Explanation:
The energy that substance contain is. B.heat
The answer that best completes the statement above is COST-EFFECTIVE ANALYSIS. Occasionally, DUI checkpoints, also known as sobriety checkpoints are being established by police on the roadsides for safety purposes. This is also the same with the seatbelt laws. Both of these aim in decreasing motor-vehicular accidents. Comparing these two, we call it cost-effective analysis. When we say cost-effective, the effectivity of the action if being assessed in relation to the cost it takes to enforce the rule.
It’s 1.255 i believe ! good luck ahah
Answer:
15.6 m
Explanation:
d = diameter of the wheel = 43 cm = 0.43 m
r = radius of the wheel = (0.5) d = (0.5) (0.43) = 0.215 m
w₀ = initial angular velocity = 86 rpm = 9.01 rad/s
v₀ = initial linear speed = r w₀ = (0.215) (9.01) = 1.94 m/s
w = final angular velocity = 362 rpm = 37.91 rad/s
v = final linear speed = r w = (0.215) (37.91) = 8.15 m/s
t = time taken = 3.1 s
Using the equation
v = v₀ + at
8.15 = 1.94 + a (3.1)
a = 2 m/s²
d = distance traveled by a point at the edge of the wheel
Using the equation
d = v₀ t + (0.5) at²
d = (1.94) (3.1) + (0.5) (2) (3.1)²
d = 15.6 m
