<span>Answer:
So it gets to the top of the ramp and stops. The parallel force pushing it down the ramp is mg sin θ, but for it to move, the frictional force must be overcome. This frictional force is μmg cos θ, where μ is the coefficient of static friction. For movement, then,
mg sin θ > μmg cos θ ==> tan θ > μ ==> θ > arctan 0.5 = 26.565° ==> θ = 27°</span>
The last one, Kinetic energy bc it is taking them to school
The kinetic theory of gases is a simple, historically significant model of the thermodynamic behavior of gases, with which many principal concepts of thermodynamics were established. The model describes a gas as a large number of identical submicroscopic particles, all of which are in constant, rapid, random motion
Answer:
Answer:
D) by using military force.
Explanation:
Typically, people like Mussolini and Stalin gain popularity in trying times by promising a type of well-being to a group or nation of stricken people, in which they gain huge amounts of popularity at once. Typically they are then elected to some seat of power, in which, with popularity and most likely the military on their side, they would overthrow the current government. The next step taken is to suppress any opposition or even those who don't fully support the party. This can be given out in two ways, which is through force (especially opposition), or providing benefits to those who are in the party (to draw those who are not exactly supporting to support for the benefits).
With "popular" support, as well as military control, the overthrow is complete, and the group is established in power.
Answer:
-48 N
Explanation:
mass of door (m) = 4 kg
acceleration of the door = 12 m/s^{2}
force exerted by the person = 48 N
From Newton's third law of motion, action and reaction are equal but opposite. Therefore the force exerted on the door by the person which is 48 N will be the same as the force exerted on the person by the door but opposite in its direction, and this would be - 48 N
