Acceleration I’m pretty sure
Answer:
Explanation:
The formula to find average acceleration is a=Δv/Δt.
Convert 216 km/hr to m/s
216 km/hr * 1000 m/km * 1 hr/60 mins * 1 min/60 secs = 60 m/s
So a= (60 m/s)/(5.0*10^-3) = 12000 m/s^2
Put that into scientific notation to get 1.2*10^4 m/s^2
Answer: 888.45 K or 615.3 °c
Explanation:
According to Gay Lussacs law which states that at constant volume, pressure of an ideal gas is directly proportional to it's absolute temperature.
P/T = Constant
Therefore, P1/T1 = P2/T2
P1 = 6.7 atm
T1= 23°c = 273.15 + 23 = 296.15K
Since P2 is tripled, then,
P2 = 6.7 x 3= 20.1 atm
T2 = (20.1 x 296.15) ÷ 6.7
T2 = 888.45 K
Or in celcius 615.3°c
Answer:
Young's modulus of this tendon is .
Explanation:
Given that,
Length of the tendon, l = 19 cm
It is stretched by 4.5 mm,
Force, F = 11.3 N
Average diameter, d = 8.2 mm
Radius, r = 4.1 mm
The formula of Young's modulus of this tendon is given by :
So, the Young's modulus of this tendon is . Hence, this is the required solution.
