Answer :
First, with m = 0.123 kg, pressure force, T = 255N, and length = 10 m, Using the formula V = ?, we've haste of 144 m/s.
After 20 milli alternate = 0.02 s, the first palpitation would have run along the line for
This means that it only left 10m-2.88 m = 7.12 m for the 2 pulsesto run.
therefore, the distance which the 2 beats will first meet would be
from the position where the first pulse is transferred.
exactly the same as the answer at the reverse)
remaining distance is divided by 2 as the 2 pulse are moving with the same speed towards each other.
Mass
Mass is the volume of matter in a physical body. It's also a measure of the body's indolence, the resistance to acceleration( change of haste) when a net force is applied. An object's mass also determines the strength of its gravitational magnet to other bodies.
The SI base unit of mass is the kilogram( kg). In drugs, mass isn't the same as weight, indeed though mass is frequently determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known millions. An object on the Moon would weigh lower than it does on Earth because of the lower graveness, but it would still have the same mass. This is because weight is a force, while mass is the property that( along with graveness) determines the strength of this force.
