Answer:
θ = 73.6º
Explanation:
To solve this exercise, let's use Newton's second law. Let's set a reference system where the x-axis is parallel to the inclined plane
with trigonometry we can find the components of the weight
sin θ = Wₓ / W
cos θ= W_y / W
Wₓ = W sin θ
W_ = W cos θ
Y axis
N - W_y = 0
N = W_y
X axis
Wₓ - fr = m a
mg cos θ - fr = m a
indicate that friction is zero, fr = 0
cos θ = a / g
θ = cos⁻¹
let's calculate
θ = cos⁻¹
θ = 73.6º
Answer:
3.) 0.3 m
Explanation:
Given parameters:
Torque = 40Nm
Force = 133N
Unknown:
Distance from the nut that the mechanic must apply the force = ?
Solution:
Torque is the force that causes an object to rotate on its axis;
Torque = force x distance
Distance = = 0.3m
Energy is related to the change of state represented by the model in this way - C. Atoms lose energy as a gas changes to a solid.
As a certain gas is changing its state into that of a solid material, its atoms are going to lose some energy.
It would be 50000000 in mL
Clouds form when water vapor in the air condenses into visible water droplets or ice crystals
