A 5kg backpack will weigh 49 newtons on earth
The total distance that is traveled is 12 inches.
<h3>
What is the distance?</h3>
We know that distance is a scalar quantity. The term distance only has to do with the difference between two points. The direction is not taken into cognizance when we are discussing the distance that has been covered.
As we have said that distance is a scalar quantity, it the follows that the process of obtaining the total distance can only be algebraic given that we could directly add all the distance covered by the ant in order to obtain the total distance of the ant.
Now, we can see that the ant starts at the 17-inch mark, crawls to the 21-inch mark, then moves to the 8-inch mark. The total distance covered is obtained from; (21 - 17) + 8 = 12 inches.

Answer:
Clock on the satellite is slower than the one present on the earth = 29.376 s
Given:
Distance of satellite from the surface, d = 250 km
Explanation:
Here, the satellite orbits the earth in circular motion, thus the necessary centripetal force is provided by the gravitation force and is given by:
where
v = velocity of the satellite
R = radius of the earth = 6350 km = 6350000 m
G = gravitational constant = 
M = mass of earth = 
Therefore, the above eqn can be written as:
Now, for relativistic effects:
Now,
r = R + 250
Ratio of rate of satellite clock to surface clock:
Clock on the satellite is slower than the one present on the earth:
Answer:
Parallel connection is better
Explanation:
Because the voltage across each appliance connected in parallel is same that means if a number of bulbs are connected in parallel then irrespective of the number no bulb will get dim, but in series as the number of bulbs increase the resistance increase voltage
