sweet-ann [11.9K]

Answer:

1. 150C.

2. 50sec

3.1.5a

Explanation:

1. I = Q/T

Q= 30x5

=150c

2.applying the formulae, I = Q/T

T= Q/I

=500/10

=50sec.

3. using the formulae i=q/t

i= 120/80

=1.5a.

A solid sphere of mass 8.6 kg, made of metal whose density is 3,400 kg/, hangs by a cord. When the sphere is immersed in a liqui
creativ13 [48]

Answer:

A.1900 kg/m^3

Explanation:

We are given that

m=8.6 kg

Density,\rho_s=3400 kg/m^3

Tension,T=38 N

We have to find the density of liquid.

T=mg-\rho_l Vg

g=9.8 m/s^2

Volume,V=\frac{m}{\rho_s}

38=8.6\times 9.8-\rho_l\times \frac{8.6}{3400}\times 9.8

\rho_l\times \frac{8.6}{3400}\times 9.8=8.6\times 9.8-38

\rho_l=\frac{(8.6\times 9.8-38)\times 3400}{8.6\times 9.8}

\rho_l=1867kg/m^3\approx 1900 kg/m^3

Option A is true.

GenaCL600 [577]

Why can you get a shock if you touch a metal doorknob after walking across a wool carpet is because you have gained neutrons; the doorknob has fewer electrons. This is further explained below.

<h3>What are electrons?</h3>

Electrons can be defined as a stable subatomic particles with a negative electrical charge that is found in all atoms and serves as the major carrier of electricity in solids.

In conclusion, You have an unbalanced charge, while the doorknob is neutral. you have gained neutrons; the doorknob has fewer electrons.
