Answer:
0.25 L
Explanation:
= Initial pressure = 1 atm
= Initial Temperature = 20 °C
= Initial volume = 4.91 L
= Final pressure = 5.2 atm
= Final Temperature = -196 °C
= Final volume
From ideal gas law we have
The pressure experienced by the balloon is 0.25 L
Answer:
a = 64 ft / s²
Explanation:
The force in a spring is given by Hooke's law
F = -k x
Let's use the initial data to calculate the spring constant
k = F / x
Reduscate to the English system
x = 3 in (1foot/12 in) =0.25 foot
k = 0.3 / 0.25
k = 1.2 lb / foot
Now we can use Newton's second law
F = ma
a = F / m
a = -k x / m
m = w / g
m = 0.3 / 32 = 0.009375
x= 6 in (1foot /12 in)= 0.5 foot
a = - 1.2 0.5 / 0.009375
a = 64 ft / s²

i DONT KNOW
Explanation:
why? because i dont knowXD
Answer:
Explanation:
We shall consider the balance of forearm . The weight is balanced by tension created in the bicep of forearm.
The weight of forearm will act downward . Let it be W. Tension T of bicep will pull the forearm upwards . Bicep muscle is attached at a point between palm and elbow. Its other end is attached with hind arm . If we hold the forearm parallel to ground , weight acts vertically downwards and tension in bicep makes some angle with the vertical . Let it be θ.
Vertical component of tension T
= T cos θ . It will balance W .
T cos θ = W
T = W / cos θ
the value of cos θ will always be less than 1.
so T > W . or
tension in bicep is more than weight of forearm.
