Temperature has a(n) _____ effect on the pressure and volume of a gas.

Fiesta28 [93]

Temperature has a direct effect on the pressure of a gas.

If the pressure is constant and the gas is free to fill more
or less space, then temperature also has a direct effect on
the volume of the gas.

2. A new racecar track is being created, and the owners want the cars to complete 10

jeka57 [31]

Answer:

0.45 miles

Explanation:

since, car will be running on the edge of track, distance covered in one lap by car will be equal to circumference of track.\

we will use value of pi as 22/7

Circumference for any circular shape is given by $\piD$ $\pi D$

Hence, in one lap $\pi D$ distance will be covered

in 7 laps $7 \pi D$ distance will be covered.

but is given that 7 laps should be equal to 10 miles

so 10 miles will be equal to $7\pi D$

$7\pi D= 10 \ miles\\=> 7*(22/7)* D= 10 \ miles\\=> 22D = 10 \ miles\\=> D = 10/22 \ miles\\=> D = 0.45 \ miles$

Thus, diameter of track will be 0.45 miles to meet the requirement.

41. City A lies 30 km directly south of city B. A bus, beginning at city A travels 50 km at 37° north of east to reach city C. H

Nana76 [90]

Answer:

B) 40 km West

Explanation:

Let position of B is origin so with respect of City B the position of A is given as

$r_A = 30 km$ south of city B

now Bus starts from City A and travels a distance of 50 km at 37 degree North of East to reach city C

so it is

$r_{CA} = 50(cos37\hat i + sin37 \hat j)$

$r_{CA} = 40\hat i + 30\hat j$

now the position of C is given with respect to A

in order to find the position of C with respect to B we can say

$r_C = r_{CA} + r_A$

$r_C = 40\hat i + 30\hat j + (-30 \hat j)$

$r_C = 40 \hat i$

so in order to reach at city B from city C bus has to travel 40 km towards West

if a runner's is 400 w as she runs,how much chemical energy does she convert into other forms in 10.0 minutes?

Fiesta28 [93]

Explanation:

The runner runs for a total time of

\Delta t=10.0 min= 600 sΔt=10.0min=600s

The energy converted by the runner during this time is equal to the power of the runner times the total time:

E=P \Delta t=400 W \cdot 600 s =2.4 \cdot 10^5 JE=PΔt=400W⋅600s=2.4⋅10
