Answer:
Product,
P = 639619.091888
Explanation:
In this case, we need to find the product of two numbers. These are as follows :
On doing calculation, we get the product of two numbers as :
P = 639619.091888
In scientific notation the product of two number is given by :
Hence, this is the required solution.
Displacement measures how far it is from the starting point and the final location, which in this case is the distance between Honolulu and Los Angeles. The difference between distance and displacement is that distance measures how far the object actually travels. For example, the airplane may not fly in a straight line and it may have detours, making the distance much greater than the displacement.
On the other hand, the plane could fly at different speeds at different periods of time. It will be so much more complicated if we have to calculate it. That's why this question only asks you to calculate the average velocity of the plane, ie.
So, we have
the required average velocity =
= 511.6 miles/hour
Hope this helps!
Answer:
178.4 times
Explanation:
We have Newton formula for attraction force between 2 objects with mass and a distance between them:
where is the gravitational constant on Earth.
is the masses of the 2 objects. and R is the distance between them.
From here we can calculate the ratio of gravitational force between the moon and the sun
We can divide the top and bottom by G and M
So the gravitational force of the sun is about 178 times greater than that of the moon to an object on Earth
A. Horizontal component: 7.3 m/s
Explanation:
The horizontal component of the velocity is given by:
where
is the magnitude of the initial velocity
is the angle of the initial velocity with respect to the ground
Substituting numbers into the equation, we find
B. Vertical component: 14.3 m/s
Explanation:
The vertical component of the velocity is given by:
where
is the magnitude of the initial velocity
is the angle of the initial velocity with respect to the ground
Substituting numbers into the equation, we find
