A motorist drives south at 24.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.20 min, and finally travels nort

grigory [225]

Answer:

magnitude m = 5440.26 M

average speed is = 25.05 m/s

average velocity = 14.62 m/s

Explanation:

given data

speed v1 = 24 m/s

time t1 = 3 min = 180 s

speed v2 = 25 m/s

time t2 = 2.2 min = 132 s

speed v3 = 30 m/s

time t3 = 1 min = 60 s

total time = 6.2 min = 372 s

to find out

displacement in m and average speed and average velocity

solution

so we find here displacement

displacement = vt .............1

displacement 1 = 24 × 180 = 4220 m south = -4220 j ..........2

displacement 2 = 25 × 132 = 3300 m west = -3300 i ...........3

distance 3 = 30 × 60 = 1800 m

displacement = 1800 cos45 -i + 1800 cos45 j

displacement = -1272.79 i + 1272.79 j .............4

so total displacement D = equation 2 + equation 3 + equation 4

total displacement D = -4220 j -3300 i -1272.79 i + 1272.79 j

total displacement D = -2947.21 j - 4572.79 i

so magnitude m = √(-2947.21)² + (-4572.79)² )

so magnitude m = 5440.26 M

and

average speed is = total distance / time

average speed is = (4220 + 3300+ 1800 ) / 372

average speed is = 25.05 m/s

and

average velocity = total displacement / time

average velocity = 5440.26 / 372

average velocity = 14.62 m/s

Photons of infrared radiation with wavelengths longer than those of visible light will have what kind of energy compared to that

densk [106]

Answer:

Infrared photons carry lower radiation energy than the visible light.

Explanation:

Each photon carries an energy that is directly proportional to its frequency, being this proportionality constant the Planck's constant h.
So, we can write the energy of a single photon as follows:

$E = h*\nu (1)$

Since there exists an inverse relationship between wavelength and frequency, and infrared radiation has longer wavelengths, this means that its frequency is lower than the one of the visible light.
So, an infrared photon carries less energy that one of the visible light.
