Actually Welcome to the Concept of the Treatment.
Basically according to the theory, GAMMA rays are used to treat the cancer.
c.) GAMMA RADIATIONS
Answer:
v = 70 m/s
Explanation:
Range on the cannon ball is given as
here the angle of the projection of the ball is given as 45 degree
now we know that if the velocity of the ball is "v" then its two components will be given as
so here time of flight of the motion is given as
also the range is given as
now plug in all data in this equation
Explanation:
Surface runoff: Excessive water collected on the land due to rains, storms, water melts and from other sources flows over the earth surface.
Transpiration: Moisture in the plants are absorbed by the roots and distributed in all the parts of plant. Moisture present in the underside of the leaves get converted into water vapors and releases in atmosphere
Evaporation : In this process , liquid state of water is converted into gaseous state of water that is water vapors.
Condensation: After evaporation , the water vapors rises up towards the sky. As they rise in the atmosphere the temperature decrease due which these water vapors stars getting converted into small water droplets. These small water drops combines with particles of dust , gas to form clouds
Precipitation: Water released from the clouds in the form of rain.
An elevator has 750,000 J when it is lived 500 meters in the air
Answer: Option D
<u>Explanation:</u>
The expression to find the potential energy completely on the basis of forces that on two objects. It can be written as
Where,
m – mass of object
Acceleration due to gravity =
h = 500 meters
Force = 1500 Newton
As we know, according to Newton second law of motion, the force can be expressed in terms of mass and gravity (F= ma). So, the potential energy can be calculated as
Hence, an elevator has 750,000 J when it is lived 500 meters in the air.
