<span>Reflection
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.</span>
Explanation:
Work is the dot product of the force and displacement vectors.
W = F · d
In other words, it is the force times the parallel component of the distance.
W = F d cos θ, where θ is the angle between the force and distance.
Answer:because the parachute is built so the wind will push up on it make the man/woman glide or fall slowly will a stone which has a lot of desentity
falls through the air faster do to is weight and shape .
Explanation:
Each of the choices may be considered right depending on the use
of context or on how terms are defined, but the one that is most correct is:
"Controlled experiments
produce valid data"
Controlled experiments are experiments in which factors which are
not the interest of the study or which are not being studied are controlled or
accounted for in the design, so that resulting data are less likely to be
caused by some anomaly or by some variable other
than those being
studied. In usual research scenarios it is not the data itself that
is acted upon in the <span>experiment - it is the experiment itself, the
factors and the physical processes that will eventually yield data.</span>
The forces are unbalanced because Jasper weighs more than Gemma
The side that Gemma is on will only move upwards if the force exerted on the other side is greater than the force exerted by Gemma. In this case, force is referring to the weight of the children. Therefore, in order for Gemma to go upwards, Jasper must weigh more than her.
