Answer:
Acceleration,
Explanation:
It is given that,
Initial speed of the jetliner, u = 69 m/s
Final speed of the jetliner, v = 6.1 m/s
Distance covered, s = 750 m
We need to find the average acceleration of the jetliner. It can be calculated using third equation of motion as :
So, the average acceleration of the plane during landing is . Hence, this is the required solution.
Answer: Worm
A virus spreads from one machine to another rapidly without human action. A virus is like a code that runes automatically without any knowledge or without taking permission of the user. It hampers the way a machine works. When a machine is attached to another machine directly or indirectly containing virus, it spreads itself. A worm is a kind of virus that can spread with zero human intervention. A virus still requires a human to download a contaminated file but worm does not. a worm can spread on its own
Answer:
AM broadcasts occur on North American airwaves in the medium wave frequency range of 525 to 1705 kHz (known as the “standard broadcast band”). The band was expanded in the 1990s by adding nine channels from 1605 to 1705 kHz.
Answer:
the direction of the velocity is downward and the acceleration decreases throughout the motion
Explanation:
since the gradient is negative it is decelerating
<span>A particular frost-free refrigerator uses about 710kWh of electrical energy per year. You are to express this amount of energy in J, kJ, & Calories.
1 year (365 days / 1 year)(24 hours / 1 day)(3600s / 1h) = 31,536,000s
710 kWh/yr (1 yr) = 710 kWh
710 x 10^3 Wh = </span>710 x 10^3(J/s)(31,536,000s)<span> = 2.24 x 10^13 J
</span>2.24 x 10^13 J = 2.24 x 10^10 kJ = 5.35 x 10^12 cal
