A 2450 kg stunt airplane accelerates from 120 m/s to 162 m/s in 2.10s. If the airplane is putting out an average force of 5.8810x10^4 N during this time, what is the average friction force exerted on the airplane by the air?
Answers
Given :
A 2450 kg stunt airplane accelerates from 120 m/s to 162 m/s in 2.10 s.
If the airplane is putting out an average force of [tex]5.8810\times 10^4 \ N[/tex].
To Find :
The average friction force exerted on the airplane by the air.
Solution :
Acceleration is given by :
[tex]a = \dfrac{162-120}{2.10}\ m/s^2\\\\a = 20 \ m/s^2[/tex]
Now, force equation is given by :
[tex]F - F_{friction} = ma\\\\F_{friction} = F-ma\\\\F_{friction} = 58810 - (2450\times 20 )\\\\F_{friction} = 9810\ N[/tex]
Therefore, frictional force exerted in the airplane by the air is 9810 N.
While studying bacterial cells, scientists measure the lengths of the cells in one colony. The chart shows their data. The scientists notice that one measurement stands out. How should the scientists best deal with this measurement? accept it as true and use 85 micrometers in the data when they find the average length accept it as true but say that it is the only cell that has ever been that long consider that there was an error during measuring and collect further data consider that it is possible but very unlikely for these bacterial cells to be so long
Answers
Answer:
Following are the solution to the given question:
Explanation:
Its best approach to this measurement ought to be to indicate that there was a mistake throughout the calculation, as well as the gathering of further details while researching cells for bacteria, directly measuring the cell length of a colony. This chart illustrates its data, which scientists have observed that there's still a measurement.

Cobalt (Co) has an atomic mass of 59 and an atomic number of 27. Which statement correctly describes an atom of cobalt?
O A. An atom of cobalt contains more neutrons than protons.
B. An atom of cobalt contains more electrons than protons.
O C. An atom of cobalt contains the same number of neutrons and protons.
O D. An atom of cobalt contains the same number of neutrons, electrons and protons.
Answers
Answer:
Option A. An atom of cobalt contains more neutrons than protons.
Explanation:
From the question given above, the following data were obtained:
Mass number = 59
Atomic number = 27
Next, we shall determine the number of protons in the atom. This is illustrated below:
Atomic number of an element is simply defined as the number of protons in the atom of the element. Thus,
Atomic number = proton number
Atomic number = 27
Therefore,
Proton number = 27
Next, we shall determine the neutron number. This can be obtained as follow:
Mass number = 59
Proton number = 27
Neutron number =?
Mass number = Proton + Neutron
59 = 27 + Neutron
Collect like terms
Neutron = 59 – 27
Neutron number = 32
Next, we shall determine the number of electrons. This can be obtained as follow:
Since the atom is neutral i.e it has no charge, then, the number of protons and electrons are equal. Thus,
Electron number = Proton number
Proton number = 27
Therefore,
Electron number = 27
Summary:
Mass number = 59
Atomic number = 27
Proton number = 27
Neutron number = 32
Electron number = 27
From the above, we can see that the atom of cobalt contains:
1. More neutrons than protons.
2. The same number of protons and electrons.
Therefore, option A gives the correct answer to the question.
An electric energy distributor supplies each household 220
volts of voltage and 60 A of current. Applying your knowledge on Ohm's Law, in what way your appliances be used at home to maintain a safe amount of current?
Answers
Answer:
Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current
Explanation:
According to Ohm's law, V = IR
V is the potential difference = 220volts
I is the current = 60 A
R is the resistance (Load)
Calculating the load R
R = V/I
R = 220/60
R = 3.67 ohms
Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current
What causes electric current to flow in the loop of wire that turns between an
electric generator's two permanent magnets?
A. Electric charges in the wire loop flow when the magnetic fields of
the magnets frequently switch direction.
B. The magnetic field of the magnets causes a mechanical force to
act on the electric charges within the moving loop of wire.
C. Electrons that flow from the magnets into the loop of wire carry
mechanical energy to the electric charges within the wire.
D. The magnetic fields of the magnets attract the magnetic field of
each of the atoms that make up the loop of wire.
Answers
Answer:
B. The magnetic field of the magnets causes a mechanical force to
act on the electric charges within the moving loop of wire.
The magnetic field of the magnets causes a mechanical force to
act on the electric charges within the moving loop of the wire causes an electric current to flow in the loop of wire that turns between an electric generator's two permanent magnets, therefore the correct option is B.
What is a magnetic field?
A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted. The SI unit of the magnetic field is tesla.
the magnetic field can also be generated as the magnetic effect of electric current for example when current is flown through an electrical wire there is the generation of the magnetic field around the conducting wire
For a simple bar magnet, N-pole and S-pole are the points on a magnet that have the strongest magnetic field. The magnetic field originates from the north pole and terminates in the south pole of a magnet.
The magnetic field of the magnets causes a mechanical force to act on the electric charges within the moving loop of the wire responsible for the electric current to flow in the loop of wire that turns between an
electric generator's two permanent magnets.

Circular motion requires the application of a constant force in which direction?
Outward from the circle
Toward the center of the circle
Toward the object in motion

Answers
The final motion characteristic for an object undergoing uniform circular motion is the net force. The net force acting upon such an object is directed towards the center of the circle. The net force is said to be an inward or centripetal force.
Charles, the 75 kg trampoline artist, lands on a trampoline with a speed of 9.0 m/s.
If the trampoline behaves like a spring with a spring constant of 52,000 N/m, what maximum distance will Charles push down the trampoline before bouncing back up? (Hint: at maximum compression, Charles is not moving.)
Answers
Answer:
The maximum distance Charles will push down the trampoline ≈ 0.342 m
Explanation:
The given parameters are;
The mass of the trampoline artist, m = 75 kg
The speed with which the trampoline artist lands, v = 9.0 m/s
The value of the spring constant of the trampoline, k = 52,000 N/m
Let x represents the maximum distance Charles will push down the trampoline
Therefore, we have;
Kinetic energy = 1/2·m·v²
The kinetic energy with which the trampoline artist lands = 1/2 × 75 × 9.0² = 3037.5
The kinetic energy with which the trampoline artist lands = 3037.5 J
The potential energy stored in a spring = 1/2·k·x² = The kinetic energy with which the trampoline artist lands
∴ 1/2 × 52,000 × x² = 3037.5
∴ x = √(3037.5/(1/2 × 52,000)) ≈ 0.342
The maximum distance Charles will push down the trampoline = x ≈ 0.342 m
