Acceleration is constant in free fall. So it would again be 9.8 m/s².
Coplanar molecules are determined by its structure through the geometric configuration of the given molecule. Only linear configurations are coplanar unlike the trigonal planar, tetrahedral,etc. configurations. The sp hybridization also tells whether the arrangement is coplanar or not.
Answer:
if the car is traveling north, the person is also traveling north,
If the car turns to (left) to the west, the person will still tend to travel to the north and will slide to the right (north) on a slippery car seat.
Answer:
0.2 m/s
Explanation:
given,
mass of astronaut, M = 85 Kg
mass of hammer, m = 1 Kg
velocity of hammer , v =17 m/s
speed of astronaut, v' = ?
initial speed of the astronaut and the hammer be equal to zero = ?
Using conservation of momentum
(M + m) V = M v' + m v
(M + m) x 0 = 85 x v' + 1 x 17
85 v' = -17
v' = -0.2 m/s
negative sign represent the astronaut is moving in opposite direction of hammer.
Hence, the speed of the astronaut is equal to 0.2 m/s
Answer:
e) 0.099
Explanation:
For an adiabatic expansion:
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
is the adiabatic index (which is 
for an ideal monoatomic gas
In this problem, we have
since the volume increases by a factor 4
We can re-write the equation to find by what factor the pressure changes:
