Where would you find convergent and divergent plate boundaries relative to
convection currents in the mantle?
Answer:
When two tectonic plates meet, we get a “plate boundary.” There are three major types of plate boundaries, each associated with the formation of a variety of geologic features.
Explanation:
When the plates meet at the boundaries the convergent boundaries lie at the collision of two plates and the divergent lies near mid-oceanic ridges.
What are plate boundaries?The earth plate tectonics are divided into the three types of plates as convergent which is the destruction of crust and are found where the heavy and light plate comes and colloid with each other submerging the heavier plate into the mantel.
The divergent ones found near the mid-oceanic ridges are the formation of a new plate as the plates diverge away from the ridges.

A mover slides a refrigerator weighing 650 N at a constant velocity across the floor
a distance of 8.1 m. The force of friction between the refrigerator and the floor is
230 N. How much work has been performed by the mover on the refrigerator?
Answer: The work is 1863 N*m
Explanation:
We can define work as:
W = F*d
Where F is the force that the mover needs to apply to the refrigerator, and d is the distance that the refrigerator is moved.
To move the refrigerator, the minimal force that the mover needs to do is exactly the friction force (In this case, the refrigerator will move with constant speed).
Then we will have:
F = 230 N
and the distance is 8.1 meters, then the work will be:
W = 230N*8.1 m = 1863 N*m

What is the amount of space that a gas takes up called?
ASAP 20 points???
Answer:
Mass is the amount of matter an object has, and volume is the amount of space the matter takes up. Solids are easy to recognize. They have definite shape, mass, and volume. Trees are solids.
Explanation:
The amount of space occupied by a gas is called volume of the gas. The volume of a gas depends on the temperature and pressure.
What is volume ?Volume is a physical parameter describing the space occupied by a substance. Volume is an extensive property. Therefore, volume is dependent upon amount of the substance.
The total amount of a substance is called its mass. Density describes how closely its particles are packed in a given volume. Hence, volume is the ratio of mass to the density.
Volume of a gas changes with its temperature and pressure. As the pressure increases, volume increases whereas, as the temperature increase, volume increases.

a spy satellite of mass of 1000 kg is orbiting the earth at an altitude of 300 km/s
a) what is its period
b) what is its orbital speed
Answer:
a) The period of the satellite is approximately 5,425.305 seconds (1.507 hours)
b) The orbital velocity of the satellite is approximately 7,725.8565 m/s
Explanation:
The given parameters are;
The mass of the satellite, m = 1,000 kg
The altitude at which the satellite is orbiting, h = 300 km
a) The period of the satellite is given as follows;
[tex]T = 2 \times \pi \times \sqrt{\dfrac{(R + h)^3}{g \times R^2} }[/tex]
Where;
R = The radius of the Earth = 6.371 × 10⁶ m
g = The acceleration due to gravity = 9.81 m/s²
h = The altitude of the orbit of the satellite = 300 km = 300,000 m
By substitution, we have;
[tex]T = 2 \times \pi \times \sqrt{\dfrac{((6.371 + 0.3)\times 10^6)^3}{9.81 \times (6.371 \times 10^6)^2} } \approx 5,425.305[/tex]
T ≈ 5,425.305 seconds ≈ 1.507 hours
b) The orbital velocity of the satellite is given as follows;
[tex]v_0 = \sqrt{\dfrac{G \times M_{central}}{R + h} } = \sqrt{\dfrac{g \times R^2}{R + h} }[/tex]
Where;
v₀ = The orbital velocity of the satellite
Which by substitution gives;
[tex]v_0 = \sqrt{\dfrac{9.81 \times (6.371 \times 10^6)^2}{(6.371 + 0.3) \times 10^6} } = 7,725.8565[/tex]
The orbital velocity, v₀ = 7,725.8565 m/s.

Melinda is taking a tour through a new city on the tour she walk there .40 miles south 0.65 miles east 0.78 miles north 1.24 miles west then 1.20 miles south at the end of the tour what is Melinda's displacement vector
Answer:
The displacement vector is [tex]-0.59 \hat i -0.82 \hat j[/tex]
Explanation:
Taking East as positive x-axis having a unit vector [tex]\hat i[/tex] and North as positive y-axis having a unit vector [tex]\hat j[/tex].
So, west and south are in negative x and negative y directions respectively.
As she walks 0.40 miles south, 0.65 miles east, 0.78 miles north, 1.24 miles west then 1.20 miles south.
Scaling 1 mile as 1 unit vector, so 1 mile east = 1 [tex]\hat i[/tex] and so on
Adding all the displacement vectors, we have
[tex]\vec {v} = -0.40 \hat j +0.65 \hat i + 0.78 \hat j -1.24 \hat i - 1.20 \hat j[/tex]
[tex]\vec {v} = -0.59 \hat i -0.82 \hat j[/tex]
Hence, the displacement vector is [tex]-0.59 \hat i -0.82 \hat j[/tex]

