Answer:
(a) 
(b) 
Given:
Time period of Pulsar, 
Equatorial radius, R = 15 Km = 15000 m
Spinning time, 
Solution:
(a) To calculate the value of the centripetal acceleration, 
on the surface of the equator, the force acting is given by the centripetal force:
(1)
where
(2)
Now, from (1) and (2):
(b) To calculate the tangential acceleration of the object :
The tangential acceleration of the object will remain constant and is given by the equation of motion as:
where
u = 
To solve this problem, it is necessary to apply the concepts related to Work according to the Force and distance, as well as the concepts related to energy lost-or gained-by heat. Mathematically the energy corresponding to heat is given as:
Where,
m = mass
= Specific heat
= Change in Temperature
At the same time the Work made by the Force and the distance is given as:
As the force is applied at an angle of 30 degrees, the efficient component would be given by the vertical then the work / energy would be determined as:
Now this energy is used to heat the aluminum. We can find the change at the temperature as follow:
Therefore the correct answer is B.
Answer:
Low satellite has high orbital velocity
Explanation:
let v be the orbital speed of the satellite orbiting at a height h is given by
where, M be the mass of planet, r be the radius of planet and h be the height of planet from the surface of planet.
here we observe that more be the height lesser be the orbital velocity.
So, a satellite which is at low height has high orbital velocity.
Hi!
Here’s your answer:
What happened to the combined energy of the two sleds when they collided? It changed forms into another energy C. Because energy is conserved, the “lost” energy has actually been changed into other forms.
Hope this helps have a good day!!<3
ANSWER - (1) are constantly moving (2) have volume (3) have intermolecular forces (4) undergo perfectly elastic collisions (5) have an average kinetic energy proportional to the ideal gas’s absolute temperature
