the temperature of monoatomic gas was increased from t1=27c to t2=177c. by how many times the internal energy of the gas increas
Romashka [77]

The internal energy increases 1.5 times

Explanation:

the internal energy of a mono atomic gas is given by E= 3/2kT

T1= 27⁰C= 27+273=300 K

T2=177⁰C= 177+273=450 K

E1= 3/2 k (300)

E2=3/2 k (450)

so E2/E1=[3/2 k (450)][3/2 k (300)]

E2/E1=450/300

E2= 1.5 E1

so the internal energy increases by a factor of 1.5

The two identical trucks are traveling in opposite directions, and truck B is carrying a heavy load. (a) Will the magnitude of t
Dmitry [639]

Answer:

The force exerted on truck A by truck B will definitely be greater than the magnitude of the force exerted on truck B by truck A

Explanation:

According to the concept of momentum

Momentum is the product of a body's mass and its velocity.

Yes both trucks are the same, but truck B is carrying a heavy load which gives it more momentum that A, actually momentum is a function of mass

Momentum M=mass(m) x velocity (v)

A superman cyclist rode a bike uphill at 20 miles/hour for two hours. To sustain this constant speed the cyclist was exerting 50
NeX [460]

Answer:

1.056 x 10⁷ lb-ft

Explanation:

v = Speed of the bike = 20 mph

t = time of travel = 2 h

d = distance traveled by cyclist

Distance traveled by cyclist is given as

d = v t

d = (20) (2)

d = 40 miles

We know that, 1 mile = 5280 ft

d = 40 (5280) ft

d = 211200 ft

F = force applied by cyclist = 50 lb

W = work done by cyclist

Work done by cyclist is given as

W = F d

W = (50) (211200)

W = 1.056 x 10⁷ lb-ft
