I'm thinking it is BIOS and UEFI. If it's not it, I'm very sorry
The answer is B. The obvious questions do not always lead to interesting results. This is because if everyone did the same thing every time, we wouldn't find any new data. With variables, we have so many different options, leading to creativity and new data found!
Answer:
As a science fair project, you want to launch an 950g model rocket straight up and hit a horizontally moving target as it passes 33.0m above the launch point. The rocket engine provides a constant thrust of 20.0N . The target is approaching at a speed of 18.0m/s . At what horizontal distance between the target and the rocket should you launch?
= 43.56m
Explanation:
acceleration =
(20 - (0.95 * 9.8) )/ (0.95)
= 10.68 / 0.95
= 11.24 m/s²
we use
s = ut + (1/2) at²
Given that
s= 40
u =0
s = 0 * t + (1/2) (11.24)t²
t = √(66/1.24)
t = √5.87
t = 2.42sec
hence
Horizontal distance = 18 * 2.42
= 43.56m
Answer:
392307.6923 m/s²
Explanation:
t = Time taken
u = Initial velocity = 560 m/s
v = Final velocity = 460 m/s
s = Displacement = 13 cm
a = Acceleration
From the equation of motion we have
The acceleration of the bullet as it passes through the board is -392307.6923 m/s²
Answer:
number of moles = 27.34 moles
the temperature of gas after it undergoes the isobaric expansion = 605 K
Explanation:
Given that:
V = 0.25 m³
P = 250 kPa
T = 275 K
V₂ = 0.55 m³
P₂ = 760 kPa
a)
Using ideal gas equation ; PV = nRT
b) To calculate the temperature of gas after it undergoes the isobaric expansion; we have:
