It means the speed is constant with a value of 4 units.
Answer:
shielding of electrons
Explanation:
The addition of electrons shells results in the shielding of electrons away from the nucleus, most importantly the nuclear pull resulting from the charge.
- The nucleus pulls electrons to itself due to the net positive charge on it.
- As more electronic shell is added, the effect of the pull weakens outward.
- The inner shell experiences the nuclear pull more than the outer shell electrons.
The effect is responsible for a wide range of properties of elements.
Answer:
Yes, there a link between number of bulbs and current drawn from the power pack.
Explanation:
In an Electrical circuit, we have resistors present in that circuit. These resistors can be connected in two ways.
a) Series connection
b) Parallel connection
There is a link or a relationship between number of bulbs and the current drawn from the power pack. This is because the number of bulbs is equivalent to or equal to the number of resistors.
Hence,
a) In a series connection, the link or relationship between the number of bulbs(resistors) is as the number of light bulbs increases, the current in the power pack (circuit) decreases.
b) In a parallel connection, the link or relationship between the number of bulbs(resistors) is as the number of light bulbs increases, the current in the power pack (circuit) increases.
Answer:
Answer
Explanation:
If the satellite is in perfect orbit around the earth then gravitational pull of the earth on the satellite and moving forward satellite is in perfect balance i.e gravitational pull does not effect the orbit as the velocity of the satellite is good enough to counter the gravitational pull of the earth and inertia makes the satellite move forward with greater velocity, but when its velocity is suddenly reduced, the gravitational pull will counter on the orbiting satellite and it will crash onto the earth.
This is same as in well of death when motorist moves in circular motion inside the well with centripetal and centrifugal forces balanced, suddenly crashes on the ground when velocity of the motorist is not enough to balance forces.
the satellite's mass has no affect on its orbit around the earth rather the mass of the earth is only affecting factor .
Answer:
cause why not.
the layers exist cause theoretically the deeper you go the hotter it gets and different atoms just do stuff
