Answer:
The angle through which the wheel turned is 947.7 rad.
Explanation:
initial angular velocity, 
= 33.3 rad/s
angular acceleration, α = 2.15 rad/s²
final angular velocity, 
= 72 rad/s
angle the wheel turned, θ = ?
The angle through which the wheel turned can be calculated by applying the following kinematic equation;
Therefore, the angle through which the wheel turned is 947.7 rad.
Answer:
Applied pressure is 1.08 10⁵ Pa
Explanation:
This exercise is a direct application of Boyle's law, which is the application of the state equation for the case of constant temperature.
PV = nR T
If T is constant, we write the expression for any two points
Po Vo = p1V1
From the statement the initial pressure is the atmospheric pressure 1.01 10⁵ Pa, so we clear and calculate
1 Pa = 1 N / m2
P1 = Po Vo / V1
P1 = 1.01 10⁵ 20/18.7
P1 = 1.08 10⁵ Pa
Answer:
Electricity is which is possessed by the flow of electrons.
Magnitism is the process in which the magnet attract the things which consist magnetic substance.
Power
is calculated by dividing the work done with the time interval of the motion.
Work, on the other hand, is force times the distance traveled. Therefore, we
can calculate as follows:<span>
Power=W/t = mgd/t
90 = 60(9.81)d / 40
d = 6.12 m
Number of steps = 20/6.12 = 3.27 or 3 steps</span>
