The block that has a higher temperature describes the thermal energy of these blocks. Thermal energy is a measure of internal energy - therefore, the block with the higher temperature has more internal energy than the block with the lower temperature, meaning it's thermal energy is greater.

A driver, traveling at 22.0 m/s, slows down her 2.00 x 103 kg car to stop for a red light. What work is done by the friction for
Artemon [7]
Some work will be done on friction between wheels and road but it is negligible compared to work done on friction on breaks. 

W = Ek = (m*v^2)/2 = 2000*22^2/2 = 1000*22^2 = 484KJ

Because car is not changing its potential energy, there is no work to be done on while changing it which means that all goes on changing kinetic energy (energy of motion)

a family backpacking at Yosemite national park took 5 hours to climb a mountain trail 7.5 km long. what was the family's average
nirvana33 [79]

Answer:

The average speed will be 1.5km/hr .

Explanation:

Distance need to be traveled = 7.5Km

Time taken = 5 hours

Average speed refers to total distance traveled with respect to total time taken .

It can be calculated as given below :

Average speed =total distance /total time taken

Substituting the values we get ,as shown below

Average speed =7.5/5=75/50

Average speed = 1.5 Km/hr

Julian and Joshua each maintain a constant speed as they run laps around a 400-meter track. In the time it takes Julian to compl
Marysya12 [62]

Answer:

the time Joshua travels 1 mile is 12.5 min

Explanation:

Let's start by finding the distance traveled on each lap,

Let's reduce everything to the SI system

    R = 400 m

    d = 1 mile (1609 m / 1 mile) = 1609 m

    L = 2 pi R

    L = 2 pi 400

    L = 2513 m

Let us form a rule of proportions if 2 turns of Julian is 3 turns Joshua, for 1 turn of Joshua how many turns Julian took

    lap Julian = 2/3 turn Joshua

Let's calculate what distance is the same for both of them since they are on the same track

    1 lap = 2513 m

    d. Julian = 2/3 2513 m

    d Julian = 1675 m distance Joshua

Let us form the last rule of three or proportions if 1609 m you travel in 12 min how long it takes to travel 1675 m

    t Julian = 1675/1609 12

    t = 12.5 s

Since this is the distance Joshua travels, this is the time Joshua travels 1 mile
