The convection going on with the magma in the asthenosphere
I think it would be the fourth one
Answer:
Explanation:
Two
The nuclear force does not work
under long distances
is greater in strength the the electomagnetic force when the distances are small.
I'm not sure what D means.
I think it does depend on charge.
You have to choose D but this is a notes question and I'm not at all certain of the answer.
One
If its number is 19, the the number of protons = the number of electrons = 19
Answer B
Answer:
B. q = 2.5 x 10^-1 C
Explanation:
Formula: E = F/q
Given information:
E = 40 N/C
F = 10N
--> q = F/E = 10/40 = 0.25 C
or q = 2.5 x 10^-1 C
Answer:
Explanation:
For answer this we will use the law of the conservation of the angular momentum.
so:
where is the moment of inertia of the merry-go-round, is the initial angular velocity of the merry-go-round, is the moment of inertia of the merry-go-round and the child together and is the final angular velocity.
First, we will find the moment of inertia of the merry-go-round using:
I =
I =
I = 359.375 kg*m^2
Where is the mass and R is the radio of the merry-go-round
Second, we will change the initial angular velocity to rad/s as:
W = 0.520*2 rad/s
W = 3.2672 rad/s
Third, we will find the moment of inertia of both after the collision:
Finally we replace all the data:
Solving for :
