The First Law describes how an object acts when no force is acting upon it. So, rockets stay still until a force is applied to move them. Likewise, once they're in motion, they won't stop until a force is applied. Newton's Second Law tells us that the more mass an object has, the more force is needed to move it. A larger rocket will need stronger forces (eg. more fuel) to make it accelerate. The space shuttles required seven pounds of fuel for every pound of payload they carry. Newton's Third Law states that "every action has an equal and opposite reaction". In a rocket, burning fuel creates a push on the front of the rocket pushing it forward.
Answer:
Explanation:
Given that
For straight wire
Charge density= λ
For hollow metal cylinder
Charge density=2 λ
We know that electric filed for wire given as
Now the electric filed due to hollow metal cylinder
Now by considering the Gaussian surface r<R then only electric fild due to wire will present.So
At r<R
Answer:
Elements are arranged in the table by increasing atomic number.
Explanation:
In the modern periodic table, each element is represented by its chemical symbol. The number above each symbol is its atomic number.
She misses. She should have accelerated faster in order to get to her target.
