Answer:
S = V t where S is the horizontal distance traveled
1/2 g t^2 = H where H is the vertical distance traveled
t^2 = 2 H / g
V^2 = S^2 / t^2 = S^2 g / (2 H) combining equations
tan theta = H / S
V^2 = S g / (2 tan theta)
Using S = L cos theta
V^2 = L g cos theta / (2 tan theta)
Giving V in terms of L and theta
Answer:
The value is 
The force will be outward
Explanation:
From the question we are told that
The diameter of the disk is 
The external pressure on Mars is 
From the question we are told that
Internal pressure = External pressure
Generally the external Force on earth is
Here 
is the atmospheric pressure with value 
So
=> 
=> 
Generally the external Force on Mars is
=> 
=> 
Net force is mathematically represented as
=> 
=> 
converting to pounds
=>
Given that that the value is positive then the force will be outward
Your pendulum does a complete swing in 1.9 seconds. You want to SLOW IT DOWN so it takes 2.0 seconds.
Longer pendulums swing slower.
You need to <em>make your pendulum slightly longer</em>.
If your pendulum is hanging by a thread or a thin string, then its speed doesn't depend at all on the weight at the bottom. You can add weight or cut some off, and it won't change the speed a bit.

Absolute: harrison's birth, the building of jasmine house, and the extinction of the triceratops
Explanation: plato
Answer:
1) The plane of the loop is perpendicular to the magnetic field.
2) The magnetic flux is independent of the orientation of the loop.p
Explanation:
The flux is calculated as φ=BAcosθ. The flux is therefore the highest when the magnetic field vector is perpendicular to the plane of the loop We can also deduce that the flux is zero when there is no magnetic field part perpendicular to the loop When the angle reaches zero, the flux is in the limit because when the angle becomes zero, the cos is the maximum.
