Answer:
48.5 hp
Explanation:
= mass of the car = 1200 kg
= initial speed of the car = 25 km/hr = 6.94 m/s
= final speed of the car = 100 km/hr = 27.78 m/s
= time interval = 12 s
Power output of the engine is given as
W
we know that , 1 hp = 746 W

First one is B, second one is A
Answer: 2.068*m
Explanation: According to work energy-theorem , the workdone in accelerating the electron equals the energy it would give off in terms of light.
workdone= qV
energy = hc/λ
q=magnitude of an electronic charge= 1.602*
h= planck constant = 6.626*
c= speed of light =2.998*
v= potential difference= 6*
λ= wavelength=unknown
by making λ subject of formulae we have that
λ=
λ = 6.626* * 2.998* / 1.602* * 6*
λ =
by doing the necessary calculations, we have that
λ = 2.068*m
Math is not my strongest area. However, English poses no problems at all for me. You misspelled “wrap”. You buy gift wrap to wrap a gift. You buy an Eminem C.D. to listen to “rap” music. You “rap” on someone’s door.
