Answer
Liquid
Explanation
There are four states of matter. Gas, liquids, plasma and solids.
Solids has a definite shape.
Gas and plasma has no definite volume.
Liquids are made up of very small vibrating particles called molecules that are held together by intermolecular forces. This makes the liquid to have a definite volume and no definite shape.
b. 49
c. 14
d. 43
e. 4.3
Answer:
It also increases
Explanation:
The strength of the gravitational force between two objects depends on two factors, mass, and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
b. Which force accelerates the car down the ramp?
c. Which force acts against the motion of the car?
A. x>0 but xB. x=A
C. x<0.
D. x=0.
E. None of the above
Answer:
The correct answer is option E. This is because when a body is undergoing simple harmonic motion, the displacement, velocity and acceleration are constantly changing with respect to position and time.
Explanation:
When the body is passing through the equilibrium position so that the displacement at that point is zero, the velocity at that point is either maximum or minimum (Vmax or Vmin) which is dependent on which way the body is moving (the chosen direction of positive sense of motion). At the equilibrium position the acceleration is zero because the net force acting on the body is zero (that is the sun of the forces acting on the body along both directions of motion is equal to zero). Also when the body is at either its maximum positive displacemt, x = +A, or its maximum negative displacement x = -A, the velocity is zero and the body is instantaneously at rest. At this points the force (in either direction) acting on the body has it maximum value and as a result the acceleration has it maximum magnitude whether negative or positive depending on the chosen direction positive sense of motion.
At any other point in the course of the SHM (simple harmonic motion), the velocity (V) and acceleration (a) of the always have nonzero values and as a result they are never simultaneously equal to zero.
Thank you very much reading and I hope this is helpful to you.
Non-examples of speed include acceleration, direction, time, distance, inertia, momentum, and force. These concepts relate to other aspects of motion, not the rate of motion, which speed measures.
Non-examples of speed would be any factors or measures that don't directly pertain to the measurement of an object's change in position or distance over time. These could include factors such as acceleration, which involves the rate of change of speed; direction, which becomes a concern when we deal with velocity, not speed; and elements like time or distance separately.
For instance, projections about gravitational pull on vehicles while in motion would be non-examples because they relate more to the forces affecting the motion, rather than the motion itself. Similarly, an object's inertia or momentum, and the force applied to an object also do not exemplify speed, as they pertain to mass and force, not the rate of motion.
It's also essential to distinguish between instantaneous speed, average speed (total distance divided by elapsed time), and constant speed (speed that doesn't change over time). These are all variations of speed, but one concept isn't interchangeable with the others based on the context of the motion being described.
