Answer:
Impulse is related to momentum because impulse is a term that describes object's change in momentum. The measurable quantity of momentum changing is called impulse.
Answer:
4°
Explanation:
Given,
chord in the airstream, c = 2 m
speed, v = 50 m/s
lift per unit span = 1353 N/m
density of air, ρ = 1.225 kg/m³
Lift,
From the plot of c_L and angle of attack
Angle of attack is equal to 4°
Answer: C. depends just on the B field going through the loop
Explanation:
If the magnetic field changes, or if the size of the loop changes, or if the orientation of the loop changes, then the flux through the loop can change. A change in flux induces an emf in the loop.
Magnetic flux is what generates the field around a magnetic material. ... The SI unit of magnetic flux is the Weber (Wb) (in derived units: volt-seconds). The CGS unit is the Maxwell. Magnetic flux is sometimes used by electrical engineers designing systems with electromagnets or designing dynamos.
15 number of division on Vernier scale and 12 cm on the main scale means 13.2 cm of the object thickness.
<h3>What is value of 15 division of Vernier scale generally?</h3>
A Vernier scale has 10 divisions and the total length of these 10 divisions is equal to the length of 9 divisions of the main scale that equals to 9 mm so in this way 15 number of division on Vernier scale means 14 divisions on the main scale which is equals to 14 mm and we know that there is 12 cm on the main scale so by adding 12 cm and 14 mm we get the 13.2 cm reading of the object thickness. Vernier caliper is a measuring device that comprise of a main scale and a sliding jaw with an attached Vernier.
So we can conclude that 15 number of division on Vernier scale and 12 cm on the main scale means 13.2 cm of the object thickness.

Answer:
Moment is an expression involving the product of a distance and physical quantityA moment is due to a force not having an equal and opposite force directly along it's line of action. ... It is defined as the product of the force (F) and the moment arm (d). The moment arm or lever arm is the perpendicular distance between the line of action of the force and the center of moments.Moments act about a point in a clockwise or anticlockwise direction.
