The airplane's speed relative to the ground is
√ (100² + 25²)
= √ (10,000 + 625)
= √ 10,625
= 103.08 km/hr .
The angle of its velocity north of west is
the angle whose tangent is (25/100)
arctan(25/100) = 14° north of west .
(bearing = 284°)
the residual magnetism is coercive force or coercivity.
What is H in hysteresis?
Hysteresis is characterized as a lag of magnetic flux density (B) behind the magnetic field strength (H). All ferromagnetic materials exhibit the phenomena of hysteresis.
What is hysteresis value?
Hysteresis is defined as the deviation of the contact angle from its theoretical (and mean) value due to physical phenomena like microscopic surface defects and roughness.
What is the use of hysteresis?
In control systems, hysteresis can be used to filter signals so that the output reacts less rapidly than it otherwise would by taking recent system history into account
What is cohesive force ?
Cohesive force is the attractive force between the same type of molecules. It can also be called a collective intramolecular force. : In water, hydrogen bonds are held together by the cohesive force that creates a surface tension

Answer: The mean of the samples is 32.325.
Proportion of the defective unit is =
Explanation:
The point estimate of the mean of the sample:
First calculate the mean of the 40 samples:


The mean of the samples is 32.325.
Defected pieces in the samples whose life span is less than the 26 days = 2
Proportion of the defective unit is =
Stars are not really planets because they are far, far away from our solar system.

She remains the only person to be honored for accomplishments in two separate sciences. Curie received the Nobel Prize in Physics in 1903, <u>along with her husband and Henri Becquerel, </u>for their work on radioactivity.
<h3>What did Marie Curie discover?</h3>
Relentless regardless of a vocation of truly requesting and at last lethal work, she found polonium and radium, supported the utilization of radiation in medication and essentially changed how we might interpret radioactivity. Curie was conceived Marya Skłodowska in 1867 in Warsaw.
- Curie was the first person to win two Nobel Prizes.
- She managed it all without a fancy lab.
- Nobel Prizes were a family affair.
- Curie was the first female professor at Sorbonne University.
- Curie is buried in the Panthéon in Paris.
