The correct option is (b) 5n
As a result, there is a net downward force of 5N operating on the object.
The resultant force is the force that results from adding the vector sums of all the forces operating on an item. The combined action of all the acting forces on the object produces the same effect as the resulting force. When determining the resulting force, the direction of the forces must be taken into account.
Given;
The northward force is Fn = 10N
The southward force is Fs = 15N
Required;
The net force on the mobile phone is Fnet = ?N
The object's weight exerts downward pressure, and upward resistance exerts upward pressure. The vector sum of these two forces will be the net force.
Fnet = Fs - Fn (Considering the direction downward as positive)
Fnet= 15N - 10N
Fnet = 5N
As a result, there is a net downward force of 5 N operating on the object.

Answer:
<h2>Yes,</h2>
BMI is a simple indicator of weight for height and can't differentiate between muscle mass and fat mass. So BMI tends to overestimate the health risk for adults with a high muscle mass, such as some athletes, and underestimate the risk for adults with a low muscle mass, as can occur with sedentary lifestyles.

What type of problem it is
Because in a compressed gas particles are closer together, so the potential energy is larger, but since potential energy is negative, then the internal energy is lower
Explanation:
The internal energy of a gas is the sum of the potential energy (PE) and the kinetic energy (KE) of the molecules of the gas:
The kinetic energy of the molecules is directly proportional to the temperature of the gas, T, and it only depends on the temperature: therefore, if we take two gases at the same temperature, then their molecules have the same kinetic energy, no matter if their volumes are different.
The potential energy of the molecules in a gas instead is the energy due to the intermolecular forces between the molecules. The closer the particles are in a gas, the stronger the intermolecular forces, the larger the value of the potential energy; however, potential energy has a negative value. This means that for a compressed gas (particles closer to each other), the potential energy is more negative, and therefore the total internal energy E of a compressed gas is less than that of a rarefied gas.

Here we can say that net speed against the wind is given by
also if it is moving along the direction of wind we will have
now add the above two equations we will have
also we can say
