Answer:
A steady decline in driving ability
Explanation:
Alcohol consumption impairs the functioning of the central nervous system. The impairment can range from mood improvement to unconsciousness. As the blood alcohol level (BAL) rises the impairment gets severe. Driving is a complex task that requires the central nervous system to function properly.
Any impairment to the central nervous system leads to a decline in driving activity.
Answer:
center of mass of the two masses will lie at x = 2.52 cm
center of gravity of the two masses will lie at x = 2.52 cm
So center of mass is same as center of gravity because value of gravity is constant here
Explanation:
Position of centre of mass is given as
here we have
now we have
so center of mass of the two masses will lie at x = 2.52 cm
now for center of gravity we can use
here we have
now we have
So center of mass is same as center of gravity because value of gravity is constant here
Mass of car, m = 4060 kg
Spring constant, k = 8.00 x 10⁶ N/m
Spring compression, x = 3.72 cm = 3.72 x 10⁻² m
Let the car strike the wall with speed v m/s.
The kinetic energy of the car is released into the stored energy of the spring (if losses are ignored), so that
(1/2)mv² = (1/2)kx²
(4060 kg)*(v m/s)² = (8 x 10⁶ N/m)(3.72 x 10⁻² m)²
4060 v² = 1.1701 x 10⁴
v = 1.6513 m/s
Answer: 1.65 m/s (nearest hundredth)
Capacity of the gas tank . . . Liters
Distance to the next town . . . Kilometers
Smaller units would produce bigger numbers.
It's best to use the units that produce the handiest, most convenient numbers. That way, it's easier to remember the number, write it down without mistakes, and tell other people about it.

What is the x <span>coordinate of the particle?
Answer: </span>x = Rcos(θ(t<span>))
</span>What is the y <span>coordinate of the particle?
Answer: </span>y = Rsin(θ(t<span>))
Correct answer is </span>r⃗ (t) = Rcos(θ(t))i + Rsin(θ(t))i^j<span>^</span>
