Explanation:

pv=nRT

1×20=(273+120)×0.0082×N

2×25=(273+T)×0.082×N

(273+T)=1965/2

T=609.5

A car left Point A at 7:30 am and arrived at Point B, 162 miles away at 10:30 am. What was its average speed in miles per hour?
andre [41]
The formula for average speed is,

S= Total Distance Covered / Total Time Taken

In the given problem, 

The total distance covered is 162 miles.
Since only the times are given, we have to determine how many hours did the car traveled from 7:30am to 10:30am.

To get the number of hours: First, subtract the hours, then the minutes. Hours: 10-7=3 
Minutes: 30-30=0

Therefore,

S = 162miles/3hrs
S = 54miles/hr

The average speed of the car is 54miles/hr.

g A mass of 2.0 kg traveling at 3.0 m/s along a smooth, horizontal plane hits a relaxed spring. The mass is slowed to zero veloc
dezoksy [38]

By the work-energy theorem, the total work done on the mass by the spring is equal to the change in the mass's kinetic energy:

<em>W</em> = ∆<em>K</em>

and the work done by a spring with constant <em>k</em> as it gets compressed a distance <em>x</em> is -1/2 <em>kx</em> ²; the work it does is negative because the restoring force of the spring points opposite the direction in which it's getting compressed.

So we have

-1/2 <em>k</em> (0.15 m)² = 0 - 1/2 (2.0 kg) (3.0 m/s)²

Solve for <em>k</em> to get <em>k</em> = 800 N/m.

A car travels on the entrance ramp to a freeway as it accelerates from 30 mph to the freeway speed of 70 mph for 4.0 s. Suppose
vova2212 [387]

Answer:

a) distance d = 293.36ft

b) acceleration a = 14.67ft/s^2

Explanation:

Acceleration is the change in velocity per unit time.

a = ∆v/t ....1

Given;

Initial velocity vi = 30mph × 5280ft/mile × 1/3600s/h

vi = 44ft/s

Final velocity vf = 70mph × 5280ft/mile × 1/3600s/h

vf = 102.67ft/s

time = 4.0s

From equation 1, acceleration is;

a = ∆v/t = (102.67-44)/4 = 14.67ft/s^2

Distance travelled can be given as;

d = ut + 0.5at^2 .....2

u = 44ft/s

t = 4

a = 14.67ft/s^2

Substituting into the equation 2

d = 44(4) + 0.5(14.67×4^2)

d = 293.36ft
