This diagram shows two different forces acting on a skateboarder. The combined mass of the skateboard and the person is 81.5 kg. Based on this information, what is the acceleration of the skateboarder?
A. 0.51 m/s² to the left
B. 1.95 m/s² to the left
C. 0.51 m/s² to the right
D 1.94 m/s² to the right
Answers
Answer:
Option C. 0.51 m/s² to the right.
Explanation:
We'll begin by calculating the net force acting on the skateboarder. This is illustrated below:
Force applied (Fₐ) = 52.8 N
Force resistance (Fᵣ) = 11.4 N
Net force (Fₙ) =.?
Net force (Fₙ) = Force applied (Fₐ) – Force resistance (Fᵣ)
Fₙ = Fₐ – Fᵣ
Fₙ = 52.8 – 11.4
Fₙ = 41.4 N to the right
Thus, the net force acting on the skateboarder is 41.4 N to the right.
Finally, we shall determine the acceleration of the skateboarder as shown below:
Mass (m) = 81.5 kg.
Net force (Fₙ) = 41.4 N to the right
Acceleration (a) =..?
Net force (Fₙ) = mass (m) × acceleration (a)
Fₙ = ma
41.4 = 81.5 × a
Divide both side by 81.5
a = 41.4 / 81.5
a = 0.51 m/s² to the right.
Therefore, the acceleration of the skateboarder is 0.51 m/s² to the right.
Answer: .5 m/s to right

Answers
Answer:
15.71 m/s
Explanation:
We are given;
Time; t = 0.2 s
Radius; r = 0.5 m
The circumference will give us the distance covered.
Formula for circumference is 2πr
Thus; Distance = 2πr = 2 × π × 0.5 = π
Linear speed = distance/time = π/0.2 = 15.71 m/s

Two hockey players are about to collide on the ice, One player has a mass of
65 kg and is traveling at 1.8 m/s east. The other has a mass of 70 kg and is
traveling at 1.4 m/s west. The system consists of the two hockey players,
According to the law of conservation of momentum, what is the total
momentum of the system after they collide? Assume the collision is an
elastic collision
A. 19 kg'm/s east
B. 215 kgm/s east
C. 19 kgm/s west
D. 215 kgm/s west
Answers
Answer: 19kg•m/s east
Explanation:
The total momentum of the system after they collide will be equal to 19 kg m/s east. Hence, option A is correct.
What is momentum?The momentum is the result of a particle's velocity and its mass. Force and motion, meaning it has both magnitude and the direction. According to Isaac Newton's second equation of motion, the force acting on a particle equals the time rate of increase of momentum.
The impulse, which is the product of the force and the intervals (the impulse), is equal to the difference in momentum, according to Newton's 2nd law, if a steady force operates on a particle for a specific amount of time. On the other hand, a particle's momentum is the amount of time needed for a consistent action to fight it to rest.
As per the given information in the question,
Mass, m₁ = 65 kg
Mass, m₂ = 70 kg
Velocity, v₁ = 1.8 m/s
Velocity, v₂ = 1.4 m/s
Use the law of conservation of momentum,
P = m₁v₁ = m₂v₂
Here, P is the total momentum.
⇒ 65 × 1.8 = 78 × 1.4
= 117 east = 98 west
P = 117 - 98
P = 19 kg m/s east.

