The resultant force acting on the shopping cart is 12 N to the right.
This is a scenario related to Newton's Laws. A Free Body Diagram can be utilized to illustrate all the forces acting on the object. There are four forces at play:
- Gravity (g) acting downward.
- Normal force (N) acting upward.
- The force exerted by Sally (Fp) acting to the right.
- Friction force (Ff) acting to the left.
The first two forces (1 and 2) counteract one another as they are equal, while the overall force can be determined by combining forces (3) and (4)
The positive value indicates that the shopping cart is moving towards the right.
Have a good day!
Answer:
Stars generate energy by the process of nuclear fusion.
They are large entities composed of gaseous elements.
The main constituents of stars are hydrogen and helium.
Explanation:
Stars are colossal objects with extensive gravitational forces causing them to contract, which allows fusion to take place: the atomic nuclei in the star's core are drawn very close together due to gravity and elevated temperatures, leading to the fusion reaction. This fusion serves as the energy output for a star.
Conversely, it is true that stars predominantly consist of hydrogen and helium (two hydrogen nuclei can fuse to become helium), which implies that a star is essentially an enormous ball of gas without a solid surface suitable for standing on.
As for the presence of water on a star, it is simply impossible. The extreme temperatures found in stars are far too high for water to exist in any liquid state on their surfaces.
Response:
The car's acceleration will be 
Reasoning:
We are provided with a mass for the ball, m = 1600 kg
The force directed northward is F= 7560 N
The resistance force that counters the car's motion 
Thus, the overall force acting on the car 
According to Newton's second law, we understand that F=ma
Therefore
