Answer:
v = \sqrt{Rg}
Explanation:
As the car just maintain the contact at the top point of the circular track, it means the weight of the car is just balance by the centripetal force acting on the track.
Let v be the speed of the car.
M g = Mv^2 / R
g = v^2 / R
v^2 = R g
Hey there!
Your answer is C, for circuit- ironic.
Here's why:
A circuit is made of things like insulators, transistors, and conductive material, all in a loop for electricity to travel through. The loop has to be intact and be able to let electricity pass through to do its job.
Therefore, it's not the same as a conductor or insulator, and it can't be broken.
Hope this helps!
Answer:
the ambulance have to travel 4507.847 feet to get to the accident
Explanation:
Let D represent position of ambulance
Let C represent position of accident scene
The situation is represented in the below attached figure
In the figure we have
AB = 4000 feet
Thus in triangle ABC we have
In triangle ABD we have
Thus the distance between the ambulance and accident scene will be 14925.20-10420.356 = 4507.847 feet
Answer:
O Hooke and Leeuwenhoek
Explanation:
O Hooke and Leeuwenhoek discovered the existence of micro organisms between 1665 and 1683
Explanation:
As w = 2000π
2πf= 2000π
f= 1000Hz
speed = wavelength × f= w/k
wavelength = 2000π/ (0.5× 1000)
= 4π
or
12.57
