Answer:
in what context?
Explanation:
thermal resistivity is the property of an object to resist transmission of heat.
electrical resistivity is the property of an object to resist transmission of electricity.
Answer:
15 V
Explanation:
Electric potential is given as the product of Electric field and distance. Mathematically:
V = E * r
Where E = Electric field
r = distance = 6m
Electric field, E, is:
E = F / q
Where F = Electric force = 5N
q = Electric charge = 2C
Therefore, electric potential will be:
V = (F * r) / q
V = (5 * 6) / 2
V = 15V
36/12= 3 3 IS THE AMOUT OF HALFLIVES
ONE HALF LIFE = 300
TWO HALF LIFE = 150
THREE HALF LIFE = 75
*Divide 600 three times
The Young’s modulus of polythene is 0.8
Answer:
Explanation:
a) I = ½mR² = ½(19)(0.15²) = 0.21375 kg•m²
b) τ = Fnet(r) = (25 - 12)(0.15) = 1.95 N•m
c) CCW
d) a = τ/I = 1.95 / 0.21375 = 9.12280701... = 9.1 rad/s²
e) CCW
