200 N, that is if the force is balanced and the wall doesn't move
Momentum = mass x velocity
= 1500 x 8
= 12000 kg m/s
Answer:
The potential energy when it reads 40 N is 
Explanation:
From the question we are told that
The lowest reading of the spring balance is 0 N and this is at 0 cm = 0 m
The height reading of the spring balance is 60 N and this is at 20 cm = 0.20 m
Generally the length corresponding to the reading of 40 N is mathematically represented as
=> 
Generally the potential energy is mathematically represented as
Here
So
=>
Answer:
Explanation:
The distance will be the total distannce covered during the journey.
If you move 3 meters East and move 4 meters north, then the distance will be calculated as;
Distance = distnace through East+distance through north
Distance = 3m + 4m
<em>Distance = 7m</em>
Displacement is the distance covered in a specified direction. It is the shortest distance covered by me. This can be gotten using the Pythagoras theorem.
d² = 3²+4²
d² = 9+16
d² = 25
d = √25
d = 5m
<em>Hence the displacement of the object is 5metres</em>
As opposed to what is mentioned as the sea breeze, what was being asked to describe is what is known to be as land breeze. If the sea breeze is a wind that comes from the sea to the land, then the land breeze is the wind that comes from the land going to the sea. The same concept applies. What happens is that when the warmer air over the ocean rises and the cooler air over land rushes in to replace the warmer air, the movement of the air comes at still and creates the breeze. The directions of the wind would also go towards the sea.
