Answer:
whirl a rock at the end of a string and it follows a circular path. if the string breaks, the tendency of the rock is to stop
<span>Answer: V/n = constant</span>
PV = nRT ....... ideal gas law
divide state 1 by state 2
WARNING: CONVERT ATM TO KPA
(0.923atm)(150ml) / (0.987atm)(V2) = 1
1 because constant temperature
solve for V2. all the best
Answer:
2.84 seconds
Explanation:
t = ?
distance = 125
Velocity origianal = 60 m/hr = 88 ft/s
AVERAGE velocity = 88/2 = 44 ft/s
44 t = 125
t = 125/44 = 2.84 s
Answer:
108.8 m /s
θ = 21°
Explanation:
Centripetal acceleration = ω² R
=( 13 )² x .602
= 101.74 m/s²
tangential acceleration a_t = angular acceleration x R
= 64.1 x .602
= 38.58 m /s²
Total acceleration R
R² = ( 101.74 )² + ( 38.58 )²
R = 108.8 m /s
angle required be θ
Tanθ = tangential accn / radial accn
= 38.58 / 101.74
θ = 21°
