Answer:
Explanation:
Given
Digit: 1,500,000
Required
Represent using scientific notation
We start by expressing the given digit as a product of 1.5 and a multiple of 10
1,000,000 can be represented as 10⁶
So; the digit becomes
<em>Hence, the scientific notation of 1,500,000 is 1.5 * 10⁶</em>
Answer:
Blue is reflected and pink is absorbed
Explanation:
Reflection involves the wave bouncing back from the surface while absorption involves the wave passing through the surface.
Answer: A surface wave is a wave that moves along the interface of two different materials, like air and water.
In order to find the our own velocity with respect to land,we need to apply the theory of relative velocity.
Now consider the velocity of the ship traveling towards the north with respect to land as A.Consider our own velocity headed northwards as B.
The relative velocity is the velocity that the body A would appear to an observer on the body B and vice versa.
In this case the relative velocity would be arrived by summing up our velocity with the velocity of the ship as the object (I) is travelling in the ship.
Relative velocity = Velocity of Body A+ Velocity of Body B.
Velocity of the ship traveling towards the north with respect to land(A)= 13.0m/s. (Given)
Our own velocity headed northwards(B)= 2.8 m/s.
Relative velocity = Velocity of Body A+ Velocity of Body B.
Relative velocity= 13.0 + 2.8 = 15.8m/s.
Thus our own velocity with respect to the land is 15.8 m/s.
The small space about the piston in which fuel is burned is called the combustion chamber.
