A velocity vs. time graph is shown. A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 5, velocity in meters per second on the y axis, numbered 0 to 20. A line starts at the origin and ends at (5, 20). What is the acceleration of the object? 0 m/s2 0.25 m/s2 4 m/s2 8 m/s2
Answer:
C
Explanation:
Given that a line starts at the origin ( 0, 0) and ends at (5, 20)
Where
V1 = 0
V2 = 20
T1 =0
T2 = 5
The slope or gradient of a velocity time graph is the acceleration.
Slope = change in V/ change in t
That is,
Slope = ( V2 - V1 )/ ( T2 - T1 )
Substitutes all the values into the formula
Slope = ( 20 - 0 )/( 5 - 0 )
Slope = 20/5
Slope = 4 m/s^2
Therefore, acceleration of the object is 4m/s^2

Answer:
The found value of r is:
r = 94.7
Explanation:
We know that
cosθ = Base / Hypotenuse
θ is the always the angle between base and hypotenuse
In this right angles triangle, the angle θ is given 63°.
Which means that the Base is 43 and the hypotenuse is r
Base = 43
Hypotenuse = r
Substitute θ=63°, Base = 43 and hypotenuse = r in the formula of cosθ mentioned above:
cos 63° = 43/r
Rearrange
r = 43/cos63°
r = 43/0.454
r= 94.7

In an area of the deep ocean, hot magma emerges from a crack in Earth’s crust. Which statement describes what will happen to the seawater above the crack as a result of convection?
Water molecules will break apart and flow in a circular pattern.
Water molecules will bond together and rise upward.
The water will become more dense and sink downward.
The water will become less dense and rise upward.
Answer: D
Explanation:
Hot magma erupts from a crack in Earth’s crust with a very high temperature that will surely break the bond of water molecules in contact. As a result of this, The water molecules will become less dense and rise upward.
Therefore, "The water will become less dense and rise upward " is the best statement to describes what will happen to the seawater above the crack as a result of convection.
The water will become less dense and rise upward because less denser materials move upward and more denser comes downward.
What will happen to the seawater above the crack as a result of convection?The seawater will become less dense and rise upward above the crack as a result of convection because water is less denser and the magma that erupts from the crack is denser due to its high viscosity.
So we can conclude that the water will become less dense and rise upward because less denser materials move upward and more denser comes downward.

Answer:
B. 1500 kg*m/s
Explanation:
Momentum p = m* v
In any type of collision, the total momentum is preserved!
The total momentum before and the total momentum after the collision is the same. We know the mass and speed after the collision so we can calculate the total momentum.
p1 + p2 =
m1*v1 + m2*v2
m1 = me = 300 kg
v1 = 3 m/s
v2 = 2 m/s
Substitute the given numbers:
300*3 + 300+2
900 + 600
1500 kg*m/s, which is answer B.

As hotter material _______, ________material sinks. a. Sinks, colder b. Rises, warmer c. Rises, colder d. Sinks, warmer
Answer:
C
Explanation:
Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water.
As hotter material gets colder it will sinks down. In the hotter state the molecules gets energetic and gets far apart making them free to rise in the air. Thus option a is correct.
What is sinking ?Hot air is less dense than cold air, which is why hot air rises and cold air descends. The earth's weather is controlled by hot and cold air currents. The planet is heated primarily by the sun, which also generates the planet's hot and cold air energy systems.
Since warm air currents originate over oceans, they frequently bring rain. Tropical storms and hurricanes develop at sea and eventually travel near land for this reason.
As hot air from the earth's surface rises, it rapidly turns into cold air as it approaches space. As hot air cools, it descends back to the earth's surface, where it is warmed by the ocean before rising once more. An example of this is a convection current. Thus, option a is correct.

We need to find how the gravitational force between two object decreases.
The gravitational force between the objects will decrease by
increasing the distance between the objects
decreasing the mass of one of the objects
decreasing the mass of both objects
Gravitational force is given by
[tex]F=\dfrac{Gm_1m_2}{r^2}[/tex]
where
[tex]G[/tex] = Gravitational constant = [tex]6.674\times 10^{-11}\ \text{Nm}^2/\text{kg}^{2}[/tex]
[tex]m_1[/tex] = Mass of one object
[tex]m_2[/tex] = Mass of other object
[tex]r[/tex] = Distance between the two objects
It can be seen that the gravitational force is proportional to the mass of the objects
[tex]F\propto m_1m_2[/tex]
and inversely proportional to the square of the distance between them
[tex]F\propto \dfrac{1}{r^2}[/tex]
So, if mass of one of the objects decreases then the gravitational force will decrease.

