Yes. That equation is exactly how we write Newton's second law nowadays. Note that the 'x' just means 'times'. It's not another variable. The equation could be written as simply. F = m a .
The answer is; A
Airports are usually controlled by governments because they are the points of entry and exit into a country and therefore should have enough security and customs. The vulnerability of the industry also from factors such as terrorism and weather requires that the government regulates the industry to protect the country's interests.
Answer:
675 Pa.
Explanation:
F = 5+2cos(15t) kN
Area (a) = 8*10-3 m2
Now at t =4 sec
F= 5+2cos(60)
= 5+2*0.5
= 6 kN
Now ,force efficiency is 90%.
Hence,the effectively transmitted force,
Fe = 0.90*6
= 5.4 kN
Hence,pressure is given as,
P = Fe/a
= 5.4*10^3/(8
*10^-3))
P = 675 Pa....answer
Answer:
block is being held in place on a frictionless surface. The block has a mass of 3.9 kg and is held in place on an incline of angle = 32° by a horizontal force F, as shown in the figure below.
Explanation:
Answer:
Lose or gain
Explanation:
Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.
