Explanation:
In general, hot wet climates accelerate chemical weathering while cold dry climates accelerate physical weathering. Although the rate of weathering depends on the type of rock, rocks in tropical climates experience the highest rates of weathering because of the combination of high heat and heavy rainfall.

A ball with a mass of .012 kg moving at 15.0 m/s collides with a second ball with a mass of 36 g
moving at 5.0 m/s. After the collision, the 12 g ball moves in the same direction at 6.0 m/s. What
is the resulting velocity of the 36 g ball?
Answer:
Final velocity of ball B V2 = 8 m/s
Explanation:
Given:
Mass of Ball A M1 = 12 gram
Mass of Ball B M2 = 36 gram
Initial velocity of ball A U1 = 15 m/s
Initial velocity of ball B U2 = 5 m/s
Final velocity of ball A V1 = 6 m/s
Find:
Final velocity of ball B V2
Computation:
Using conservation of momentum;
M1U1 + M2U2 = M1V1 + M2V2
(12)(15) + (36)(5) = (12)(6) + (36)(v2)
180 + 180 = 72 + (36)(v2)
Final velocity of ball B V2 = 8 m/s
You want to create a space station that is 50 meters in radius. If you want it to simulate Earth's gravitation, how fast must it go?
Answer:
w = 0.196 rad / s
Explanation:
To generate an acceleration similar to that of the earth, the station's centripetal acceleration must be equal to the acceleration due to gravity.
a_c = v² / r = w² r
a_c = g
we substitute
g = w² r
w² = g / r
w = [tex]\sqrt { \frac{g}{r} }[/tex]
let's calculate
w = √9.8/50
w = 0.196 rad / s
therefore the station must rotate at that angular velocity so that the acceleration in the outer wall is equal to the ratio of gravity

1. Why do you think it is important for people to know when the tides will be high and/or low?
Many reasons. Here are a couple:
1.) Water depth for the draft of incoming ships/vessels so they do not run aground.
2.) Distance between sea level and bottom of structures such as bridges for vessels passing underneath.

acontainer is filled whith mercury to alevel of 10m whit water to alevel of 8m and whit oil to alevel of 5m the densities oil ,water and mercury are 0.8g/cm³,1g/cm³ and 13.6g/cm³ calculate the total pressure exerted by the liquids at the base
Answer:
1450.4 KN[tex]m^{2}[/tex]
Explanation:
Pressure = ρhg
where: ρ is the density of the liquid, h is the height and g the force of gravity.
Total pressure exerted by the liquids at the base = Pressure of oil + Pressure of water + Pressure of mercury
So that,
i. Pressure of oil = ρhg
(ρ = 0.8 g/cm³ = 800 kg/m³)
= 800 x 5 x 9.8
= 39200
Pressure of oil = 39200 N[tex]m^{2}[/tex]
ii. Pressure of water = ρhg
(ρ = 1 g/cm³ = 1000 kg/m³)
= 1000 x 8 x 9.8
= 78400
Pressure of water = 78400 N[tex]m^{2}[/tex]
ii. Pressure of mercury = ρhg
(ρ = 13.6 g/cm³ = 13600 kg/m³)
= 13600 x 10 x 9.8
= 1332800
Pressure of mercury = 1332800 N[tex]m^{2}[/tex]
So that,
Total pressure exerted by the liquids at the base = 39200 + 78400 + 1332800
= 1450400
= 1450.4 KN[tex]m^{2}[/tex]
Total pressure exerted by the liquids at the base is 1450.4 KN[tex]m^{2}[/tex].
Calculate the momentum of a 1000 kg sports car traveling at 30 m/s.
Answer:
30,000 kgm/s
Explanation:
m = 1000 kg
v = 30 m/s
Plug those values into the equation:
p = mv
p = (1000 kg)(30 m/s)
p = 30,000 kgm/s
The momentum of a 1000 kg sports car traveling at 30 m/s is 30,000 kgm/s.Linear momentum = Mass x Speed.
What is the momentum?The product of an object's mass, m, and its velocity, v, is the vector quantity known as linear momentum. It is represented by the letter "p," which is also used to denote momentum.
Mass of car = 1000 kg
Speed by which car moves = 30 m/s. The momentum of the car =?
Recall that:
Linear momentum = Mass x Speed
= 1000 kg x 30 m/s.
= 30,000 kgm/s
The sum of an object's mass (m) and velocity (v) is known as the object's linear momentum. An equation can be used to explain this relationship. Momentum is defined as the body's mass times its velocity. P = m times v, etc.
Therefore, the momentum of a 1000 kg sports car is 30,000 kgm/s if travels at 30 m/s.

what is the correct equation for calculating kinetic energy?
1. kinetic energy = potential energy - total energy
2. kinetic energy = total energy - potential energy
3. kinetic energy = 1/2 x (total energy + potential energy)
4. kinetic energy = potential + total energy
Answer:
2. kinetic energy = total energy - potential energy
Explanation:
The total energy of a system is the addition of kinetic and potential energy of the system. Kinetic energy can be regarded as form of energy posses by an object when it's in motion
Total energy = kinetic energy + potential energy
(If we make Kinectic energy the subject of the formula, we have)
kinetic energy = total energy - potential energy

An object is most likely to become electrically charged by gaining or losing which type of particles?
neutral particles
positive particles
negative particles
none of the above
Answer:
negative particles
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.
Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others. Thus, this property is typically used to determine the chemical properties of elements.
Hence, an object is most likely to become electrically charged by gaining or losing negative particles.
Define A Gamma Ray .....---_---__☘️
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.
