The correct answer for velocity if acceleration is opposite is:

* An initial velocity that is faster than a final velocity

The given parameters are acceleration and initial velocity, it is asked to find the final speed of the body

In kinematics, position, velocity, and acceleration are quantities that are related.

The magnitude and direction of the acceleration are given by the resultant force on the body, in many cases the resultant force is constant in various time intervals, therefore the is acceleration is constant in these intervals even though it may have a different value in each one.

The velocity of the body is defined by the change in position of the body in the unit of time, in the most common case of a system with constant acceleration the velocity is given by

$v_f$ = v₀ + a t

where v₀ and $v_{f}$ are the initial and final velocities of the body, a is the acceleration and t is a time scalar: the bold letters indicate vectors.

If the velocity has a direction and the acceleration is contrary to the equation, we can see that the final velocity must decrease as time advances. Therefore the correct statement is: O An initial velocity that is faster than a final velocity.

If you apply 100.0 N of force to lift an object with a single, fixed pulley, then what is the resistive force?

quester [9]

<span>If you apply 100.0 N of force to lift an object with a single, fixed pulley, then the resistive force is also equivalent to 100 Newtons of force. Since the weight of the object was not mentioned, it is assumed that it has already been taken into account in the 100 N value of force. This follows Newton's law of motion of equal action and reaction.</span>

What do you think causes such change in wave velocity?

saveliy_v [14]

Example: Increasing the tension in A string causes the speed of waves on the string to increase. Since the wavelengths of the standing waves remains constant, this results in a larger frequency of oscillations in the string, which we percieve as a higher pitch when the string vibrates the air.

If you use a marble of radius 11 mm for mercury, how far from the sun must you place your outermost planet? express your answer

mariarad [96]

Well so we know that 11mm is 2440km so 1mm is 2440/11 which is 221.8.
Ans we know that Neptune is the farthest and the distance is 4.498 billion km the we would divide that by 221.8 to get answer.
Ans=2.36km

An ice skater has a moment of inertia of 5.0 kgm2 when her arms are outstretched. at this time she is spinning at 3.0 revolution

givi [52]

With arms outstretched,
Moment of inertia is I = 5.0 kg-m².
Rotational speed is ω = (3 rev/s)*(2π rad/rev) = 6π rad/s
The torque required is
T = Iω = (5.0 kg-m²)*(6π rad/s) = 30π

Assume that the same torque drives the rotational motion at a moment of inertia of 2.0 kg-m².
If u = new rotational speed (rad/s), then
T = 2u = 30π
u = 15π rad/s
= (15π rad/s)*(1 rev/2π rad)
= 7.5 rev/s

Answer: 7.5 revolutions per second.
