Answer, gravity helps pull you back down to the earth. At the maximum kinetic energy, the forces acting on the swing is the force of gravity downwards and the normal force from the swing seat on you.

Two moles of He gas are at 25 degrees C and a pressure of 210 kPa. If the gas is heated to 48 degrees C and its pressure reduced

SpyIntel [72]

Answer: $0.0686 m^3$

Explanation:

Given

No of moles=2

$T=25^{\circ}\approx 298 K$

$P_1=210 KPa$

$T_2=48 ^{\circ}\approx 321 k$

$P_2=77.7 KPa$

PV=nRT

Substitute

$77.7\times V_2=2\times 8.314\times 321$

$V_2=0.0686 m^3$

When low on gasoline, is it better to increase or decrease the speed of the vehicle? Explain.

sergiy2304 [10]

Yeah!! It is better to decrease the speed of the vehicle so the ejection of gases would happen in slow manner.... then you can save your gasoline

7. You start to walk toward the east towards home at a constant speed of 4 km/hr. At the same time, Someone else leaves your hom

A) position time graph for both is shown

here one of the graph is of lesser slope which means it is moving with less speed while other have larger slope which shows larger speed

At one point they intersects which is the point where they both will meet

B) Let the two will meet after time "t"

now we can say that

if they both will meet after time "t"

then the total distance moved by you and other person will be same as the distance between you and home

so it is given as

$v_1t + v_2t = d$

$4*t + 28*t = 3.2 km$

$t = \frac{3.2}{32} = 0.1 hr$

so they will meet after t = 6 min

so from position time graph we can see that two will meet after t = 6 min where at this position two graphs will intersect

According to Newton's Law of Cooling, if a body with temperature T 1 is placed in surroundings with temperature T 0, different f

Mila [183]

We can substitute the given values into the equation for T, given the surrounding temperature T0 = 0, initial temperature T1 = 140, constant k = -0.0815, and time t = 15 minutes.

T = 0 + (140 - 0)e^(-0.0815*15) = 140e^(-1.2225) = 41.23°F
