Answer:
Explanation:
Given that,
The volume of the cube, V = 24 m³
The density of water, d = 1000 kg/m³
We need to find the buoyant force acting on this cube when it totally submerged in water. The formula for the buoyant force is given by :
Substitute all the values,
So, the required force is equal to 235200 N.

The final speed is:
Answer:
Motion can be described "...in terms of displacement, distance, velocity, acceleration, speed, and time," according to Wikipedia. The main feature that measures motion is momentum or speed.

Answer:</h3>
60 m
<h3>
Explanation:</h3>
<u>Concept Used:</u>
We know that the area under a velocity-time graph represents the Displacement of the body
<u>Displacement in the Last 6 seconds:</u>
To find the Displacement in the last 6 seconds, we will find the area under the graph between x = 4 and x = 10
We can see that the shape formed is a rectangle also shown in the given graph. So, the area of the rectangle is the Displacement of the car in the last 6 seconds
<u>Area of the Rectangle:</u>
From the graph, we know that the rectangle is 10 (m/s) tall and 6 (s) wide
Area of Rectangle= length*Breadth
replacing the values
Area = 10 (m/s) * 6 (s)
Area = 60 m
Hence, the car travelled 60 m in the last 6 seconds of the graph
