There aren’t many but i would say one is that you’re brain isn’t as active as it was while you were working and also your not exercising as much as you were while in your old job (depends on your job)
I think it would be yes because the drum is submerged in water and the water would slow the sound waves, making the sound softer. Right?
Answer:
I = 1.05x10⁻³ A
Explanation:
By definition, an electric current is the rate of charge flow at a given time:
Where:
q: is the electrons charge = 1.602x10⁻¹⁹ C
t: is the time
In a circular motion, the time is given by:
Where:
ω: is the angular speed = v/r
v: is the speed = 2.19x10⁶ m/s
r: is the radius = 5.29x10⁻¹¹ m
Now, the effective current is:
Therefore, the effective current associated with this orbiting electron is 1.05x10⁻³ A.
I hope it helps you!
Answer:
Impulse is defined as change in momentum of an object divided by time interval.
at t= 0s
initial velocity = u , initial momentum = mu
at some time t .
final velocity = V, final momentum= mv.
now, change in momentum= ( final - initial) = ( mv-mu)
time interval = (t-0) = t
impulse force = (mv-mu)/ ( t)
Ft = (mv-mu) proved .
this law is known as Newton's second law.
Recall the equation relating an object's change in thermal energy to its change in temperature:
ΔQ = mcΔT
ΔQ is the change in thermal energy.
m is the mass of the object.
c is the object's specific heat.
ΔT is the object's change in temperature.
Given values:
m = 0.5 kg = 500g
ΔT = (7-0)⁰C = 7°C
Online sources say the specific heat of silver is 0.240 J/g⁰C
Substitute the terms in the equation with the given values and solve for ΔQ:
ΔQ = 500×0.240×7
<h3>ΔQ = 840 J</h3>