A sealed can of your favorite soda has a carbon dioxide gas (CO2) volume of 0.05 L. When it is refrigerated, the pressure is 207 kPa. When you open it, the pressure drops to 101 kPa. After opening, what will the new volume of the carbon dioxide gas be?
Answer:
0.1 L
Explanation:
From the question given above, we obtained the following data:
Initial volume (V₁) = 0.05 L
Initial Pressure (P₁) = 207 KPa
Final pressure (P₂) = 101 KPa
Final volume (V₂) =?
We can obtain the new volume (i.e the final volume) of the gas by using the Boyle's law equation as illustrated below:
P₁V₁ = P₂V₂
207 × 0.05 = 101 × V₂
10.35 = 101 × V₂
Divide both side by 101
V₂ = 10.35 / 101
V₂ = 0.1 L
Thus, the new volume of the gas is 0.1 L

A football player at practice pushes a 80 kg blocking sled across the field at a constant speed. The coefficient of kinetic friction between the grass and the sled is 0.30. How much force must he apply to the sled
Answer:
The value is [tex]F = 235.2 \ N[/tex]
Explanation:
From the question we are told that
The mass of the sled is [tex]m = 80 \ kg[/tex]
The coefficient of friction is [tex]\mu = 0.30[/tex]
Generally the force that must be applied to the sled is equal to the frictional force experienced by the sled which is mathematically represented as
[tex]F = m * \mu * g[/tex]
=> [tex]F = 80 * 0.30 * 9.8[/tex]
=> [tex]F = 235.2 \ N[/tex]
Consider a 12.5 kg baby tiger in a tree has 490 J of gravitational potential energy. Determine the height of the tiger above the ground?
Answer:
[tex]\boxed {\boxed {\sf 4 \ meters}}[/tex]
Explanation:
Gravitational potential energy can be found using the following formula:
[tex]E_P=m*g*h[/tex]
where m is the mass, g is the gravitational acceleration, and h is the height.
The mass of the tiger is 12.5 kilograms. The gravitational acceleration on Earth is 9.8 m/s².
The potential energy is 490 Joules. Convert the units to simplify cancelling units later. 1 Joule is equal to 1 kilogram * meter² /second²Our answer of 490 J = 490 kg*m²/s²[tex]m= 12.5 \ kg \\g= 9.8 \ m/s^2\\E_p= 490 \ kg*m^2/s^2[/tex]
Substitute the values into the formula.
[tex]490 \ kg*m^2/s^2 = 12.5 \ kg * 9.8 \ m/s^2 *h[/tex]
Multiply 12.5 kg and 9.8 m/s²
12.5 kg* 9.8 m/s² = 122.5 kg*m/s²[tex]490 \ kg*m^2/s^2 = 122.5 \ kg *m/s^2 *h[/tex]
Since we are trying to solve for h, we must isolate it. Since h is being multiplied by 122.5, we must divide both sides by that number because the inverse of division is the inverse of multiplication.
[tex]\frac{490 \ kg*m^2/s^2} { 122.5 \ kg *m/s^2}= \frac{ 122.5 \ kg *m/s^2 *h }{ 122.5 \ kg *m/s^2}[/tex]
Note that when dividing, the kg*m/s² will cancel each other out, but a m (meter) will be left.
[tex]\frac{490 \ m }{122.5} =h[/tex]
[tex]4 \ m =h[/tex]
The tiger was 4 meters above the ground.

Two balloons are charged with an identical quantity and type of charge: -0.0025 C. They are held apart at a separation distance of 8 m. Determine the magnitude of the electrical force of repulsion between them.
Answer:
F = 878.9 N
Explanation:
The electrostatic force of attraction or repulsion is given by Coulomb's Law as follows:
F = kq₁q₂/r²
where,
F = Force pf repulsion between balloons = ?
k = Coulomb's Constant = 9 x 10⁹ N.m²/C²
q₁ = q₂ = magnitudes of 1st and 2nd charge = 0.0025 C
r = distance between balloons = 8 m
Therefore,
F = (9 x 10⁹ N.m²/C²)(0.0025 C)(0.0025 C)/(8 m)²
F = 878.9 N
The magnitude of the electrical force of repulsion between them is F = 878.9 N
Calculation of the magnitude of the electrical force:
Here we use Coulomb's Law
F = kq₁q₂/r²
Here,
F = Force of repulsion
k = Coulomb's Constant = 9 x 10⁹ N.m²/C²
q₁ = q₂ = magnitudes of 1st and 2nd charge = 0.0025 C
r = distance between balloons = 8 m
So,
F = (9 x 10⁹ N.m²/C²)(0.0025 C)(0.0025 C)/(8 m)²
F = 878.9 N
Hence, The magnitude of the electrical force of repulsion between them is F = 878.9 N

Describe how different types of motion are represented by distance-time graphs and velocity-time graphs.
Answer:
non-accelerated movement
velocity versus time a horizontal straight line.
distance versus time gives a horizontal straight line.
accelerated motion
graph of velocity versus time s an inclined line and the slope
graph of distance versus time is a parabola of the form
Explanation:
In kinematics there are two types of steely and non-accelerated movements
In a the velocity of the body is constant therefore a speed hook against time gives a horizontal straight line.
A graph of distance versus time is a straight line whose slope is the velocity of the body
x = v t
In an accelerated motion the velocity changes linearly with time, so a graph of velocity versus time is an inclined line and the slope is the value of the acceleration of the body
v = v₀ + a t
A graph of distance versus time is a parabola of the form
x =v₀ t + ½ a t²
