Only some metals are attracted by magnets; these metals are called ferromagnetic is your answer
Answer:
a) A=0.125 m
b) T = 1.72 s
c) f= 0.58 Hz
Explanation:
a) As we are told that the maximum displacement from the equilibrium position was 0.125 m (from which it was released at zero initial speed), this is the amplitude of the resultant SHM, so, A=0.125 m
b) In order to find the period, we must get the total time needed to complete a full cycle (which means that the block must pass twice through the equilibrium point). We are told that at t=0.860 sec, the block has reached to the other end of the trajectory, and it has passed through the equilibrium point only once.
This means that the period must be exactly the double of this time:
T = 2*0. 860 sec = 1.72 sec.
c) In a SHM, the frequency is defined just as the inverse of the period (like in a uniform circular movement), so we can get the frequency f as follows:
f = 1/T = 1/ 1.72 s= 0.58 Hz
Rope can sustain the mass of 58 kg
while the mass of theif is 75 kg
now if thief want to escape from jail then he must have to accelerate on the rope so that tension will be less than its mass
so here we can say
now we will plug in the values as
now from above equation we will have
so the thief must have to slide down the rope with minimum 2.22 m/s^2 acceleration in order to escape using the rope
The potential energy of the electron-proton system is -2.557× J
In physics, potential energy is the energy held with the aid of an item because of its role relative to different items, stresses within itself, its electric charge, or other elements.
To summarize, potential electricity is the power that is stored in an object because of its role relative to some 0 roles. An item possesses gravitational ability electricity if it is placed at a peak above (or beneath) the zero height.
Potential energy is a strength that an object has due to its function relative to different gadgets. Its miles are referred to as ability as it has the potential to be converted into different sorts of strength, along with kinetic electricity. Capability strength is commonly defined in equations via the capital letter U or from time to time by using PE.
Given distance = 9.00 cm
e=1.6× , k=8.99×109 N m²
So,
The formula for the electric potential energy of the system will be
∪= +/d
∪= 8.99×109×(1.6×)/9×10²
∪= -2.557× J
