Answer:
The amplitude of the subsequent oscillations is 13.3 cm
Explanation:
Given;
mass of the block, m = 1.25 kg
spring constant, k = 17 N/m
speed of the block, v = 49 cm/s = 0.49 m/s
To determine the amplitude of the oscillation.
Apply the principle of conservation of energy;
maximum kinetic energy of the stone when hit = maximum potential energy of spring when displaced
Therefore, the amplitude of the subsequent oscillations is 13.3 cm
Answer:
a). v=2776 m/s
Explanation:
The speed of the water droplet for the fish be successful is
Taking the distance in axis 'x' and 'y'
The time is the velocity in axis 'x' with the angle 70 so
Now using the time in terms of velocity the motion in axis 'y' can find the velocity to be the fish successful
Answer: Within any frame of reference that is accelerating
Special relativity was proposed on 1905 by Einstein, who developed his theory based on the following two postulates:
1. <em>The laws of physics are the same in all inertial systems. There is no preferential system.
</em>
2. <em>The speed of light in vacuum has the same value for all inertial systems.
</em>
Focusing on the first postulate, it can be affirmed that <u>any measurement on a body is made with reference to the system in which it is being measured</u>.
Now, taking into account that an inertial reference system is the one that complies with the principle of inertia:
<em>"For a body to have acceleration, an external force must act on it."</em>
The correct answer is
Within any frame of reference that is accelerating
I think it's D. Usually, to find the volume of an irregularly shaped object, you put it in water with a labeled beaker to measure how much the water rises. The balance would be used to measure the mass in grams.
In which it is the plane in which charges move. for example in electromagnetic waves polarization<span> means the plane in which electrons oscillate. ... it is the distribution of electric charges (electron) in an object. </span>induction<span> of charges takes place in some insulators just by some mechanical interaction such as rubbing</span>
