Answer:
14 m/s
18 m/s
22 m/s
Explanation:
The car is moving at constant acceleration, so we can find its velocity at time t using the equation:
where
u = 10 m/s is the initial velocity
is the acceleration
t is the time
Substituting the different times, we find:
At t = 2 s:
At t = 4 s:
At t = 6 s:
The answer is D) Cyclones. I am 100% sure on this one, so yeah. Hope this helps, and good luck. :D
Answer:
Mechanical energy is the total energy of the body is made up of scientific energy and potential synergy, these two can be converted into one another without needing help.
The most determining factor of kinetic anergy is speed since it is squared
Explanation:
Mechanical energy is the total energy of the body is made up of scientific energy and potential synergy, these two can be converted into one another without needing help. Kinetic energy is the energy of movement, increasing the speed of the body increases the kinetic energy.
The energy powers an energy from the system configuration when changing to a lower energy configuration this is converted into mechanical energy.
The most determining factor of kinetic anergy is speed since it is squared
Answer: The observation that all objects that have mass attract each other
The question is incomplete,so the complete question is as follows:
According to Einstein, increasing the brightness (or intensity) of a beam of light without changing its color will increase (circle all that apply):
A) the number of photons per second traveling in the beam.
B) the energy of each photon.
C) the speed of the photons.
D) the frequency of the light.
E) the wavelength of the photons
Answer:
A)
Explanation:
According to Einstein, an increase in the intensity or brightness of light beam will increase the number of photons over a given time interval.
It means that the energy emitted will depend on the energy of individual photon rather than the intensity of the incoming light.
Hence, the correct option is "A)"
