The number of protons always differs in atoms of different elements.
Answer:
Average Velocity = - 1.22 cm/s = - 0.0122 m/s
Explanation:
The average velocity of an object is defined as the ratio of the total distance traveled by the object to the total time taken by the object to cover the distance. Therefore, the average velocity of an object can be found by the following formula:
Average Velocity = Total Distance Covered/Total Time Taken
Average Velocity = (Final Position - Initial Position)/Total Time Taken
Average Velocity = (3.7 cm - 6.5 cm)/(2.3 s)
Average Velocity = (- 2.8 cm)/(2.3 s)
<u>Average Velocity = - 1.22 cm/s = - 0.0122 m/s</u>
here, the negative sign indicates the direction of the velocity or the movement of the object is leftwards or towards the origin approaching from right.
The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius
Answer:
8.97 days
Explanation:
Assuming we are asked what will be the period of revolution, this planet's year, in Earth days?
The period of revolution T is given as

here, r= distance between planet and its sun which is same as distance between Earth-Sun = 
g= acceleration due to gravity = 
therefore,

=775580 seconds
= 8.97 days
