Considering the great topic of thermodynamics (assuming normal atmospheric pressure):
Keep in mind that hotness (temperature) and heat are related but not the same thing. Each time water goes from one state to another, it requires the gain or loss of heat.
In this case the boiling water is gaining heat, the water molecules are vibrating faster with more kinetic energy (energy of motion). The (heat) energy is transferred by the rapid movement of particles colliding with other particles.
Answer:
(a)
67.1 s
(b) 2.5 m
(c) 2.5 m
Explanation:
initial speed, u = 0 m/s
final speed, v = 70 m/s
acceleration, a = 5 m/s2
distance, s = 1800 m
(a) Use third equation of motion
Let the time is t.
Use first equation of motion
v = u + at
134.2 = 0 + 5 t
t = 67.1 s
(b) Use second equation of motion
(c) Use second equation of motion
Answer:
The sun gives off a type of light that carries energy, and the light from the desk lamp does not
Explanation:
I got it off a Quizlet hope this helps!!
Answer:
a - 3
, b - 2
, c-- 2
, d - 1
Explanation:
In this exercise we must relate the different physical processes with the force responsible for the process:
a. Neutron decay
the disintegration of the neutral is an example of the weak interaction
a - 3
b. The Earth pulls the Moon.
In this case as the two bodies and with great mass, the interaction is the gravitational interaction
b - 2
c. gravitational interaction
c-- 2
d. Protons repel other protons in the nucleus.
Since the two particles have a positive charge, the interaction is electromagnetic
d - 1
missing the case of the strong interaction that is responsible for the attraction of proton proton and proton neutron within the nucleus
