Answer:
You could put over six planets the size of Mars inside the Earth. The largest planet in our Solar System, Jupiter's size is astounding. Jupiter has a volume of 1.43 x 1015 cubic kilometers. To show what this number means, you could fit 1321 Earths inside of Jupiter
Explanation:
Answer: Yes.
Explanation:
Assuming Earth and Moon are isolated is space, it is possible to have a point where Earth and Moon will pull at an object with equal force.
That point will be closer to the Moon than the Earth because Moon's gravitational field strength is weaker than Earth's gravitational field strength.
The mathematical relationship between force and extension for a spring is F = -kx , where F is the restoring force, k is the spring constant and x is the extension. If a box that weighs 40 N is hung from a spring of content 400 N/m, then the extension is equal to x = -F / k = -400 / 40 = -10 cm. The negative sign simply shows the extension and restoring force are in opposite directions. The answer is 10 cm.
Part a is simply mass*gravity. Tension=ma
Part b Tension= 50kg(10m/s+5.0m/s) = 750N
The correct answer to the question is direct current i.e a battery produces direct current which is the current that flows in only one direction.
EXPLANATION:
Before coming into any conclusion, first we have to understand the types of current. There are generally two types of current which are known as direct current and alternating current.
Direct current:
A direct current is the current which moves in one direction only. It may be a steady current or a pulsating direct current.
A steady current is a time independent current i.e its magnitude is constant with time. It is also known as a stationary current. For instance, the current flowing through a battery.
A pulsating dc current is a type of dc current in which the magnitude of the current changes with time, but moves in one direction. For instance, the current produced in a junction diode rectifier.
Alternating current: Alternating current is the type of fluctuating current whose magnitude changes continuously and direction changes periodically.
In the given question, the current produced in a battery is flowing in one direction only.
Hence, the correct answer to the question will be direct current.
