Explanation:
This happens because the gas inside tend to expand because its temperature gets higher.
This is why the balloon that is put in a freezer for too long tend to gets smaller, because the gas temperature that is inside the balloon decreases.
(you can try it at home)
It is related to the temperature of the gas.
Answer:
two objects must have accelerations of equal magnitude.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
Where,
a is acceleration measured in
v and u is final and initial velocity respectively, measured in
t is time measured in seconds.
Acceleration constraint refers to a precise relationship between the acceleration of two physical objects.
An acceleration constraint says that in some circumstances two objects must have accelerations of equal magnitude.
Vo = 5.89 m/s Y = 1.27 m g = 9.81 m/s^2
Time to height
Tr = Vo / g Tr = (5.89 m/s) / (9.81 m/s^2) Tr = 0.60 s
Max height achieved is:
H = Vo^2 / [2g] H = (5.89 )^2 / [ 2 * (9.81) ] H = (34.69) / [19.62] H = 1.77 m
It falls that distance, minus Andrew's catch distance:
h = H - Y h = (1.77 m) - (1.27 m) h = 0.5 m
Time to descend is therefore:
Tf = √ { [2h] / g ] Tf = √ { [ 2 * (0.5 m) ] / (9.81 m/s^2) } Tf = √ { [ 1.0 m ] / (9.81 m/s^2) } Tf = √ { 0.102 s^2 } Tf = 0.32 s
Total time is rise plus fall therefore:
Tt = Tr + Tf Tt = (0.60 s) + (0.32 s) Tt = 0.92 s (ANSWER)
Answer:
Explanation:
a )
Force at the surface = FR
Value of g at height h = g( 1 - 2 h / R )
force at height h = F_R ( 1 - 2 h / R)
F_R / 2 = F_R ( 1 - 2 h / R)
= F_R - 2 F_R xh / R
F_R / 2 = 2 F_R x h / R
1 / 2 = 2h / R
4h = R
h = R / 4 . Ans
b )
Value of g at depth d = g( 1 - d / R )
force at depth d = F_R ( 1 - d / R)
F_R / 2 = F_R ( 1 - d / R)
= F_R - F_R xd / R
F_R / 2 = F_R x d / R
1 / 2 = d / R
2d = R
d = R / 2
