Answer:
29.4 J
Explanation:
gravitational potential energy =mgh
Where m is the mass h is the height about ground
and g the acceleration due to gravity
g=9.8ms−2
Hence 2⋅1.5⋅9.8
=29.4 J
Use the value of g you have been taught to use, some people advise using 9.8 or 9.81 but some use 10
Well visual and perceptual are both the way you see things and tactile is touch so it has to be Olfactory
Explanation:
It is given that,
Resistance of the resistor,
Capacitance of the capacitor,
Inductance,
rms value of voltage,
The Ac source is operating at,
The inductive reactance of the inductor is given by :
The rms value of current is :
The rms voltage across the inductor is given by :
So, the voltage across the inductor is 4.8 V. Hence, this is the required solution.
Answer:
Explanation:
The probability to find a particle in a 1 dimension box of length is:
Let's recall the wave function of a particle in this candiction will be:
So the propability:
Solving the integral, it is:
We can cancel out <em>a</em> and using n = 10, the probabilty finally will be:
I hope it helps you!
Given: Change of x is 35.4m, Velocity Final=7.10 m/s, Velocity Initial=0m/s
Find: Acceleration
Analysis:
Vf²=Vi²+2aΔx (Velocity final squared equals Velocity initial squared plus 2 times acceleration times change of x)
(7.10 m²/s)²=(0 m/s)²+2a(35.4 m)
50.41 m/s²=(70.8 m)a
a=0.712 m/s²
