If both the net force and the mass are doubled, the acceleration will be unchanged.
Answer:
The speed of the raindrop is 11.55 m/s.
Explanation:
We need to find the speed of the rain in the "y" direction. We have:
: speed of the raindrop at 60° (vertical) =?
: speed of the car = 20 m/s (in the "x" direction)
Hence, the speed of the car and the speed of the raindrop are related by:
Therefore, the speed of the raindrop is 11.55 m/s.
I hope it helps you!
Answer:
I don't know if these are the biggest but they are burning fossil fuels factories that release CO2 driving cars and cutting down trees.
Answer:
Explanation:
given,
rotational inertia, I = 474.0 kg·m²
decrease in angular velocity
ω₁ = 26.2 rad/s ω₂ = 0 rad/s
time = 204 s
torque = ?
α = 0.128 rad/s²
frictional torque acting by the flywheel is equal to 60.88 N.m
Answer:
a) h = 8.02 10³ m b) yes
Explanation:
a) The pressure in a fluid is given by
P = ρ g h
The pressure in this case is the atmospheric pressure, 1.013 105 Pa, let's clear the height (h)
h = P / ρ g
h = 1.013 10⁵ / (1.29 9.8)
h = 8.02 10³ m
b) The height of Mount Everest is 8848 m
It is above this height, according to this model there would be no air to breathe
