Answer:
The temperature is always same.
Explanation:
The change of state of matter occurs at the constant temperature, because the heat energy given to the matter is used to change the state in this condition.
So, in the beginning and at the end of the change, the temperature remains constant.
The graph between temperature and time is a straight line parallel to time axis as shown.
Complete Question
A proton of mass mp= 1.67×10−27 kg and a charge of qp= 1.60×10−19 C is moving through vacuum at a constant velocity of 10,000 m/s directly to the east when it enters a region of uniform electric field that points to the south with a magnitude of E = 3.62e+3 N/C . The region of uniform electric field is 5 mm wide in the east-west direction. How far (in meters) will the proton have been deflected towards the south by the time it exits the region of uniform electric field. You may neglect the effects of friction and gravity, and assume that the electric field is zero outside the specified region. Answer is to be in units of meters
Answer:
Explanation:
From the question we are told that
The mass of the proton is
The charge of on the proton is
The speed of the proton is
The magnitude of the electric field is
The width covered by the electric field
Generally the acceleration of the proton due to the electric toward the south (at the point where the force on the proton is equal to the electric force due to the electric field) is mathematically represented as
Substituting values
Generally the time it will take the proton to cross the electric field is mathematically represented as
Substituting values
Generally the the distance covered by the proton toward the south is
Here u = 0 m/s this because before the proton entered the electric field region the it velocity towards the south is zero
So
Substituting values
Record the point at which you caught the ruler, to the nearest cm. Measure from the bottom of your thumb. You can use this table to convert the measurement on the ruler into your reaction time in seconds. The less time it takes you to catch the ruler, the faster your reaction.
Answer:
In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles
