What are supersonic speeds?
speeds at 343 m/s exactly
speeds above 343 m/s
speeds below 343 m/s
speeds exactly at the speed of sound
The answer is: B.
speeds above 343 m/s.
:)
Supersonic speeds is speed which is above 343. Hence option B is correct.
What is Speed ?Speed is a rate of change of distance with respect to time. i.e. v=dx÷dt. Speed can also be defined as distance over time i.e. speed= distance ÷ time. It is denoted by v and its SI unit is m/s. it is a scalar quantity. Speed shows how much distance can be traveled in unit time.
To find dimension for speed is,
from formula Speed = Distance ÷ Time
Dimension for distance is [L¹] ,
Dimension for Time is [T¹],
Dividing dimension of distance by dimension of time gives,
[L¹] ÷ [T¹] = [L¹T⁻¹]
Dimension for speed is [L¹T⁻¹].
Supersonic speed is the speed of an object that is above the speed of sound. For objects traveling in dry air of a temperature of 20 °C. Speed of the sound is 343 m/s in dry air.
Hence Option B is correct.

i remember this question from when i had a test to take.
In which situation will the lowest resistance occur?
A. thick wire and high temperature
B. thin wire and high temperature
C.thick wire and cold temperature
D.thin wire and low temperature
C. Thick wire and cold temperature.
Explanation:
The resistance of a wire is given by: R = (ρL)/A
where ρ is the resistivity of the material, L is the length of the wire, A is the cross-sectional area of the wire.
From the formula, we see that the thicker the wire, the larger A, therefore the smaller the resistivity. so, a thick wire will have lower resistivity.
Moreover, the resistance of a wire increases with the temperature. In fact, high temperatures mean more motion of the atoms/electrons inside the wire, so more resistance to the flow of current through it. Therefore, colder temperature means lower resistance.
So, the correct option is thick wire and cold temperature.
Answer:
C. Thick wire and cold temperature.

As the car moves from point A , to point B, and finally to point C, the total energy of the car
A. decreases from point A to point B, then increases from point B to point C
B. increases from point A to point B, then decreases from point B to point C
C. stays the same, but is converted between potential and kinetic energy
D. is lost between points B and C
Answer: C
Explanation:
Energy stays the same, but there’s more kinetic energy the less it moves and mor kinetic energy the more it moves
The conservation of energy allows us to find the correct answer for how the change in mechanical energy is:
C. stays the same, but is converted between potential and kinetic energy.
The mechanical energy of bodies is the sum of the kinetic energy due to motion and the potential energies due to the configuration of the system.
If there is not friction in the system, that is, there are no dissipative forces, the mechanical energy must be conserved at all points, this is one of the important conservation laws of physics.
When applying this theorem to the case of the car moving, the energy is converted from potential to kinetic, on the path from A to B and is transformed from kinetic to potential on the path from B to C, but the total value of the mechanical energy remains constant.
Let's analyze the different claims:
A. False. The stable energy conservation theorem that must be constant at all points.
B. False. Must be constant.
C. True. According to the analysis, the mechanical energy is constant and transforms between potential and kinetic.
D. False. As there is no friction, the energy is not lost.
In conclusion using the conservation of energy we can find the correct answer for the transformation of mechanical energy is:
C. Stays the same, but is converted between potential and kinetic energy.

If the applied load F causes Mx
(-77 N.mm) and Mz
(-81 N.mm) at origin then
determine the My
at origin where d=27 mm
Answer:
[tex]|M_y| = 170.82 \ N.mm[/tex]
Explanation:
From the diagram affixed below completes the question
Now from the diagram; We need to resolve the force at point A into (3) components ; i.e x.y. & z directions which are equivalent to [tex]F_x \ , F_y \ , F_z[/tex]
So;
[tex]F_x[/tex] = positive x axis
[tex]F_y =[/tex] Negative y axis
[tex]F_z[/tex] = positive z axis
Then;
[tex]|M_x| = F_y *27-F_z*11 = 77 ----- equation(1) \\ \\ |M_z| = F_y*4 - F_x*11 = 81 ---- equation (2) \\ \\ |M_y| = F_x *27 - F_z *4 = ? ---- equation (3)[/tex]
From equation (1); Let's make [tex]F_y[/tex] the subject of the formula ; then :
[tex]F_y = \frac{77+11F_z}{27}[/tex]
Substituting the value for [tex]F_y[/tex] into equation (2) ; we have:
[tex](\frac{77+11F_z}{27})4-F_x*11=81 \\ \\ 11(\frac{7+F_z}{27} ) 4- F_x -11 =81 \\ \\ 28+4 F_z - 27F_x = \frac{81*27}{11} \\ \\ 4F_z - 27F_x = 198.82 -28 \\ \\ 4F_z - 27F_x = 170.82 \\ \\ Since \ |M_y| = 4F_z-27F_x \\ \\ Then: \\ \\ \\ |M_y| = 170.82 \ N.mm[/tex]

Which of the following is a field force
Answer:
magnetic, gravity, electrostatic all are field forces
Explanation:
help this help! :)
Among the options provided, both magnetic force and electric force are examples of field forces. Thus, option 1 and 2 is correct.
Explanation:Magnetic force arises due to the interaction between moving charges or magnetic dipoles in a magnetic field. It is responsible for phenomena such as the attraction or repulsion between magnets, the operation of electric motors, and the behavior of charged particles moving through magnetic fields. Magnetic fields are produced by moving charges or currents, creating a force that acts on other moving charges within the field.
Electric force, similarly, arises from the interaction between charged particles within an electric field. This force is responsible for the attraction or repulsion between charged objects, the operation of devices like capacitors, and the behavior of charged particles in electric fields. Electric fields are created by static charges or changing magnetic fields, exerting a force on other charged particles within the field.
Both magnetic and electric forces are examples of field forces because they are transmitted through fields (magnetic or electric fields, respectively) and act at a distance without direct contact between the interacting objects. Conversely, normal force and gravitational force are contact forces, as they require physical contact between objects to manifest.
What’s is inductive reasoning?
Answer:
got this on google and got it right
Explanation:
An example of inductive logic is, "The coin I pulled from the bag is a penny. ... Even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false. Here's an example: "Harold is a grandfather. Harold is bald.
Inductive reasoning is when someone observes data, recognizes patterns within these observations, and then draws a conclusion on these observations that they found.
Let's look at an example.
A 12-oz. coke bottle exploded after an hour in the freezer.
A second 12-oz. coke bottle exploded after an hour in the freezer.
The reasoning that was used here was inductive reasoning.
Although we might want to test a few more 12-oz. coke bottles, we can tentatively conclude that all 12-oz. coke bottles will explode after an hour in the freezer.
Since were using oneservations and recognizing patterns to draw a
conclusion, our conclusion is based on inductive reasoning.
