<span>If you have an oily or saturated absorbent pad after refueling at a marina fuel dock then the best thing to do with it is:
1) To clean up the spills of fuel immediately with oily or saturated absorbent pad.
2) Moreover, the interior parts of the fuel which are in contact with the fuel should be wiped with the saturated absorbent pad.</span>
Given that,
The radius of a circular path, r = 32 m
The time of one revolution of a rider is 0.98 s.
To find,
The speed of the rider.
Solution,
Let v is the speed of the rider. Speed is equal to total distance divided by time taken.
So, the speed of the rider is 205.16 m/s.
Complete question is;
Does the galvanometer deflect to the left or the right when
a) the magnet is being pushed in
b) the magnet is being pulled out
c) the magnet is being held steady?
Answer:
Option A - when the magnet is being pulled out
Explanation:
Faraday’s law of electromagnetic induction states that: “Voltage is induced in a circuit whenever relative motion exists between the conductor and the magnetic field, and the magnitude of the voltage will be proportional to the rate of change of the flux”.
Now, applying it to the question, When the magnet is moved towards the sensitive center of the galvanometer and then pulled out, the needle of the galvanometer will deflect away from its center position in one direction only but when it is held steady, the needle of the galvanometer will return back to zero.
part 1
mass = ρ x V
mass = 1739 kg/m³ x 3.8 km³ = 6608.2 kg
PE (potential energy)= mgh
PE = 6608.2 kg x 9.81 x 403
PE = 2.61 x 10⁷ J
part 2
megaton of TNT (Mt) =4.2 x 10¹⁵ J
convert PE to Mt:
2.61 x 10⁷ J : 4.2 x 10¹⁵ J = 6.21 x 10⁻⁹ Mt
Answer:
The speed of the bullet at impact equals 57.44 m/s
Explanation:
Since the surface is friction less thus no energy shall be lost in the system
Equating the initial kinetic energy of the bullet with the final potential energy of the compressed spring we get
Potential Energy of the compressed spring is given as
given
k = 120 N/m
m = 11 grams
x = 55 cm
Equating the 2 energies and solving for velocity we get
