Answer:
The white car will cover the most distance every second.
Explanation:
The formula for the uniform speed of an object is given as follows:
where,
s = distance covered by the object
v = speed of the object
t = time required
Now, if we assume time to be constant at 1 s. Then the distance covered by each car will be directly proportional to the speed of the car. Hence, the car with the greatest speed will travel the greatest distance in 1 second.
We, have:
Speed of white car > Speed of red car > Speed of green car
<u>Therefore, the white car will cover the most distance every second.</u>
10.92N
Explanation:
Given parameters:
Mass of the truck = 2.964kg
velocity = 7m/s
Time = 1.9s
Unknown;
Average force on the car = ?
Solution:
The force acting on the car is a function of its mass and acceleration according the newton's second law of motion.
Force = mass x acceleration
Since acceleration = 
Force = mass x
Force = 
= 10.92N

a) KE=energy required to make them move=1800J
b) KE=1/2*mv^2, so 
J
Answer:
Explanation:
Given:
temperature of source reservoir, 
temperature of sink reservoir, 
energy absorbed from the source, 
work done, 
a.
<u>Now change in entropy of the surrounding:</u>
<em>Since heat engine is a device that absorbs heat from a high temperature reservoir and does some work giving out heat in the universe as the byproduct.</em>
b.
<u>We know Carnot efficiency is given as:</u>
<u>Now the Carnot work done:</u>
.......................(1)
c.
From eq. (1) we have the Carnot work, so the difference:
Now, we find:
D. All of the above.
These are all places you could get information from, therefore making them all sources.
