A helium weather balloon is filled to a volume of 219 m3 on the ground, where the pressure is 754 torr and the temperature is 29

Novosadov [1.4K]

Answer:

$V_2 = 606.9 m^3$

Explanation:

By ideal gas equation law we know that

PV = nRT

now we know that when balloon rises to certain level then the number of moles will remains same

so we can say

$n_1 = n_2$

$\frac{P_1V_1}{RT_1} = \frac{P_2V_2}{RT_2}$

now plug in all data to find the final volume of the balloon

$\frac{754\times 219}{R(298)} = \frac{210 \times V_2}{R(230)}$

$V_2 = \frac{230\times 754 \times 219}{210 \times 298}$

$V_2 = 606.9 m^3$

If a high jumper needs to make his center of gravity rise 1.50 m, how fast must he be able to sprint? Assume all of his kinetic

sergiy2304 [10]

Answer:

v = 5.42 m/s

Explanation:

given,

height of the jumper = 1.5 m

velocity of sprinter = ?

kinetic energy can be transformed into potential energy

$m g h = \dfrac{1}{2}mv^2$

$g h = \dfrac{1}{2}v^2$

$v =\sqrt{2gh}$

$v =\sqrt{2\times 9.8 \times 1.5}$

v = 5.42 m/s

Speed of the sprinter is equal to v = 5.42 m/s
