Explanation:
Heat = mc(change in temp.)
m=mass , c = specific heat
Rate of flow of heat = heat current = kA/L(T2-T1)
So, mass = density×volume
So, mc(T2-T1)/time =
kA/L(T2-T1)
Substitute the values given as there are a lot of values missing, so the answer can not be obtained.
Answer:
Valence shell
Explanation:
The valence shell contains valence electrons
Answer:
C. 1.04%
Explanation:
The following information has been provided;
Actual density of gold; 19.3 g/cm^3
Observed/measured density of gold; 19.1 g/cm^3
The formula for percent error is given as;
((actual value - observed value)/actual value)) * 100
The percent error of the student's measurement is thus 1.04%
(5 mi/hr) x (1hr/60min) x (10min) = 5 x 10 / 60 = <em>5/6 mile</em>
(5/6 mile) x (1,760 yd/mile) = <em>1,466 and 2/3 yards</em>
Answer:
Force = 6.25
so here correct option is a. 6.25
Explanation:
given data
resistance = 0.05 Ω
uniform magnetic field = 0.5 T
time = 0.1 s
to find out
maximum value of the force acting on the bar during that time
solution
we use here Faraday law of induction in the term of current
and solve here for I via the ohms law instead of the emf
That is end up by dividing by resistance
so here I will be
I = ..............1
I =
I = 25 A
and now l is length of 1 side of square when we solving for the force that is
Force = N*I²*B
Force = 1 ×25×0.5×0.5
Force = 6.25
so here correct option is a. 6.25
