Answer: static friction
Explanation:
During sliding, contact points do not get enough time to get interlocked properly. Therefore, less friction. But, when the object is at rest, the surfaces interlock well, therefore friction is more. This explains why sliding friction is less than static friction.

2. Keith took a cube and measured the mass and volume of a
cube. He discovered the mass to be 36g and the volume to be
6 cm3. What is the density of the cube?
Answer:
6 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 36 g
volume = 6 cm³
We have
[tex]density = \frac{36}{6} = 6 \\ [/tex]
We have the final answer as
6 g/cm³Hope this helps you

A ball is thrown horizontally with an initial velocity of 5.0 meters per second.
The ball travels 15 meters horizontally before it lands. What vertical height
was it thrown from?
Hi there!
We can begin by calculating the total time of the ball's projectory:
t = d/v
t = 15/5 = 3 sec
We can use the simplified kinematic equation for time:
t = √2h/g
Rearrange to solve for h:
t² = 2h/g
gt² = 2h
gt²/2 = h
Plug in the values: (g = 9.8 m/s²)
9.8(3)² / 2 = 44.1 m

If a car's velocity increases to 30 m/s from rest in 6.0 seconds, what is the acceleration?
Hi there!
We can use the following equation to derive acceleration:
vf = vi + at, where:
vi = 0 m/s (starts from rest)
a = acceleration
time = time (sec)
Rewrite:
vf = at
Solve for acceleration:
vf/t = a
30/6 = 5 m/s²

b
Magnets do not have to touch each other to experience a force.
c
Magnets push each other apart to increase the distance between them.
d
Magnets must be large in size in order to exert a force that is strong enough to notice.

Identifying What are five things
that must be true in order for
a substance to be considered a
mineral?
Answer:
1. Naturally occuring
2. Solid
3. Inorganic
4. Crystalline
5. Specific Chemical Compostion
Explanation:
Minerals are inorganic, crystalline solids that occur during biogeochemical processes in nature like in cooled lava or evaporated sea water. Minerals are not rocks, but are actually the components that make up rocks. Though they vary in color and shape, each mineral has a distinct chemical composition.
1. Minerals are formed by natural geological processes. Most minerals form from molten lava, sea evaporation or hot liquids in caves or cracks. Laboratory-generated minerals like synthetic gems made for commercial purposes are not considered actual minerals.
2. Though minerals vary in shape, color, luster (the way a mineral reflects light) and hardness, all minerals are a solid at a given temperature. If a substance is not in its solid state, it is not currently a mineral. For example, ice is a mineral, but liquid water is not. The Mohr scale, rates a minerals hardness from one to 10, 10 being the hardest. Diamond is the hardest mineral. Talc is a very soft mineral with a Mohr rating of one.
3. Minerals are wholly inanimate, inorganic compounds. But there are exceptions to this qualifier. There are rare organic substances with definitive chemical compositions that are labeled as “organic minerals." The most famous of this oxymoronic exception is whewellite. Whewellite is a component of kidney stones and coal deposits.
4. Most minerals will grow into a crystal shape, space permitting. Mineral deposits are often small because there is usually a variety of minerals in the same vicinity competing for the same room to grow. A mineral’s crystalline structure determines its hardness, cleavage (how it breaks) and color. There are six different crystal shapes: cubic, tetragonal, orthohombic, hexagonal, monoclinic and triclinic.
5. A mineral is defined by its chemical composition. A rock, on the other hand, does not have a specific chemical composition because it is a composite of a variety of minerals. Minerals are classified based on their anionic group. The major mineral groups are native elements, sulfides, sulfosalts, oxides and hydroxides, halides, carbonates, nitrates, borates, sulfates, phosphates and silicates. Silica is abundant in the Earth’s crust, so silicates are the most common group of mineral.

the energy for building a proton gradient is provided by
Answer:
The electrons from from NADH and FADH2 flow through the electron transport chain in the inner mitochondrial membrane generating a H+ buildup in the inner membrane space. This proton gradient (gradient of H+) flowing through the membrane enzyme complex ATP synthetase is the direct energy source for producing ATP.

3. A rescue plane drops a package to a stranded party of explorers. The plane is traveling horizontally at a velocity of
100.0 m/s at a height of 50.0 m above the ground.
a. How long will it take for the package to hit the ground?
Hi there!
For this part, we can disregard the horizontal velocity because horizontal and vertical motion are INDEPENDENT.
We can used the simplified equation to solve for time:
[tex]t = \sqrt{\frac{2h}{g}}[/tex]
Where:
h = height
g = acceleration due to gravity (assume g = 10 m/s²)
Plug in given values:
[tex]t = \sqrt{\frac{2(50)}{10}} = \sqrt{10}[/tex]
t ≈3.162 sec
