Answer:
Magnesium atomic no. = 24,25,26. These are the two elements which have same atomic no
Explanation:
Answer:
K = -½U
Explanation:
From Newton's law of gravitation, the formula for gravitational potential energy is;
U = -GMm/R
Where,
G is gravitational constant
M and m are the two masses exerting the forces
R is the distance between the two objects
Now, in the question, we are given that kinetic energy is;
K = GMm/2R
Re-rranging, we have;
K = ½(GMm/R)
Comparing the equation of kinetic energy to that of potential energy, we can derive that gravitational kinetic energy can be expressed in terms of potential energy as;
K = -½U
Explanation:
Current output at the battery will be current of entire circuit, while the current through each bulb in the parallel circuit is the total current circuit.
So, current output through power supply is i and current through each component be 
considering only three component.
Then in a parallel circuit
A. A flood would have the most positive effect
The force needed to accelerate a vehicle with a mass of 1000kg at a rate of 5m/s2 would be 5000
