Answer:
Distance traveled will be
Explanation:
We have given speed of the light
We have to find the distance traveled by light in 1 year
We know that 1 year = 8760 hour
And 1 hour = 60×60 = 3600 sec
So 1 year
We know that distance = speed × time
So distance traveled by light in one year
We have to fond the distance in km
As we know that 1 km = 1000 m
So
Radio messages will travel approximately 9.46 x 10^12 kilometers in exactly one year.
Radio waves travel at the speed of light which is approximately 3.00 x 108 m/s.
To find out how many kilometers radio messages will travel in exactly one year, we need to first convert the speed of light into kilometers per second.
Since there are 1000 meters in a kilometer, we divide the speed of light by 1000 to convert from meters to kilometers. Then, we multiply this value by the number of seconds in a year (365 days x 24 hours x 60 minutes x 60 seconds) to get the total distance traveled in kilometers.
In summary, radio messages will travel approximately 9.46 x 1012 kilometers in exactly one year.

Answer:
Therefore, a. chemical energy plant store when light is transformed during photosynthesis.
Explanation:
Photosynthesis is the process plants and some algae use to convert light energy to chemical energy stored as sugar within chloroplasts .
Photosynthesis is 6CO2 + 6H20 + light energy = glucose + 6 oxygen.
Photosynthesis is divided into two main stages: light reaction and dark reaction. The light reaction converts light energy into adenosine triphosphate,
B.The small mass accelerates faster
C.Both accelerate at the same time
As per the question the mass of the object is given as 70 kg.
The height of the object from ground is 8 m.
We are asked to calculate the potential energy of that object.
The potential energy of a object is the energy gained by the body due to its position or configuration. The energy due to the position of object from the surface is called gravitational potential energy .
If a body of mass m is at a height of h from the ground,then its potential energy is calculated as -
potential energy
where g is the acceleration due to gravity.
we have been given h= 8 m and m= 70 kg
we know that acceleration due to gravity g =9. 8 m/s^2
⇒
=5488 Joule
Here Joule is the unit of energy.
