Answer:
Explanation:
We know that energy of a photon
E =hυ = hc/λ
h = planks constant, = 6.63×10^{-34} J s
υ= frequency of the wave, c= speed of light, = 3×10^8 m/s
λ = wavelength = 3×10^{-15} m
Answer:
a. slope=rise/run
rise=2
run=10
slope=2/10
slope=1/5
used point (0,0) and (10,2)
slope(m)=1/5
b. area= 0.5bh
0.5×50s×10m/s
a=25s×10m/s
a=250m
c.the area represents the total distance traveled after 50s by the toy
the slope represents the acceleration of the toy
the unit of slope is m/s²
slope=rise/run
slope(m)=(2m/s)÷10s
m=(2/10)m/s/s
m=(1/5)m/s²
.=0.2m/s²

The answer would be false
Hence, the horizontal velocity of the rover is 1.73 m/s
