Answer:
F = 2 * 30 / 5 = 12 N to stop forward motion
F = 2 * 40 / 5 = 16 N to accelerate to 90 degrees
(12^2 + 16^2)^1.2 = 20 N average force applied
force=mass × acceleration
mass=force ÷ acceleration
acceleration=force ÷ mass
This is a diagram from above, the air resistance is oppose to movement, the bird is moving forward given its force is bigger.
Answer:
the box has vertical force on the table
Explanation:
There can be no single isolated force, for every action there must be a force of reaction of ingual magnitude and direction, but in the opposite direction
To solve this problem it is necessary to apply the concepts related to the Stefan-Boltzman law that is responsible for calculating radioactive energy.
Mathematically this expression can be given as
Where
A = Surface area of the Object
Stefan-Boltzmann constant
e = Emissivity
T = Temperature (Kelvin)
Our values are given as
Replacing at our equation and solving to find the temperature 1 we have,
Therefore the the temperature of the coldest room in which this person could stand and not experience a drop in body temperature is 12°C
