Ответ:
Solution:
Q=c*m*change in temperature
10000=x*2*10
x=500
Specific Heat Capacity of the Iron is 500 J/kg*C
Ответ:
heat capacity = 500J/kg• K
Explanation:
q = m•c•ΔT
q = heat energy
m = mass
c = heat capacity
ΔT= change in temperature
10KJ = 10000 J
10000 J = 2kg • c • 10 Cº
divide each side by 20
500J/kg• K = heat capacity
Ответ:
786.6 N
Explanation:
mass of car, m = 912 kg
initial velocity of car, u = 31.5 m/s
final velocity of car, v = 24.6 m/ s
time, t = 8 s
Let a be the acceleration of the car
Use first equation of motion
v = u + a t
24.6 = 31.5 + a x 8
a = - 0.8625 m/s^2
Force, F = mass x acceleration
F = 912 x 0.8625
F = 786.6 N
Thus, the force on the car is 786.6 N.
