Answer:
The speed of the resistive force is 42.426 m/s
Explanation:
Given;
mass of skydiver, m = 75 kg
terminal velocity,
The resistive force on the skydiver is known as drag force.
Drag force is directly proportional to square of terminal velocity.
Where;
k is a constant
When the new drag force is half of the original drag force;
Therefore, the speed of the resistive force is 42.426 m/s
Answer:
d) business intelligence
Explanation:
Business intelligence refers to applications and technologies that are used to gather, provide access to, and analyze data and information to support decision-making efforts. Business Intelligence uses technologies for the data analysis of business information to make strategic decision for enterprises. Common functions of business intelligence technologies include reporting, online analytical processing, analytics, data mining, process mining, complex event processing, business performance management, benchmarking, text mining, predictive analytics and prescriptive analytics.
A pool ball hits a second pool ball with equal mass. The first pool ball comes to a complete stop, while the second pool ball rolls away.
The second pool ball's velocity will be the same as the first pool ball's velocity was.<em> (B)</em>
And that's literally 'velocity', not just speed. The second ball must take off from the collision with the same speed AND in the same direction as the first ball.
That's the only way that momentum can be conserved !
Complete Question
The complete question is shown on the first uploaded image
Answer:
Explanation:
From the question we are told
The amplitude of the lateral force is
The frequency is
The mass of the bridge per unit length is
The length of the central span is
The oscillation amplitude of the section considered at the time considered is
The time taken for the undriven oscillation to decay to of its original value is t = 6T
Generally the mass of the section considered is mathematically represented as
=>
=>
Generally the oscillation amplitude of the section after a time period t is mathematically represented as
Here b is the damping constant and the is the amplitude of the section when it was undriven
So from the question
=>
=>
=>
=>
Generally the amplitude of the section considered is mathematically represented as
=>
=>
=>
=>
