Total distance between Sally's house and mall = 10 kilometers
Distance covered during half way drive = Kilometers
Now, she goes back to her home.
Distance covered going back home = Kilometers
Now, she drives from home to mall.
Distance covered from Sally's home to mall = 10 kilometers
Hence, the total distance Sally traveled = 5 + 5 + 10
Total distance Sally traveled = 20 kilometers
Hence, the answer is 20 kilometers
Answer:
Grid
Explanation:
The number of electrons attaining the fluorescent light is regulated by the grid in a cathode ray tube.When the heater is supplied with current, it allows the electrons to emit from the cathode. Before approaching the anode the electrons pass through grid opening. The number of electrons attempting to reach the anode may also be regulated by managing the number of electrons passing through the grid.
Answer:
The kinetic energy when the film vault landed is 12744000J.
Explanation:
The kinetic energy is defined as:
(1)
Where m is the mass and v is the velocity.
By means of equation 1, the kinetic energy of the film vault when it landed can be determined
But
Hence, the kinetic energy when the film vault landed is 12744000J.
Answer: Asteroids, meteoroids, and comets are remnants of the early solar system. This Statement is TRUE.
Explanation:
METEOROID: these are small rocky or metallic objects found in outer space.
ASTEROIDS: these are also known as minor planets of the inner solar system. They are irregularly shaped object in space that orbits the Sun.
COMETS: these are dusty chunk of ice, that moves in a highly elliptical orbit about the sun.
Asteroids, meteoroids, and comets as remnants of the early solar system was further proved in nebular hypothesis
initially proposed in the eighteenth century by German philosopher Immanuel Kant and French mathematician Pierre-Simon Laplace. (The word nebula means a gaseous cloud.) According to the modern version of the theory, about 4.5 to 5 billion years ago the solar system developed out of a huge cloud of gases and dust floating through space. These materials were at first very thin and highly dispersed.
