Answer:
Explanation: light waves against itself, which leads to internal interference of different wave component Which is also referred to as diffraction.
Diffraction causes beam of light to slowly spread out as it travels, so that some of the light will bend away from a straight line motion of the main part of the wave
By definition we have to:
A system or frame of reference are those conventions used by an observer (usually standing at a point on the ground) to be able to measure the position and other physical magnitudes such as speed and acceleration of one or several objects.
The numerical value of some magnitudes can also be relative to the reference system when we refer to the relative movement. There are always mathematical relationships between the observer and the relative magnitudes.
Answer:
C. a position from which something is observed
Answer:
The hiker has to climb 941.26 to ''work off'' the calories.
Explanation:
Let's first find out how much energy the hiker gets from 150 food calories.
This is:
Energy = 150 * 4186
Energy = 627.9 kJ
To burn all of this off, we set it equal to the gravitational potential energy, and then solve for the height.
This is:
Gravitational Potential Energy (G.P.E) = 629700
G.P.E = mass * gravity * height
Thus,
mass * gravity * height = 629700
68 * 9.81 * height = 629700
height = 941.26 meters

Answer: 55m
Explanation:
Given the following :
Driving speed = 90km/hr
Inattentive period (time) = 2.2s
Distance during inattentive period =
(driving speed * time)
Converting driving speed from km/hr to m/s
1000m = 1km
3600s = 1hour
Therefore,
90km/hr = (90 * 1000) / 3600
90km/hr = (90000)/ 3600 = 25m/s
Therefore ;
Distance during inattentive period =
(driving speed * time)
Distance during inattentive period = (25m/s × 2.2s) = 55m
Distance traveled during inattentive period is 55m
