direction of its motion. The third situation of force creating can be force that is applied to an object in motion that comes from arbitrary directions.

A speed skater moving across frictionless ice at 10.0 m/s hits a 5.0 m wide patch of rough ice. she slows steadily, then continu
Charra [1.4K]

To calculate the acceleration of the skater on the rough ice, we use the equation

v^2= u^2 + 2as

Here, u is initial speed when she hits the patch of ice and its value is 10 m/s and v is final speed when she left the patch of ice and its value is given 7.0 m/s and s is the width of patch of ice and its value is 5.0 m.

Substituting these values in above equation we get,

(7 m/s) ^2 = (10 m/s)^2 + 2 a \times 5.0 m \\\\ a = \frac{(70 - 100)(m/s)^2 }{ 10 m} = 3.0 m/s^2.

Thus, the acceleration of skater on the rough ice is 3.0 m/s^2

Svetlanka [38]

Answer: part a: 19.62m

part b: 19.62 m/s

part a: 2.83 secs

Explanation:If the air resistance is ignored then the swimmer experience free fall under gravity hence

u=0

a=9.81 m/s2

t=2 secs

s=ut+0.5at^2

s=h

h=0*2+0.5*9.81*2^2\\h=19.62 meters

Part b

v=u+at\\v=0+9.81*2\\v=19.62m/s

Part c

now we have h=2*19.62=39.24

39.24=0+0.5*9.81*t^2\\t^2=8\\t=2.83 secs