ASAP please! Three positive charges are arranged as shown in the diagram. Three charges at the corners of an isosceles triangle. The two charges at the base are +5 microcoulombs and +9 microcoulombs and are separated by .32 m. The triangle is .42 m tall up to a charge +3 microcoulombs. The other two sides of the triagle are both .45 m. What is the magnitude and direction of the net electrical force acting on the +3 µC charge? magnitude: 1.75 N direction: 6.2° north of east magnitude: 1.75 N direction: 6.2° south of east magnitude: 1.86 N direction: 21° north of east magnitude: 1.86 N direction: 21° south of east
Answer:
Fn = 1,78 [N]
β = 6,4⁰ north-east direction
Explanation:
As all charges are positive, forces between electric charges located in the cornes of the base of the triangle and the charge located in the top of the isoceles triangle, are repulsion forces. The east-west direction will depend on where the biggest charge is located, if Q₁ = 9 microC, is in the left end of the triangle base then force on charge Q₃ = 3 microC will have direction north-east, if the above mention configuration change (that means Q₁ is in the right end of the triangle base) then the force will have north-west direction. As in the answer solution, 1,75 [N] direction north-east is offer, we will choose the first configuration. According to that:
K = 1/4*π*ε₀ K = 8,98*10⁹ [N*m²/C²]
The angles in the base of the triangle are equals (we call it α )
sinα = 0,42/045 = 0,93
α = 69⁰
cosα = 0,356
And Q₃ = 3 mC = 3*10⁻⁶ C
Q₁ = 9 mC = 9*10⁻⁶ C
Q₂ = 5 mC = 5*10⁻⁶ C
F₁ [Q₁,Q₃] = K*Q₁*Q₃/d² ⇒F [Q₁,Q₃] = 8,98*10⁻⁹ * 9*10⁻⁶ * 3*10⁻⁶/(0,45)²[N]
F₁ [Q₁,Q₃] = 1,2 [N] direction along the side of the triangle therefore
its components are:
F₁ₓ = F₁* cosα ⇒ F₁ₓ = 1,2 * 0,356
F₁ₓ = 0,43 [N]
F₁y = F₁ *sinα ⇒ F₁y = 1,2 * 0,93
F₁y = 1,16 [N]
Now
F₂ [Q₂,Q₃] = K*Q₂*Q₃/d² ⇒F [Q₂,Q₃] = 8,98*10⁻⁹ * 5*10⁻⁶ * 3*10⁻⁶/(0,45)²[N]
F₂ = 0,67 [N]
F₂ₓ = F₂* cosα ⇒ F₂ₓ = 0,67*0,356
F₂ₓ = 0,24 [N]
F₂y = F₂*sinα ⇒ F₂y = 0,67*0,93
F₂y = 0,62 [N]
We must remember F₁ and F₂ are repulsion forces, then components over y-axis have the same sense (we must add then) and components over x-axis have to be subtracted, in this case, the sense is determine by major force component (to the right) according to this:
Fy = F₁y * F₂y = 1,16 + 0,62
Fy = 1,78 [N]
And
Fₓ = F₁ₓ - F₂ₓ = 0,43 - 0,24
Fₓ = 0,19
Net force module is:
Fn = √ (1,78)² + (0,19)²
Fn = 1,79 [N]
Having an angle respect the y-axis:
tan β = 0,19/1,78 ⇒ tan β = 0,11 and from tan tables
β = 6,4⁰ north-west direction
Answer: magnitude: 1.75 N ; direction: 6.2° north of east

A 4.0 kg block is resting on a rough horizontal table. The coefficient of static friction us is 0.60. The static friction between the block and the table before any attempted motion is to start is N. (round to the nearest integer)
Answer: 24 N
Explanation:
Given that the
Mass m = 4 kg
Coefficient of friction (μ) = 0.60
To calculate the static friction between the block and the table before any attempted motion, you will use the formula; F = (μ)N
Where
F = static friction
N = normal reaction = mg
g = acceleration due to gravity = 9.8 m/^2
Substitutes m, g and (μ) into the formula
F = 0.6 × 4 × 9.8
F = 23.52 N
Therefore, the static friction between the block and the table before any attempted motion is 24 N approximately.
The static friction between the block and the table before any attempted motion is to start equals 23.52 Newton.
Given the following data:
Mass of block = 4.0 kgCoefficient of static friction = 0.60.To determine the static friction between the block and the table before any attempted motion is to start:
Mathematically, the force of static friction is given by the formula;
[tex]F_s = uF_n[/tex] ...equation 1.
Where;
[tex]F_s[/tex] represents the force of static friction.μ represents the coefficient of friction.[tex]F_n[/tex] represents the normal force.But, [tex]F_n = mg[/tex]
[tex]F_s = umg[/tex] ...equation 2.
Substituting the given parameters into eqn. 2, we have;
[tex]F_s = 0.60 \times 4 \times 9.8\\\\F_s = 23.52\; Newton[/tex]
Force of static friction = 23.52 Newton

Answer:
The three components of effective communication are:
Sending CommunicationReceiving CommunicationFeedbackExplanation:
1) Sending CommunicationOne should think about what he is going to say, structure his message and focus clearly on a the purpose of sending a message. For example if an employer wants to communicate an employee to improve his performance, he should focus hid communication on the results rather than on his failures.
2) Receiving CommunicationThe person on the other end of the communication should be a good listener. For example in the example given, even if the employer effectively communicates his side of the communication, but the employee is not paying his full attention to what his boss is saying, he wouldn't be able to make much of a difference.
3) FeedbackAfter sending and receiving communication, feedback should be given to complete the communication effectively. For example the employer may tell his boss about what he understood from his boss's speech, or what will he do to improve his performance.
