Answer: Kinematics
Explanation: Kinematics is a branch of mechanics focusing on describing motion of objects, excluding from consideration the study of forces that act on such objects.

Not without "help" it can't. There are two versions of this. One is that it is impossible to take heat from something and convert it completely into work - there has to be some waste at a lower temperature. The other is that heat will not "spontaneously" go from a colder place to a warmer place. So, a domestic fridge needs a device to transfer the heat, that's that buzzing sound of a motor driving a refrigerant round in a cycle, taking heat out the fridge and making the surrounding warmer. It's also called a heat pump. The area near where the pump puts its heat can be felt to be warm.
Answer:
x=2.4t+4.9t^2
Explanation:
This equation is one of the kinematic equations to solve for distance. The original equation is as follows:
X=Xo+Vt+1/2at^2
We know that the ball starts at rest meaning that its initial velocity and position is zero.
X=0+Vt+1/2at^2
Since it is going down the ramp, you can use the acceleration of gravity constant. (9.81 m/s^2) and simplify that with the 1/2.
X=Vt+4.9t^2
Note: Since the positive direction in this problem is down, you are adding the 4.9t^2, but if a question says that the downward direction is negative, you would subtract those values.
Now, substitute in your velocity value.
X=2.4t+4.9t^2
Two forces 3N and 4N act on a body in a direction due north From East, the equilibrant's angle is given by 
.
<h3>What are equilibrium and resultant force?</h3>
The equilibrium force is the balanced force when the net force acting is zero and is the exact opposite of the consequent force. The resultant force is one single force replaced by numerous forces.
<h3>Briefing:</h3>
3N and 4N are the two forces pulling on a body.
The forces work along the North and the East, which are perpendicular to one another.
The resultant of the forces, which is provided by the equilibrant force,
R = √(3)²+(4)²
R = 5N
From East, the equilibrant's angle is given by
