Answer:
ΔT = 59.9 ° C
Explanation:
For this exercise the brake energy is totally converted into heat
Let's calculate the vehicle energy
K = ½ m v²
Let's reduce the units to the SI system
v = 30 mph (1609.34 m / mile) (1h / 3600s) = 13.41 m / s
Em = K = ½ 1200 13.41²
K = 1.079 105 J
All this energy is transformed into heat
Em = Q
The expression for heat is
Q = m 
ΔT
ΔT = Q / m
The specific heat of iron is = 450 J / Kg ºC
ΔT = 1,079 105 / (4.0 450)
ΔT = 59.9 ° C
Answer:
The difference between the Electrolyte and Non-Electrolyte are given in the explanation part.
Explanation:
- ELECTROLYTES are salts or molecules which ionize in solution fully.
- Electrolyte solutions thus conduct electricity readily.
whereas
- NON ELECTROLYTES in water do not dissociate from ions,
- non-electrolyte solutions do not conduct electricity.
It looks correct, but that graph only shows position and time?
Answer:
11.5 meters
Explanation:
73.3°, 12.0m
The y-component is the magnitude of the vector times the sine of the angle measured from the +x axis.
y = 12.0 sin (73.3°)
y = 11.5
The y-component is 11.5 meters.
