How much force does a 35 kg child have that is running through the house at an acceleration of 20 m/s^2?
Answer:
The answer is 700 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × accelerationFrom the question
mass = 35 kg
acceleration = 20 m/s²
We have
force = 35 × 20
We have the final answer as
700 NHope this helps you

An object accelerates from rest to a velocity of 34 m/s
over a distance of 70 m. What was its acceleration?
Answer:
6.8m/s²
Explanation:
Given parameters:
Initial velocity = 0m/s
Final velocity = 34m/s
Distance = 70m
Unknown:
To solve this problem we apply one of the motion equations;
V² = U² + 2aS
where V is the final velocity
U is the initial velocity
a is the acceleration
S is the distance covered
Input the parameters and solve;
34² = 0² + 2 x a x 70
34² = 140a
a = 6.8m/s²
To understand the origin of the torque on a current loop due to the magnetic forces on the current-carrying wires.
This problem will show you how to calculate the torque on a magnetic dipole in a uniform magnetic field. We start with a rectangular current loop, the shape of which allows us to calculate the Lorentz forces explicitly. Then we generalize our result. Even if you already know the general formula to solve this problem, you might find it instructive to discover where it comes from.
a) Give a more general expression for the magnitude of the torque τ. Rewrite the answer found in Part A in terms of the magnitude of the magnetic dipole moment of the current loop m. Define the angle between the vector perpendicular to the plane of the coil and the magnetic field to be ϕ, noting that this angle is the complement of angle θ in Part A.
Give your answer in terms of the magnetic moment m, magnetic field B, and ϕ.
Answer:
The torque is [tex]\tau = B * m sin(\phi )[/tex]
Explanation:
Generally when current flow through a rectangular loop the magnetic dipole generated we can denote this as [tex]\vec m[/tex]
Here k is the length of the side of one side of the rectangular loop
Now when this loop is place in a magnetic field, the torque it experience is mathematically represented as
[tex]\vec \tau = \vec B \ X \ \vec m[/tex]
Here X stands for cross - product
From the question we are told that the angle between the vector ( [tex]\vec m[/tex])perpendicular to the plane of the coil and magnetic field(B) as [tex]\phi[/tex]
So
=> [tex]\tau = B * m sin(\phi )[/tex]

What acceleration will all objects experience during their flights through the air (on Earth)?
Answer:
d
Explanation:
Answer:
9.8 m/s/s
Explanation:
As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity
a phosphorus atom needs to gain ---electrons to achieve a full octet
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.

Jared would describe a square as having four equal sides and four right angles. This is Jared’s __________ of a square. A. model B. hierarchy C. feature D. concept Please select the best answer from the choices provided A B C D
Answer:
d
Explanation:
Jared would describe a square as having four equal sides and four right angles. This is Jared’s conceps of a square.
What are squares?A square has four equal sides, four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width.
Many objects can be found in your surroundings that have a square shape. The chessboard, craft sheets, bread slice, picture frame, pizza box, wall clock, etc. are typical instances of this shape.
A square is a two-dimensional closed shape with 4 equal sides and 4 vertices. Its opposite sides are parallel to each other. We can also think of a square as a rectangle with equal length and breadth.
Therefore, Jared would describe a square as having four equal sides and four right angles. This is Jared’s conceps of a square.

Arrange the following events in the mantle convection process. Use numbers 1-5.
a. Lithospheric plates move in the asthenosphere due to rising and sinking of
materials.
b. The decomposition of radioactive elements causes heat in the interior part of
the Earth
c. Heat slowly rises to the mantle and creates convection current.
d. Heat moves to the core.
e. The process repeats as cycle.
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.
