If the mass of a sliding block is tripled while a constant net force is applied, by how much does the acceleration decrease?
Answers
As we know that if a rock is sliding under the influence of some external force then By Newton's II law we have
now we will have
now we know that if force remains constant while we tripled the mass of the block then
new acceleration of the block will be given as
so here the acceleration of the block will be decreased by 3 times

B) one Neutron
C) six Electrons
D) These masses are too tiny to measure
Answers
One proton or one neutron have very close to the same mass.
Their mass is about the same as the mass of 1,840 electrons !
So six electrons have roughly the same mass as 0.0033 of one
proton or one neutron.
Yes, these masses are very tiny. None of them was ever measured
until the 20th Century. But all of them have now been measured,
very precisely and accurately. This is very impressive, and should
give us a lot of admiration for scientists of the past hundred years.
It would be very interesting to look around online and find out
how they did it.

Unit Cell
Explanation:
- A unit cell is the smallest fundamental particle of a crystal structure that represents the structure of a crystal.
- Long-range, three-dimensional repetitiveness of this unit cell forms a crystal. A unit cell is composed of ions or atoms in a particular arrangement forming a well-defined structure.
- Crystal have a sharp melting and boiling point and when cut using a tool, they give a sharp edge on the pieces.

1 foot = 0.00018939 miles
300 foot = 0.056817 miles
Than seconds to hours:
2.92 seconds = 0.04867 minutes = 0.0008111 hours
Average speed :
v = d / t
v = 0.056817 miles / 0.008111 h
v = 70.05 miles per hour
b. A planet's orbit covers equal distances in equal amounts of time; the speed of a planet's orbit depends on its distance from the Sun; the bigger the planet, the slower it moves.
c. Planets orbit in elliptical patterns; a planet's orbit covers equal areas in equal amounts of time; planets' orbits are shorter or longer depending on their distance from the Sun.
Answers
The correct answer to the question is : C) Planets orbit in elliptical patterns; a planet's orbit covers equal areas in equal amounts of time; planets' orbits are shorter or longer depending on their distance from the Sun.
EXPLANATION:
Before coming into any conclusion, first we have to understand three laws of Kepler on planetary motion.
First law: Every planets moves around the sun in elliptical orbits with the sun situated at one of their foci.
Second law: Planets sweep out equal areas in equal interval of time.
Third law: The square of time period of rotation of every planet is directly proportional to the cube of semi major axis.
Hence, from above we see that the option three corresponds to the Kepler's laws partially.
Hence, the correct statement is option three.
Choices a). and b). each include some truth
mingled with some nonsense.
Choice c). is in fact a scientifically sloppy but intuitively
satisfying summary of Kepler's three laws of planetary motion.
