Answer:
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Answer:
vehicle of mass 100kg is moving with 72 km/h then after a driver apply a break and car come to rest in 20sec them calculate rediation and force
Explanation:
Given,
Mass of car, M=2000kg
Velocity, V=72×
18
5
=20ms
−1
Apply kinematic equation of motion
v
2
−u
2
=2as
0−20
2
=2a×20
a=−10ms
−2
Breaking force, F=ma=2000×10=20 kN
Apply first kinematic equation
v=u+at
t= a v−u = −100−20
=2 sec
Breaking force is 20 kNand time is 2sec.
