The substance is DNA and it would be found in the nucleus.
2 poles. Induction will make the broken end into a new pole with the opposite charge of the remaining pole
Answer:D
Explanation:
Given
initial velocity of puck A is 
initial velocity of Puck B is 
After collision Puck A started moving in the direction of B and collision is elastic so Puck B remains at the point of collision and Puck A moves with initial velocity of B.
Answer:
The magnetic field circles the wire in a counter-clockwise direction.
Explanation:
This is by using Fleming right hand rule which says If you point your pointer finger in the direction the positive charge is moving, and then your middle finger in the direction of the magnetic field, your thumb points in the direction of the magnetic force pushing on the moving charge.
Answer:
2.177088 * 10^-8 N
Explanation:
solution;
mass(m1) = 1 * 10 kg
mass(m2) = 8 * 102 kg
distance(d) = 5m
universal gravitational constant (G) =6.67 * 10^-11
we know that,
gravitational force = (G*m1*m2)/d^2
=((6.67 *10^-11) *(1 *10)*(8 *102))/5^2
=(5.44272 * 10^-7)/25
=2.177088 *10^-8
Gravitational force = 2.177088 * 10^-8
