it is actually natural resources
Answer
given,
mass of the dragster = 835 Kg
initial speed, u = 0 m/s
final speed, v = 110 km/h = 110 x 0.278 = 30.58 m/s
time, t = 0.90 s
a) Change in momentum
Δ P = m v - m u
Δ P = 835 x ( 30.58 - 0 )
Δ P = 25534.3 kg.m/s
b) average force exerted on the car
change in momentum = Force x time
25534.3 = F x 0.9
F = 28371.44 N
c) The exerted force is due to friction because the motion of the dragster is because of friction.
During photosynthesis: Light energy is absorbed by chlorophyll, a green substance found in chloroplasts in some plant cells and algae. Absorbed light energy is used to convert carbon dioxide (from the air) and water (from the soil) into a sugar called glucose. Oxygen is released as a by-product.
