Answer:
Explanation:
From the question we are told that:
Radius r=13
Coefficient of static friction \mu=0.67
Given the Centripetal concept
Generally the equation for Velocity v is mathematically given by
The value of the minimum speed (in m/s) for the cyclist to perform the stunt is Given as
Answer:
Call a treatment service. Seek out a healthcare professional. Lastly, report the issue to the local authorities.
Why did I choose these?
You call the treatment services to take care of the person.
You seek out a healthcare professional to get him/her back in shape.
Then you report the issue so that nobody will be endangered by the person that is abusing alcohol. Many accidents occur because of this and that is why you report it.
Explanation:
Answer:
T = 686.7N
Explanation:
For this exercise we will use Newton's second law in this case there is no acceleration,
∑ F = ma
T -W = 0
The gymnast's weight is
W = mg
We clear and calculate the tension
T = mg
T = 70 9.81
T = 686.7N
A change in pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid and to the walls of the container. This is a statement of Pascal's Principle, which is the basis of the hydraulic jack you see lift cars at the garage.
Answer:
Zero
Explanation:
It is given that the charge is uniformly spread at the surface of hollow spherical shells.
There is no charge with in the hollo shell. hence, with zero charge the electric field intensity is also zero.
Thus,
Magnitude of the electric field strength inside the hollow shell at r is zero
