The answer to this would be 12N
Answer:
100,800 Jkg
The heat that is used to change the state of a mater is called latent heat.
In this case it is converting ice to water and it is called latent heat of fusion.
It is given by:
Heat = mc
where m is the mass of ice and l is the specific latent heat of fusion of ice.
l = 0.336 MJ
Heat = 0.3 × 0.336 MJ
= 0.3 × 0.336 × 10⁶
= 100,800 Jkg
Answer:
Explanation:
Initial velocity of train u = 3.4 m⁻¹ , Acceleration a = .065 ms⁻² ,
time t = 9.75 x 60 = 585 s.
v = u + at
= 3.4 + .065 x 585
= 41.425 m / s
distance travelled during the acceleration ( s )
s = ut + 1/2 at²
= 3.4 x 585 + .5 x .065 x 585²
= 1989 + 11122.31
= 13111.31 m .
again for slowing process
u = 41.425 m / s
v = u -at
0 = 41.425 - 0.625 t
t = 66.28 s
v² = u² - 2as
0 = 41.425² - 2 x .625 s
s = 1372.82 m
Wrist flexors are the agonist muscles, while wrist extensors are the muscle antagonists. The specific names are the flexor digitorum and the extensor digitorum.
Energy has dissipated into heat
