Answer:
94.248 g/sec
Explanation:
For solving the total current of the blood passing first we have to solve the cross sectional area which is given below:
And, the velocity of blood pumping is 30 cm^2
Now apply the following formula to solve the total current
Q = 94.248 g/sec
Basically we applied the above formula So, that the total current could come

Answer:Stretched rubber band with an mass</h2>
Explanation:
Simple harmonic motion requires a restoring force.
Simple harmonic motion should be periodic.
Option A:
When a rubber band is stretched,the internal forces of the rubber band pulls the band inside.So,internal forces are the restoring forces in a rubber band.
The motion is periodic as well since the the rubber band makes to an fro motion expanding ans contracting.
So,this performs SHM.
Option B:
There is no restoring force and no periodicity.
So,this is not SHM.
Option C:
There is no restoring force and no periodicity.
So,this is not SHM.
Option D:
There is periodicity but no restoring force.
So,this is not SHM.
Answer:
a. the motion is both parallel and perpendicular
Explanation:
I did grad point :)
Explanation:
The magnetic force acting on the charged particle in magnetic field is given by :
Here,
q is the charged particle
v is the speed of particle
B is magnetic field
is the angle between the v and B.
The correct statements for the magnetic force are :
- An electric charge moving perpendicular to a magnetic field experiences a magnetic force. In this case,
. It will experience maximum force. - The direction of the magnetic force acting on a moving electric charge in a magnetic field is perpendicular to the direction of motion.
- A magnetic force is exerted on an electric charge moving through a uniform magnetic field.
- The direction of the magnetic force acting on a moving charge in a magnetic field is perpendicular to the direction of the magnetic field.
