Answer:
32.66 m/s
Explanation:
The potential energy stored in the spring will impart kinetic energy into the dart:
substitute the values:
Answer: from the land to the ocean
Explanation: Apex
Answer:110v
Explanation:
Current=100 amperes
Resistance=1.1 ohms
voltage=current x resistance
Voltage=100 x 1.1
Voltage=110v
Answer:
C) volts
Explanation:
f = frequency of oscillator = 1 kHz = 1000 Hz
= 12 Volts
L = Inductance of Inductor = 5 mH = 0.005 H
= Inductive reactance
Inductive reactance is given as
=
=
= Capacitive reactance
Capacitive reactance is given as
Impedance of the circuit is given as
Rms Current flowing is given as
A
Rms potential difference across the resistor is given as
volts
Answer:
a
b
Explanation:
From the question we are told that
The spring constant is
The mass of the block is
Considering question a
Generally the weight of the block is mathematically represented as
=>
=>
Generally the force exerted on the spring is mathematically represented as
At equilibrium
=>
=>
=>
Considering question b
Generally the energy stored in the spring is mathematically represented as
Now the potential energy of the block before it is drooped is mathematically represented as
Generally from the law of energy conservation we have that
=>
=>
=>
