Discuss gravitational force and strong nuclear force. Describe at least two ways that they are alike and two ways that they are different.
Answers
Strong nuclear force is the colossal force possessing protons together in an atomic nucleus.
Alike:
They are both attractive forces.
They are both charge-independent
Different:
Vigorous nuclear force only applies to protons while gravity applies to all matter.
Gravity occurs on all levels of space while the robust nuclear force only occurs at the sub-atomic level.

The acceleration of the sled is 2.2 m/s^2.
To determine the acceleration of the sled, we can use Newton's second law of motion which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration: F = m * a. Rearranging the formula, we have a = F / m. Plugging in the given values, we get a = 540 N / 250 kg = 2.16 m/s2. Therefore, the correct answer is B. 2.2 m/s2.

Answer:
Car C
Explanation:
It is given that,
Five race cars speed toward the finish line at the Jasper County Speedway. The mass of each car has same mass. The speed of all cars are given as :
Car A = 890 m/s
car B = 850 m/s
Car C = 790 m/s
Car D = 895 m/s
Car E = 870 m/s
The distance is constant because the finish line is same for all cars. The speed of an object is given by the total distance covered divided by total time taken i.e.
Where
d = distance
t = time required by the car to come to a full stop
So, time taken is inversely proportional to the speed of the car. The car having less speed will take maximum time to come to stop. Hence, car C will require longest time to come to a full stop.
Answer:
Car D
Explanation:
The mass of the car is given the same. The initial velocities are also given. eventually all the cars come to a stop. The finish line would be crossed first by the fastest car. But If all the cars decelerate at the same rate then, we can find out the time taken to come to a full stop by first equation of motion,
final velocity, v = 0
if a is same for all cars.
Car D has maximum speed ( 895 m/s). So, Car D will take the maximum time to come to a stop.
