Answer:
Pressure applied by the man= 285103.125 or 41.35
Explanation:
Pressure is defined as the perpendicular force applied per unit area.
i.e.
Now,
where, = mass of the body(man) = 93 kg
= acceleration due to gravity of Earth = 9.81
covered is equal to the area of both stilts(a man generally stands on two feet)
therefore
and putting in the values, we get,
Now we need to convert to our required units:
(We can get the above result by individually converting kg to lb and meters to inches respectively)
Using the above relations we get,
Answer:
(a) 0 (b)
Explanation:
Given that,
Mass of a supertanker,
The engine of a generate a forward thrust of,
(a) As the supertanker is moving with a constant velocity. We need to find the magnitude of the resistive force exerted on the tanker by the water. It is given by :
F = ma, a is the acceleration
For constant velocity, a = 0
So, F = 0
(b) The magnitude of the upward buoyant force exerted on the tanker by the water is equal to the weight of the ship.
F = mg
Hence, this is the required solution.
Answer:
Explanation:
Since the temperature in degrees Fahrenheit in terms of the Celsius is given by the formula and the temperature in degrees Celsius in terms of the Kelvin temperature is given by the formula
, we can use the second formula and substitute it straight into the first formula (since a simplification is not being asked), obtaining
.
