the following equation is an example of alpha decay
Answer:
Explanation:
Given
Velocity of bat
Frequency of sound
velocity of sound
using Doppler Effect apparent frequency is given by
where
apparent frequency
v=velocity of sound in the given media
velocity of source
velocity of observer
here velocity of source is zero
as source is travelling towards source thus
Answer B is the correct answer
We know that kinetic energy , where m is the mass of object and v is the velocity of object.
In this case only velocity is the variable, mass remains constant.
So point having higher velocity has higher kinetic energy.
When it leaves the racket, the ball will be having a certain height, but just before it reaches the ground it will not having any height. So maximum velocity of ball is at that time when it reaches just above the ground.
So option B is the correct answer.
Answer:
(a) 2.5 cm
(b) Yes
Solution:
As per the question:
Mass of Uranium-235 ion, m =
Mass of Uranium- 238, m' =
Velocity, v =
Magnetic field, B = 0.250 T
q = 3e
Now,
To calculate the path separation while traversing a semi-circle:
The radius of the ion in a magnetic field is given by:
R =
Now,
By putting suitable values in the above eqn:
(b) Since the order of the distance is in cm, thus clearly this distance is sufficiently large enough in practical for the separation of the two uranium isotopes.
Air mass abbreviated Cp has cold temperature and dry moisture.
Explanation:
Air mass abbreviated Cp means regions of continental polar or continental arctic. So mostly in the northern hemisphere where the temperature is very low like in Alaska, the mass of air is termed as Cp. At those low temperature, the temperature is very cold and so the moisture present in the air in those regions will be dry in nature. Mostly, they originate in the northern hemisphere like in canada, Alaska and then they will spread toward the south and east directions.
So they air masses present in those cooler regions are extremely cold and has dry moisture.
