Answer: its b
Explanation: A river with a gradient that is less steep than those of youthful rivers and flows more slowly. A mature river is fed by many tributaries and has more discharge than a youthful river. Its channels erode wider rather than deeper
Answer:
Explanation:
mass of liquid m₁ = 161 g
temperature t₁ = 31.8
final temperature t₂ = 28.8
Let m g of ice melted to cool the liquid
heat gained = mass x latent heat of fusion + mass x loss of temp x s heat of water
= m x 80 + m x 1 x ( 31.8 - 28.8 ) ( latent heat of ice = 80 cals/g )
= 83 m
heat lost = 161 x 1 x ( 31.8 - 28.8 ) ( specific heat of water = 1 cal / g / k )
= 161 x 3
heat lost = heat gained
83 m = 161 x 3
m = 5.82 g
mass of remaining ice = 131 - 5.82
= 125.18 g
Answer:
669042 N upward
Explanation:
= Work done by gravity on pile driver
= Work done by beam
u = Initial velocity
v = Final velocity
m = Mass of pile driver = 2200 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Height the pile driver falls = 4.2 m
d = Bend in beam = 14 cm
Total work done = Change in Kinetic energy
The force the beam exerts on the pile driver while the pile driver is brought to rest is 669042 N upward