Suppose you are climbing a hill whose shape is given by the equation z = 2000 − 0.005x2 − 0.01y2, where x, y, and z are measured in meters, and you are standing at a point with coordinates (60, 40, 1966). The positive x-axis points east and the positive y-axis points north. (a) If you walk due south, will you start to ascend or descend? ascend descend Correct: Your answer is correct. At what rate? Correct: Your answer is correct. vertical meters per horizontal meter (b) If you walk northwest, will you start to ascend or descend? ascend descend Correct: Your answer is correct. At what rate? (Round your answer to two decimal places.) Correct: Your answer is correct. vertical meters per horizontal meter (c) In which direction is the slope largest? What is the rate of ascent in that direction? vertical meters per horizontal meter At what angle above the horizontal does the path in that direction begin? (Round your answer to two decimal places.)
Answers
Answer:
(a) Ascend at 0.8 vertical meter/meter
(b) Descend at -0.2·√2 vertical meter/meter
(c) In the (-0.6, -0.8) direction. The path begins at 45° to the horizontal
Explanation:
The given equation of the shape of the hill is z = 2000 - 0.005·x² - 0.01·y²
The current location = (60, 40, 1966)
The direction of the positive x-axis = east
The direction of the positive y-axis = north
(a) Walking due south = Reducing the y-value 40
From the equation, the elevation varies inversely with the motion towards the north
Therefore, walking south increases the elevation, and we ascend
The rate is given by the partial derivative at in the -j direction, which is 0.02
The rate is therefore 40 × 0.02 = 0.8
(b)The unit vector in the northwest direction u = 1/√2·(-1, 1)
∴ The rate = (-0.01(60), -0.02(40))·u = (-0.6, -0.8)·1/√2·(-1, 1) = -0.2·√2
Therefore we descend
(c) The slope is largest in the grad of the function at the point (60, 40) which is given as follows;
d(2000 - 0.005·x² - 0.01·y² )/dx, d(2000 - 0.005·x² - 0.01·y² )/dy = (-0.6, -0.8)
Therefore, the direction is tan⁻¹(-0.8/-0.6) ≈ S 36.87° W
The slope =(√((-0.4)² + (-0.8)²) = 1
Therefore, the angle is 45° to the horizontal.
a phosphorus atom needs to gain ---electrons to achieve a full octet
Answers
Answer:
Three (3).
Explanation:
The octet rule is a rule in chemistry that states that, chemical elements would either gain or loss electrons in their outermost shell in order to attain a stable electronic configuration i.e having eight (8) valence electrons in their outermost shell such as chemical elements found in group 8 (2-8-8) known as noble gas.
A phosphorus atom needs to gain three (3) electrons to achieve a full octet because the atomic number of phosphorus is 15 and as such it has the electronic configuration of 2-8-5 and needs three electron in order to become a stable element.

b. The decomposition of radioactive elements causes heat in the interior part of

c. Heat slowly rises to the mantle and creates convection current.
d. Heat moves to the core.
e. The process repeats as cycle.
Answers
Answer:
1) Lithospheric plates move in the asthenosphere due to rising and sinking of materials is 1.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core
5) The process repeats as cycle.
Explanation:
Mantle convection is the gradual slow creeping of movement of the Earth's mantle which is as a result of convection current which transfer heat from the interior to the surface of the Earth .
The process of mantle convection start with
1. Lithospheric plates move in the asthenosphere due to rising and sinking of materials is and thus form the two component of the mantle.
2) The decomposition of radioactive elements causes heat in the interior part of the Earth. This is as a result of accretion which is associated to sea flooding
3) Heat slowly rises to the mantle and creates convection current.
4). Heat moves to the core, cools down by conduction and convection of heat.
5) The process repeats as cycle.
The proper and correct arrangement of events in the mantle convection process are:
1. The decomposition of radioactive elements causes heat in the interior part of the Earth.
2. Heat moves to the core
3. Heat slowly rises to the mantle and creates convection current.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process repeats as a cycle.
Convection is considered to be one of the most efficient ways through which heat is transported from the interior of planet Earth to the surface.
Mantle convection can be defined as the very slow transfer of heat due to the movement of Earth's solid silicate material within the mantle.
Basically, the slow creeping of the mantle causes a transfer of heat from the white-hot core to the brittle lithosphere during mantle convection.
Furthermore, the heating of the mantle takes place from below (the core) and it rises upward in hotter regions while it sinks down in colder regions.
The proper and correct arrangement of events in the mantle convection process are:
1. Heat is caused in the interior part of the Earth due to the decomposition or decay of radioactive elements.
2. Heat moves to the core.
3. Heat slowly rises from the Earth's core to the mantle and creates convection current in the asthenosphere, which is the plastic layer of the mantle.
4. Lithospheric plates move in the asthenosphere due to rising and sinking of materials.
5. The process is then repeated as a cycle.
