Answer:
a. 0.5307 sec
b. 0.4458 m
c. =
Explanation:
Horizontal Motion
It describes the dynamics of an object thrown horizontally in free air. The initial horizontal velocity is maintained all the time since no horizontal forces are acting. The initial vertical velocity is zero at launch time, but it grows downwards powered by the acceleration of gravity.
The object hits the ground at a distance x from the point of launching, after having traveled a vertical distance , taking a time t to complete the travel. The formulas who relate the different magnitudes are
The horizontal velocity is the same regardless of the elapsed time
The plate of apple pie left the counter at a speed
The counter is high.
a.
Knowing that
We use this formula to compute t
At the moment when the plate hits the floor y=0
Solving for t
b.
c.
<u>Answer:</u>
The correct answer option is C. Kinetic energy from vibration.
<u>Explanation:</u>
The energy of the random motion of the particles of an object is referred to as the internal energy of that object (substance). So the type of energy that makes up most of the internal energy of a solid substance is kinetic energy from vibration.
Internal energy is related to the temperature. When heat is supplied to an object, the molecules vibrate and energy of these molecules increases.
Here space craft is moving with constant velocity
Now due to gas leakage it will have acceleration perpendicular to velocity
it is given that acceleration is always perpendicular to velocity
So it will neither increase nor decrease the velocity
it will only change the direction of the motion
so it is the centripetal acceleration of the space craft
in this case we will say that path of the space craft will be circular path
<em>So it will perform Uniform Circular Motion and its path will be a circle</em>
Water surface waves are examples of waves that are both longitudinal and transverse waves. As the wave travels through the water, a clockwise circles is observed. Therefore, the answer to this item is letter D. All the rest of the choices do not describe the water surface waves.
