We do not consider a car as living or alive because it does not fulfill some key characteristics of a living thing:
a car uses energy,is organjzed, moves and responds when you press the gas pedal why do...
As you drive down the road at 18 m/s , you press on the gas pedal and speed up with a uniform acceleration of 1.22 m/s2 for 0.70 s If the tires on your car have a radius of 33 cm, what is their angular displacement during this period of acceleration?
As you drive down the road at 14 m/s, you press on the gas pedal and speed up with a uniform acceleration of 1.22 m/s^2 for 0.65 s. If the tires on your car have a radius of 33 cm, what is their angular displacement during this period of acceleration? Answer should be in radians.
When you step on the brake pedal in your car, charge carriers flow from the battery to the rear brake lights. Suppose the wire connecting the switch at the pedal to the brake lights is made of copper and has a diameter of 1.3 mm . Part A If the current through the wire is 2.0 A , how long on average does it take an electron to travel from the switch at the pedal to one of the brake...
Problem 31.40 When you step on the brake pedal in your car, charge carriers flow from the battery to the rear brake lights. Suppose the wire connecting the switch at the pedal to the brake lights is made of copper and has a diameter of 1.1 mm . Part A If the current through the wire is 2.0 A , how long on average does it take an electron to travel from the switch at the pedal to one of...
A car company uses an average of 200 MWh of electricity per car when it produces 1000 cars. It will use 300 MWhs to produce the 1001st car. Electricity sells for $100/MWh and cars sell for $25,000. What is energy efficiency equal to when the company produces 1000 cars? Assuming it has no other costs, do you recommend the car company produce the 1001st car?
Toy car with m (mass) of 0.5kg moves at a v= 1.5m/s when it collides a spring. The spring is compressed 0.2m before toy car is brought to rest. Q. What is the spring constant of spring? - How does the energy flow diagram look like for this question? Could you please draw it if you can?
You are testing a new roller coaster ride in which a car of mass m moves around a vertical circle of radius R. In one test, the car starts at the bottom of the circle (point A) with initial kinetic energy Ki. When the car reaches the top of the circle (point B), its kinetic energy is Ki/4, and its gravitational potential energy has increased by Ki/2. What was the speed of the car at point A, in terms of...
How
do you do this
A car starting from rest moves in a straight line with a constant acceleration of 1.95 m/s for 14.0 s, then slows down to a stop with a constant eceleration of 2.75 m/s How far does it travel? meters
When we use the Ideal Gas Law equation to calculate moles of CO2 produced, why do we divide by 2 to find the moles of glucose fermented per minute? (Your answer must be clear and specific or you won't get credit.)
Your car tire is rotating at 3.4 rev/s when suddenly you press
down hard on the accelerator. After traveling 240 m, the tire's
rotation has increased to 6.6 rev/s. The radius of the tire is 32
cm.
What was the tire's angular acceleration? Give your answer in
rad/s^2.
Express the answer using two significant digits.
The answer I got is, approximately, 0.013405, but, apparently,
it's wrong.
