Answer:
2.kinetic energy because it has the ability to take the students to school.
Explanation:
Energy of a given system due to the virtue of the motion of the given system is known as kinetic energy of the system
now we know that
so kinetic energy depends upon mass of the system and the velocity of the system.
So here since bus is in motion and moving towards the school so the bus along with all the children must have kinetic energy in it
So here correct answer would be
2.kinetic energy because it has the ability to take the students to school.

Answer:
t'=1.1897 μs
Explanation:
First we will calculate the velocity of micrometeorite relative to spaceship.
Formula:
where:
v is the velocity of spaceship relative to certain frame of reference = -0.82c (Negative sign is due to antiparallel track).
u is the velocity of micrometeorite relative to same frame of reference as spaceship = .82c (Negative sign is due to antiparallel track)
u' is the relative velocity of micrometeorite with respect to spaceship.
In order to find u' , we can rewrite the above expression as:
u'=0.9806c
Time for micrometeorite to pass spaceship can be calculated as:
(c = 3*10^8 m/s)
t'=1.1897 μs
Answer:
Explanation:
Given that:
- force applied,
- displacement,
(length of a tennis court)
- time taken for pushing, t = 40 s
Since, work is given by:
Now, power is given as:
Calories consumed is:
Answer:
The value is
Explanation:
From the question we are told that
The wavelength is
The velocity is
The mass of electron is
Generally the energy of the incident light is mathematically represented as
Here c is the speed of light with value
h is the Planck constant with value
So
=>
Generally the kinetic energy is mathematically represented as
=>
=>
Generally the ionization energy is mathematically represented as
=>
