You should trust the primary source more.
This is because the primary source is make its conclusion from direct observation, while the secondary source is possibly making reference to another secondary source or to another primary.
The primary source should be trusted more because it is from direct observation.
Answer:
Explanation:
If Ig be moment of inertia about an axis through centre of mass and I be moment of inertia through any other axis parallel to earlier axis , then according to theory of parallel axis ,
I = Ig + Md²
where M is mass of the body and d is distance between two parallel axis.
So I is greater than Ig.
The movement of your hand is not considered vibration I think. It's just movement. Music is vibtration, your voice is a vibtration Becasue it makes sound. If I answered this question incorrectly let me know
a = acceleration of the bank cart = 4 m/s²
m = mass of the bank cart = 8000 kg
F = net force on the cart
According to newton's second law , Net force is the product of mass of the object and the acceleration of the object.
Net force = mass x net acceleration
hence Net force acting on the cart is given as
F = ma
F = 8000 x 4
F = 32000 N
hence the net force acting on the cart comes out to be 32000 N
Answer:
arrow coming out of the bar with direction to infinity
Explanation:
In a positively charged bar the electric field lines extend from the bar to infinity, so they are arrow coming out of the bar with direction to infinity, the density of the arrows is indicative of the intensity of the field at the point. Note that the arrows do not cross at any point.
The burden of proof is always considered positive
