Carbon2 hydrogen hydroxide oxygen V carbon dioxide 4 H2O three
The answer is b. because the heat is even on both when the stream is gone
When kinetic energy of the particles get heated the motion of the particles increases as the particles become more energetic.
When particles are heated up, space is being created. The atoms started to get "overly excited" and started to move faster than they usually do. When this happens, energy is released in the form of heat, light or etc. Because of this, kinetic energy increases and atoms colliding with each other happens more often.
There are three basic types of experimental research designs . ... True experimental designs are characterized by the random selection of participants and the random assignment of the participants to groups in the study. The researcher also has complete control over the extraneous variables.
Answer:
27.39 m/s
Explanation:
From the question given above, the following data were obtained:
Deceleration (a) = –3 m/s²
Distance (s) = 125 m
Final velocity (v) = 0 m/s
Initial velocity (u) =?
The initial velocity (u) of the car can be obtained as follow:
v² = u² + 2as
0² = u² + (2 × –3 × 125)
0 = u² + (– 750)
0 = u² – 750
Collect like terms
0 + 750 = u²
750 = u²
Take the square root of both side
u = √750
u = 27.39 m/s
Thus, the initial velocity of the car was 27.39 m/s
