Distance: The total distance traveled is the sum of the individual distances traveled in each direction. In this case, you moved 25 meters North and then 50 meters West. So, the total distance is:
Distance = 25 m (North) + 50 m (West) = 75 meters
Displacement: Displacement is the straight-line distance from the starting point to the final point, taking into account both the distance and direction. To calculate the displacement, you can use the Pythagorean theorem because the motion is in perpendicular directions (North and West).
Displacement = √((25 m)² + (50 m)²)
Displacement = √(625 m² + 2500 m²)
Displacement = √(3125 m²)
Displacement = 55.9 meters (rounded to one decimal place)
-the total displacement is approximately 55.9 meters in a direction that is between North and West.
The acceleration of the object is 0.3 m/s² when the force applied on the object.
Physics defines force as the push or pull that modifies the velocity of a massed object. An external force is a force that can change a body's resting or moving condition. There is a magnitude and a direction to it.
You may measure the Force using a spring balance. The unit of force in the SI is the Newton.
According to Newton's second law of motion: force applied on any object is equal to the change in momentum of the object per unit time.
Hence, F = dP/dt
F = m dv/dt = ma
So, force = mass × acceleration
Given force applied on the object = 3 N
Mass of the object = 10 kg
Hence, the acceleration of the object is = Force ÷ mass
= ( 3 ÷ 10) m/s²
= 0.3 m/s²

Explanation:
The autonomic nervous system has two components, the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system functions like a gas pedal in a car. It triggers the fight-or-flight response, providing the body with a burst of energy so that it can respond to perceived dangers.
The fight-or-flight response is a physiological reaction triggered by a perceived threat or danger. It prepares the body for action by releasing stress hormones and increasing heart rate. This response helps individuals to either fight the threat or flee from it.
The fight-or-flight response is a physiological reaction that occurs in response to a perceived threat or danger. When triggered, the body releases stress hormones like adrenaline and cortisol, which prepare the body for action.
This response can help increase heart rate, dilated pupils, and redirect blood flow to the muscles, enabling the individual to either fight the threat or flee from it.

Answer:
Satellites are placed into orbit at least 150km above Earth's surface to ensure that they remain above the atmosphere.
The velocity required to keep a balance between the inertia of the motion of the satellite and the earth's gravitational pull, which is called the orbital velocity, essentially depends on its distance above the surface of the Earth. The higher this distance, the longer the satellite will stay in the orbit. Otherwise it might run into the atmosphere and could get burnt up there.
