<span>The answer is transformer. They utilize
electromagnetic induction to generate current. This is only possible in
alternating current due to the differential increase and decrease of electrical
current that induces changes in magnetic flux in the coil. This varies the
magnetic flux of the primary coil that generates current in the secondary coil.</span>
A: a person sitting on a train
Hence person could have a meal and not get food all over them.
Answer:
Equinox
Explanation:
It is an astronomical phenomenon that is repeated twice a year, in summer and winter, and that is caused because the axis on which our planet rotates is slightly inclined with respect to the plane of translation, this is its trajectory around the Sun.
For this reason there are two equinoxes a year, a phenomenon completely opposite to the solstice, but also marks the beginning of the spring and autumn seasons.
The equinoxes occur around March 20 or 21 and September 22 or 23, and it is the days when the Sun is exactly over the equator, which makes day and night more or less the same duration. The word ‘equinox’ comes from Latin and means precisely ‘same night’. In those two moments the part of the Earth closest to the Sun is the equator.
Explanation:
1D motion is motion in only one direction. To put it simply, it's motion along a line. For example, a train on a straight track has 1D motion.
2D motion is motion in two directions. A good example of this is a projectile launched at an angle. It has both vertical motion and horizontal motion.
As the balls continue to accelerate to the ground, the distance between them before the first ball hits the ground will increase.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Two identical heavy balls are dropped from the top of the Leaning Tower of Pisa. The second ball is dropped 1 s after the first ball. The first ball start falling 1s earlier than the second ball. Thus, the acceleration for first ball will be greater than the second ball.
Thus, the distance between them before the first ball hits the ground will increase.
