Answer:
Weight and reaction.
Explanation:
With respect to Newton's third law of motion, action and reaction have equal magnitude but acts in opposite direction.
Thus, the brick of mass 10 kg has its weight (due to gravitational pull of the earth), which acts downwards through its center of mass. This makes the scale to produce an opposing force of equal magnitude, which acts upwards. These two forces acting in opposite directions balancing each other.
The two forces acting on the brick are: its weight and the reaction from the scale.
Answer:
Explanation:
velocity=s/t
given distance is 480 km we have to convert it into meter because the unit of distance is meter
1 km=1000 m
480 km=480000 m =4.8*10^5
1 hour= 3600 s
12 hour =43200 s
now velocity=s/t
v=4.8*10^5/43200
v=11.11 m/s
Erything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

<u>Given: </u>
- The mass of a stuffed bear = 200 grams = 0.2 kg.
- The mass of a boy = 25 kg.
- The mass of a girl = 20 kg.
- A boy pulls to the right with a 15 N force.
- A girl pulls to the left with a 17 N force.
<u>Question:</u>
What the acceleration of the bear is?
This is the case for implementing Newton's second law, i.e., 'the resultant force is proportional to the acceleration'. If we also use SI units then 'the resultant force is equal to the product of the mass and the acceleration'.
- The net force, i.e., is the resultant of all forces acting on an object, measured in newtons (kgm/s²).
- The mass measured is kilograms.
- The acceleration measured in m/s².
Let's calculate the net force.
Referring to the horizontal axis marked a positive to the right, then
A negative sign indicates that the bear is moving to the left.
We continue to calculate the bear's acceleration. Remember, the mass that is applied is the mass of the bear that is accelerating.
Thus, the magnitude and direction of the acceleration is

Answer:
it can cause huricans and flooding
Explanation:
Storm surge is the rising of the sea level due to the low pressure, high winds, and high waves associated with a hurricane as it makes landfall. The storm surge can cause significant flooding and cost people their lives if they're caught unexpected
