Answer:
Explanation:
Potential energy and kinetic energy
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
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 measurement has two parts: a value and a unit. a fixed amount of something, like a centimeter (CM) of distance.
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
