5 0

Answer:

Let's look deeper into it.

Explanation:

Heat energy corresponds to the transfer of thermal energy between two given objects. Temperature itself gives off the measurement of how much thermal energy any given object has.

The higher the measurement, the more heat there is. The lower the measurement, the less heat there is.

A 60 [Hz] high-voltagepower line carries a current of 1000 [A]. The power line is at a height of 50 [m] above the earth. What is

omeli [17]

Answer:

The magnitude of the magneticfield B[T] at a point on the surface of the earth directly below the power line is B=1.496x10^(-6) T.

Explanation:

The distance from the wire to a point in the surface is the heigth of the wire.

The formula for the magnetic field on any point at distance R from a wire conducting alternating current is:

$B=\frac{\mu_0I}{2\pi R} =\frac{(4\pi\cdot 10^{-7}T\cdot m/A)(1000\,A)}{2\pi \cdot 50\,m} =1.496\cdot10^{-6}\,T$

A 33 kg box sits at rest on a tabletop.

aleksandr82 [10.1K]

Answer:

323.4N

Explanation:

Given parameters:

Mass of the box = 33kg

Unknown:

Normal force on the body = ?

Solution:

The normal force of a body is the vertical force the body exerts on another body.

It is expressed as;

Normal force = mass x acceleration due to gravity

Acceleration due to gravity = 9.8m/s²

Normal force = 33 x 9.8 = 323.4N

An egg sinks in fresh water but floats on concentrated salt solution

Neporo4naja [7]

the salt solution exerts a greater up thrust on the egg which balances the weight of the egg, so the egg floats in a strong salt solution but sinks in fresh water
