What is the difference between mass and height?

1 answer:

7 0

Well for one:

mass:<span> mass is a property of a physical body. It is the measure of an object's resistance to acceleration when a force is applied. It also determines the strength of its mutual gravitational attraction to other bodies.
</span>
height: is a measurement from top to bottom

so for an example: my height is 5'3" and my resistance is maybe 100lb

A current of 1.75 A flows through a 55.4 Ω resistor for 9.5 min. How much heat was generated by the resistor? Answer in units of

kirill115 [55]

Answer:

$9.67\times 10^4 J$

Explanation:

We are given that

Current=I=1.75 A

Resistance =R=55.4 ohm

Time=t=9.5 min= $9.5\times 60=570 s$

1 min=60 s

We have to find the heat generated by the resistor.

We know that

Heat=E= $I^2Rt$

Using the formula

Heat, $E=(1.75)^2\times 55.4\times 570=9.67\times 10^{4} J$

Hence, the heat generated by the resistor = $9.67\times 10^4 J$

What is Lorentz law?

Reika [66]

These two electric and magnetic forces can be related together into one electromagnetic force through the Lorentz force law. This law states that the total force acting on a charged particle due to electric and magnetic fields is equal to the sum of the electric and magnetic forces acting on it.

What is the speed of a wave if the wavelength is 50 meters and the period is 10 seconds?

Karolina [17]

Based on the information you provided, this means the wave is traveling 50 meters every ten seconds. Meaning it is traveling 50/10 meters per second.
When you simplify you get 5 meters per second.
