Answer:
a) 588,000 N
b) 294000 N
Explanation:
Given that
Density of water = 1000kg/m3
(g) = 9.8m/s2
volume is given as (V)= 5m*4m*3m
a) force will be equal to weight of water
b) at either end
[A = wh]
F = 294000 N
20-60minutes
Explanation:
Within 10-20minutes after a drink is consumed all of the alcoholic content has probably been absorbed into body.
Alcohol is absorbed into the body much more fast.
- It does not undergo digestion process like food.
- It can easily be absorbed into the blood stream.
- Alcohol is readily absorbed and carried round into the body.
- It doesn't get processed like food in the body where they pass through the digestive system.
- The body sees alcohol as nutrient.
- It carries it to the brain and other parts of the body.

Answer:
v = 21.03 m/s
Explanation:
given,
mass of skier = 45 kg
the slope of the snow = 10.0◦
coefficient of friction = 0.114
distance traveled = 300 m
speed = ?
Acceleration = g sin θ - µ g Cos θ
= 9.8 × Sin (10°) - 0.10 × 9.8 × Cos(10°)
= 0.737 m/s²
using equation of motion
v² = u² + 2 a s
v² = 0 + 2 × 0.737 × 300
v = 21.03 m/s
Speed of skier's after travelling 300 m speed is equal to 21.03 m/s
