The climber move 0.19 m/s faster than surfer on the nearby beach.
Since both the person are on the earth, and moves with the constant angular velocity of earth, however there linear velocity is different.
Number of seconds in a day, t=24*60*60=86400 sec
The linear speed on the beach is calculated as
V1=
Here, t is the time
Plugging the values in the above equation
V1=
=465.421 m/s
Velocity on the mountain is calculated as
V2=
Plugging the values in the above equation
V2=
=465.61 m/s
Therefore person on the mountain moves faster than the person on the beach by 465.61-465.421=0.19 m/s
We can solve the problem by using Kepler's third law, which states:
where T is the period of revolution of the Moon around the Earth, G is the gravitational constant, M the Earth's mass and r the average distance between Earth and Moon.
Using the data of the problem:
We can re-arrange the equation and find the Earth's mass:
Answer:
Competitive forces model
Explanation:
A Competitive forces model is the important tool which is used in the strategic analysis to determine the competitiveness in an organization. The model is commonly known as the "Five Force Model of Porter", which includes five forces — intensity of a rivalry, the bargaining ability of the buyers, threat of the potential new entrants, the bargaining power of a supplier, and the threat of substitute goods or services.
It affects the organizations's ability to compete as well as the strategy to succeed.
The question seems to be incomplete. However, I can think of a possible logical question this problem could have. The equation for the maximum height attained by any object thrown upwards is:
H = v²/2g
I think the question would be determining the gravity in Io assuming that the initial velocity of the lava is the same. Then, the solution is as follows:
Let's use the other volcano to find v.
1.89×10⁵ m = v²/2(1.72 m/s²)
Solving for v,
v = 806.325 m/s
So, we use this to find g in Io.
2×10⁵ m = (806.325)²/2(g)
Solving for g,
<em>g = 1.6254 m/s²</em>
The best improvement to these instructions that Keisha can make
immediately and easily is to describe where the instructions start from.
Does the route start from Keisha's house ? From her friend's house ?
From my house ?
Knowledge of the coordinate reference frame makes a big difference,
and it's essential.
