How do you find the weight of an object underwater

Physics
1 answer:
iren2701 [21]4 years ago
4 0

Answer:

Explanation:

But Archimedes principle states that the buoyant force = weight of fluid displaced by object. From this volume you can get the mass of water displaced since the density of water is 977kg/m^3. Whatever you get multiply it by 9.8m/s^2 to covert mass to weight.

Copper wire is 1. 9 mm in diameter and carries a current of 20 a. What is the electric field stregnth inside this wire?
Tju [1.3M]

The electric field strength will be 0.6252 V/m. It is the strength at which the field is created by charges.

<h3>What is electric file strength?</h3>

The electric field strength is defined as the ratio of electric force and charge.

The electric field strength is found as;

\rm E = \frac{I \rho }{A} \\\\ \rm E = \frac{20  \times 1.68 \times 10^{-8} }{ (0.6385 \times 10^{-6}} \\\\ E= 0.5262 \  V/m

Hence, the electric field strength will be 0.6252 V/m.

zhenek [66]

Answer:

1. The displacement is 427.2 km.

Explanation:

1. A = 150 km North

B = 400 km East

The net displacement is given by

R =\sqrt{400^2 + 150^2 }\\\\R = 427.2 km
