Answer:
Bacteria, Hydra, Copperheads, Blackworms, and Strawberries
Explanation:
Answer:
the first one
Explanation: the first one because they were all on two different continents so when they seperated half of the species went on one continent and the other half went onto another one
Answer:
(A) 10132.5Pa
(B)531kJ of energy
Explanation:
This is an isothermal process. Assuming ideal gas behaviour then the relation P1V1 = P2V2 holds.
Given
m = 10kg = 10000g, V1 = 0.1m³, V2 = 1.0m³
P1 = 101325Pa. M = 102.03g/mol
P2 = P1 × V1 /V2 = 101325 × 0.1 / 1 = 10132.5Pa
(B) Energy is transfered by the r134a in the form of thw work done in in expansion
W = nRTIn(V2/V1)
n = m / M = 10000/102.03 = 98.01mols
W = 98.01 × 8.314 × 283 ×ln(1.0/0.1)
= 531kJ.
Answer:
F = 0.179 N
Explanation:
given,
length of the rod = 0.759 m
mass of the rod = 1.03 kg
force = ?
initial angular speed = 0 rad/s
final angular speed = 6.87 rad/s
time interval = 9.95 s
the angular acceleration
moment inertial of the rod
torque produced by the rod τ = I α
torque is also equal to τ = F L
now,
F L = I α
F = 0.179 N
