Sorry i can’t help sorry good luck tho!!!!
It depends on the force that is applied to the object.
Answer:
x = 259 Hz
Explanation:
given,
frequency of one tuning fork = 250 Hz
frequency of another tuning fork = 266 Hz
when a tuning fork is sounded together beat frequency heard = 9
let x be the frequency of unknown
x - 250 = 9 Hz..............(1)
x = 259 Hz
when a another tuning fork is sounded together beat frequency heard = 7
266 - x = 7 Hz..............(2)
x = 259 Hz
now, on solving both the equation the frequency comes out to be 259 Hz.
so, The frequency of the tuning fork is equal to 259 Hz
chemical energy converts into light, heat and sound energy
Answer:
The magnitude of a uniform electric field that will stop these protons in a distance of 2 m is 1.01 x 
N/C
Explanation:
given information,
kinetic energy, KE = 3.25 x 
J
proton's mass, m = 1.673 x 
kg
charge, q = 1.602 x 
C
distance, d = 2 m
to find the electric field that will stop the proton, we can use the following equation:
E = F/q
= (KE/d) / q , KE = Fd --> F = KE/d
= KE/qd
= (3.25 x J) / (1.602 x C)(2 m)
= 1.01 x N/C
