It’s a vector quantity, which means it possesses both magnitude and direction. So the SI unit would be B)kg•m/s
Answer:
54 km/h
Explanation:
given,
speed of the biker = 36 Km/h
time = 10 s
acceleration = 0.5 m/s²
speed at which it crosses the finish line = ?
v = 36 x 0.278 = 10 m/s
using equation of motion
v = u + a t
v = 10 + 0.5 x 10
v = 15 m/s
v = 15 x 3.6 = 54 km/hr
speed at which the biker crosses the finish line is equal to 54 km/h
The energy absorbed by photon is 1.24 eV.
This is the perfect answer.
Water and baking soda can be used, too.
