Assuming constant acceleration or that you want average acceleration, you can use the formula:
acceleration = change in velocity / time
=> acceleration = [ 50 m/s - 15 m/s] / 4 s
acceleration = (35 m/s ) / 4s = 8.75 m/s^2
Answer: 8.75 m/s^2
The answer is <span> H+ low and OH- high. T</span>he hydrogen/hydroxide ion concentration of the unknown liquid becomes H+ low and OH- high.
Answer:
0.0085 Wb
Explanation:
a = Side of square
r = Radius of circle
= Magnetic flux through square loop =
Magnetic flux is given by
For square
The length of the square will be equal to the circumference of the circle
For circle
The flux that passes through the circular loop is 0.0085 Wb
Answer:
7 MW
Explanation:
mass of helicopter, m = 12 Mg = 12000
volume of water in bucket, V = 5 m³
diameter of blade, D = 14 m
density of water, d = 1000 kg/m³
density of air, d' = 1.23 kg/m³
The weight of water and the helicopter is balanced by the thrust produced by the rotor blade of the helicopter.
So, force
F = m x g + V x d x g
F = 12000 x 9.8 + 5 x 1000 x 9.8
F = 166600 N
Let initially the velocity of blade is v
v = 41.96 m/
Power of the helicopter, P = Force x velocity
P = 166600 x 41.96
P = 7 x 10^6 Watt
P = 7 MW
HEY THERE !!
It is called SUBLIMATION.
so the correct answer is (D).
